College Essays

The California Institute of Technology—or Caltech, as it's more commonly known—is a highly exclusive college. If you want to join the Beavers, you'll need not just top grades and standardized test scores, but strong writing supplements to support them as well.

Caltech accepts around 6% of students who apply, making it an extremely competitive school . The more you know about the Caltech essay prompts before you start, the better prepared you are to answer them.

BREAKING: Caltech Application Changes Due to COVID-19

As a result of the novel coronavirus pandemic, many colleges have made the decision to at least temporarily stop requiring SAT and ACT scores. In June 2020, California Institute of Technology announced that they will stop considering SAT and ACT scores of applicants for the next two admission cycles (those applying in fall 2020, 2021, and 2022). This means that, not only are SAT and ACT scores not required, but, even if you submit them, they won't be reviewed and they won't be considered as part of your application. (This is what we refer to as a "test blind" policy.) Additionally, international students can now meet Caltech's English proficiency requirement by submitting either TOEFL or Duolingo scores.

Because of SAT and ACT cancellations , as well as the difficulty some students are having preparing or paying for the tests, Caltech made the decision to temporarily stop requiring standardized test scores to make admissions as fair and equitable as possible. Because test scores aren't being considered, there will be an increased emphasis on classes students took and the grades they received in them.

What Do I Need to Know About the Caltech Essays?

Caltech accepts four different applications: Coalition, Common App, Powered by Scoir, and Questbridge. In addition to the required Coalition,  Common Application, and powered by Scoir essays, Caltech also requires three short essays. ( Questbridge applicants only need to write these if they become Match Finalists and have ranked Caltech.)

You’ll write one required academic question and three required short answer questions, but you’ll also have the option to answer three supplemental short answer questions and one supplemental academic question, if you want.

Altogether, you'll be writing up to 1100 words for the required essays, and 300 words for the optional short answer questions. These essays are fairly short, so you'll want to spend a good amount of time honing your argument to its most efficient. Start early so you have plenty of time to plan, refine, revise, and proof before you submit!

Do a little preparation and you can look this happy when writing your Caltech essays, too!

What Are the Caltech Essay Prompts?

The Caltech essay prompts are fairly standard, though each one is tailored to the college's specifications. You'll see the usual "Overcoming Obstacles” and “Defining Your Fit” essay questions, but always keep in mind that you're applying to Caltech specifically, and your essays should reflect that.

Required Academic Question

Because of the rigorous core course curriculum, Caltech students don't declare a major until the end of their first year. However, some students arrive knowing which academic fields and areas already most excite them, or which novel fields and areas they most want to explore. If you had to choose an area of interest or two today, what would you choose? Why did you choose that area of interest? (Max: 200 words)

The first essay asks you share your academic passion (or passions), and how you discovered them. Many colleges understand that students change their majors throughout the course of their careers, and Caltech doesn’t want you to have to choose a major until you’re a sophomore. But they still want you to have a good idea of what you want to focus on and why it matters to you.

The key here is to be specific about your area of interest. Note that they don’t mention a major, but instead an overall field. In other words, now isn’t the time to say that you want to major in biology because you’ve always done well in school. Instead, focus on something more specific, like a problem you want to solve or an experience that changed the way you see your career. Maybe your physical science egg-drop challenge inspired a desire to create safer structures, or maybe a field trip to a NASA location made you realize you had to be in that control room one day.

Whatever the case, be as specific as you can with what you want to study, and remember that multiple majors could get you there. For example, visiting NASA could have inspired you to study mathematics, physics, or engineering. There are multiple paths to reach the same goal; do your homework, look at the different programs Caltech offers, and choose one or two that align with your dream.

Caltech is, in their own words, “an unapologetic STEM institution.” Whatever you do, make sure that your chosen area fits within these parameters.

Required Short Answer Question #1

At Caltech, we investigate some of the most challenging, fundamental problems in science, technology, engineering, and mathematics. Identify and describe two STEM-related experiences from your high school years, either in or out of the classroom, and tell us how and why they activated your curiosity. What about them made you want to learn more and explore further? (Min: 100/Max: 200 words for each experience)

This prompt is asking you to discuss something you're passionate about. Your interests and activities outside of school and work can reveal a lot about the kind of person you are. As such, this prompt is a great opportunity to show how you exhibit the characteristics of the perfect Caltech candidate in your life experiences that don’t show up in your test scores and GPA.

Hopefully, thinking of a topic for this essay will be easy for you. You should write about a situation, story, or topic that gets you so engrossed and excited that it’s tough to tear yourself away from learning about it! Whether that’s reading up on the psychology of conspiracy theories or bird watching with your little brother, the most important thing is that you choose something that you’re deeply interested in. When you do that, admissions counselors will be able to feel your passion too!

Even though you probably could write pages and pages about the topic you choose, it’s important to keep things clear and concise here. Remember: you only have 200 words per topic to work with! To keep your essay focused, tell the story of how these experiences piqued your curiosity into the subject (or subjects) you’ve chosen to write about. You can describe your learning process, even if it’s quirky or unconventional. This is your chance to show Caltech how you choose to expand your mind when left to your own devices.

And that’s the most important thing to emphasize in your essay. Caltech is looking for students who don’t stop learning when the semester ends. The people who make a difference in the world are passionate, lifelong learners. This essay is your chance to show off your niche interests and prove to Caltech that you’re a lifelong learner too.

This guy would fit right in at Caltech.

Required Short Answer Question #2

The creativity, inventiveness, and innovation of Caltech's students, faculty, and researchers have won Nobel Prizes and put rovers on Mars , but Techers also imagine smaller scale innovations every day, from new ways to design solar cells to 3D printing dorm decor. How have you been an innovator in your own life? (Min: 200 / Max: 250)

This question is a great way for you to show off your skills! Maybe your insight helped your school’s robotics team take home first place, or maybe you found a way to streamline some part of your family’s day-to-day routine. You have a lot of options here, but make sure to keep your topic focused on STEM-related subjects. This is an excellent topic for a problem-and-solution essay: after all, your innovation will have improved a situation, right? You only have 250 words, so you’ll need to make them count! Caltech wants to see how your mind works : why were you driven to your chosen innovation? Were there any obstacles? What was the end result, and how was it received?

Remember:  you'll need to give the admissions counselors enough information that they can understand your innovation and  its impact. Be sure to answer both parts of this question so that you're fully addressing the prompt. 

It probably wasn't one of these kids who wrote these successful Caltech essays.

Required Short Answer Question #3

The process of discovery is best advanced when people from diverse backgrounds come together to solve the greatest challenges in their fields. How do your past experiences and present-day perspectives inform who you have become and how you navigate the world? (Min: 200 / Max: 250)

This is your chance to show Caltech what makes you tick, and how you’ve become who you are. Think back on the formative experiences in your life: your home, your family, your cultural background. How have they shaped you into who you are now and what you want? Show Caltech how you see the world, and why.

As always, you should remember to gear this toward STEM as much as you can: Caltech isn’t kidding when they tell you to “lean all the way in on the STEMiest of STEMmy topics.” The trick here is to show how your own lived experiences have informed your interest and perspective on the STEM subject that you’re most drawn to. Maybe you come from a family of artists, and their sense of aesthetics informs the way you design and present your projects. Maybe you have a different cultural background than most of your peers, which influences your thought processes.

Be sure to tell a story here so that you can connect with admissions counselors. For example, was there a formative experience in your childhood or youth that made you realize you stand out from your peers in some way? Was a family member or cultural tradition particularly influential?

CalTech Short Answer Questions

Along with longer essays, you'll also have to tackle a few short answer responses, too. We'll break them down below! 

Supplemental Short Answer Question #1

If there are aspects of your identity that you feel are not captured elsewhere in this application, please provide that information below. (Max: 150 words)

This is a pretty broad prompt! Unlike Required Question 3, which asks about your background, or Supplemental Question 2, which asks about your hobbies, this is about your identity, which includes both of those things and more! You have a lot of options here: think of past experiences that made you realize more about who you are and what you stand for. Maybe you stood up to a bully. Maybe you went stargazing with family or friends, and found yourself overwhelmed by the vastness of the universe. Just like with the other prompts, remember to be as specific as possible, and give examples.

Supplemental Short Answer Question #2

When not surveying the stars, peering through microscopes, or running through marathons of coding, Caltech students pursue an eclectic array of interests that range from speed-cubing to participating in varsity athletics to reading romance novels. What is a favorite interest or hobby and why does it bring you joy? (Max: 100 words)

This is a great prompt to answer, because it gives you the chance to show the admissions counselors more about who you are not just as a budding scholar but as a person. Here’s a chance to open up about, say, your passion for rock climbing or your increasingly-large collection of succulents. You only have 100 words, but try to go into as much detail as possible about how your hobby makes you feel. This is the place to be descriptive, and to show rather than tell.

Supplemental Short Answer Question #3

Did you have a hard time narrowing it down to just one interest or hobby? We understand – Caltech students like to stay busy, too – tell us about another hobby or interest! (Max: 50 words)

You've probably got more than one hobby you love. This is your chance to share that with admissions counselors at CalTech. You don't have much space, but help your readers understand why you're passionate about the hobby you choose. 

Caltech Essays That Worked

All this information is great, but it can still be tricky to understand exactly what Caltech wants to know until you've seen it demonstrated. Check out this accepted essay—and some tips from someone who took a serious risk—to learn more about what Caltech hopes to see in your essay!

Even though the example essays below respond to old essay prompts, there’s still a lot you can learn from them about how to write successful Caltech essays.

Martin Alternburg's Essay

I cross over the bridge into Minnesota. Out of my three sports, cross country is definitely my worst — but I continue to be hooked on it. Unlike swimming and track, my motivation to run is heavily intrinsic. I live for the long runs I take on by myself. While they rarely happen during our season, we were assigned a long run to complete over our first weekend of cross country. In reality, I was supposed to go six miles, but felt eight gave me more time to explore the home I had just returned to. My mind begins to wander as I once again find my rhythm. My train of thought while running is similar to the way one thinks in the minutes before sleep — except one has more control over how these thoughts progress and what tangents they move off of. While special relativity would be the "proper" thing to think about, especially at MITES, I revive the violin repertoire I had turned away from for so long and begin playing it in my head. I'm now at the edge of town in between the cornfields. The streaming floodlights on the open road give me a sense of lonely curiosity, reminiscent of the opening lines of Wieniawski's first violin concerto. I come up with adaptations of the melody in my head, experimenting with an atonality similar to Stravinsky's.

Martin Altenburg's essay is well-structured, using the narrative of a morning run to demonstrate all the things that run through his head, and, more importantly, all the unique traits that make him who he is.

From just these two paragraphs, we know he's a runner, that he's driven, that he strives for more than he thinks he's capable of, and that he knows music and composition. Because the essay is in a narrative format, we're able to follow this line of thinking and have it all wrapped up neatly at the end. We're drawn in by energetic and purposeful writing that also delivers us all the information we need.

Throughout the essay, Altenburg discusses his interests and his growth. His strategic use of locations in his hometown allows readers to understand where he comes from both literally and figuratively, especially the part about his beliefs and how the community he's grown up in have impacted them. All this is valuable information to an admissions office, who wants to see how you see yourself and why.

One thing to note about this essay is that it doesn't include any reference to Caltech. In fact, Altenburg used the same essay to apply to—and get into—eight different Ivy Leagues as well as some other schools. The essay was likely written as part of the Common or Coalition Application rather than as part of Altenburg's Caltech supplement, hence the lack of specificity. Your essays for the Caltech supplement should contain more specificity than this, as these essays are unique to Caltech and want to know exactly what draws you to that school above others.

Michelle Fan's Essay Reflection

"How do you believe Caltech will best fuel your intellectual curiosity and help you meet your goals?" If I had a few weeks, I might have done enough research to namedrop a few professors, rave about the strength of their computer science programs, and come up with a compelling story about all my professional goals. But I didn't have those few weeks, so I told them the unembellished, wholehearted truth: I said I have no idea what I want to do in life. All I knew was that I liked making calculator games and explosions and wanted to participate in the bread-throwing, water-dumping congregations otherwise known as Caltech house dinners. As it turns out, being yourself actually works. Shocker, I know. Colleges really do want to like you for you.

Michelle Fan doesn't post her Caltech essay directly, but she does talk about her process and what she discovered between her highly planned essays and the ones she wrote the day they were due.

Fan points out that her last-minute essays, the ones that she wrote from her heart rather than from her head, are the ones that got accepted. Though I definitely don't advocate for waiting until the same day that your essay is due to start writing it, it's a good message to keep in mind—when you're faced with an imminent deadline and you just need to get something out, your writing is probably more genuine than if you've been editing and revising it for ages.

But the big takeaway here should not be to wait until the last second to write your essay (please, don't do that!). The real lesson is that you should write in a way that is true to yourself, not a way that you think will impress admissions offices. You should be authentic and genuine, letting your personality and interests tell Caltech why you're a good fit.

If your essay looks like this, that's a good thing!

4 Key Tips for Writing a Caltech Essay

Like all college essays, there are some general things to keep in mind when working on your Caltech writing supplement. The earlier you get started, the better—take a little time to make sure that your essay is as polished as possible!

Brainstorming before you start writing will help you pick a topic that's both meaningful and impressive. Jotting down a list of ideas for each topic, no matter how silly they might feel at first impression, gives you options. Spend a little time away from your options so that you can pick the one that you feel most strongly about with less bias!

#2: Get People to Read Your Essays for You

Feedback is an important tool as a writer. Getting someone else to look at your work—preferably someone who will be honest about its shortcomings—will help you find logical holes, weird phrasing, and other errors that may creep into your work. When you feel like your essays are as polished as you can make them is a good time to hand them off to someone else. Remember, you don't have to make every change they suggest exactly as they suggest it, but if your reader is confused about something, see what you can do to make it clearer!

#3: Edit and Revise

Take that feedback you got from your reader and turn it into gold. Again, don't feel like their suggestions are always the right move, but do consider what's causing their confusion or dislike for parts of your essays. Fix them in your own voice, and re-read your essay, especially out loud, to catch any additional errors. The more time you can spend revising, the better!

#4: Be Authentic

Always remember that you're not just trying to impress Caltech with a bunch of statistics—you're trying to impress them as you. That means always staying true to yourself and striving for authenticity. Give Caltech an essay that showcases what it means to be you, not an essay that gives them what you think that they want to hear.

A strong essay is just one part of a successful Caltech application. Also look into Caltech's SAT scores and GPA requirements so you can draft an effective academic plan!

Before you send in your Caltech application, it's a smart idea to figure out how much money it's going to cost you to attend. How do Caltech's financial aid offerings measure up to tuition costs?

How to Write the Caltech Supplemental Essays

Admissions officer reviewed by Ben Bousquet, M.Ed Former Vanderbilt University

Written by Alex McNeil, MA Admissions Consultant

Key Takeaway

The California Institute of Technology, or Caltech for short, is a small but highly selective school that focuses primarily on STEM disciplines.

The Caltech supplemental essays are divided into two groups: required and optional. You’ll have five required essays to write (that’s quite a few!) and three optional essays to choose from.

Let’s start with the required essays.

Required Caltech Essays

Before you write anything, Caltech asks you to use a drop-down menu to choose an academic area that interests you. Don’t worry—this isn’t a declaration of your major. In fact, at Caltech, you don’t have to declare a major until the end of your first year.

But your first essay question revolves around the academic area you select, so choose whatever calls most to you right now.

Here’s the first prompt:

Why did you choose that area of interest? (200 words)

In this why this major or academic interest essay, you’ll want to be clear about the why behind your interest in that particular area.

Were you inspired by an experience or person? Is there a question that fascinates you? Is it related to a career goal?

In your answer, feel free to highlight any relevant accomplishments you have. For example, if you chose chemical engineering and you spent your junior year summer helping a chemistry professor with research, then bring it up!

This is also a place to draw upon any related references to Caltech itself. What about their program entices you? Are there any specific opportunities you’re interested in?

The next two questions go hand in hand. You’ve got 200 words to answer each of them. Here’s the main prompt:

At Caltech, we investigate some of the most challenging, fundamental problems in science, technology, engineering, and mathematics. Identify and describe two STEM-related experiences from your high school years, either in or out of the classroom, and tell us how and why they activated your curiosity.  What about them made you want to learn more and explore further?

STEM experience/activity #1

STEM experience/activity #2

These essays are your opportunity to highlight special projects or accomplishments that show magnitude, reach, and impact .

Because Caltech asks for STEM-related experiences or activities, you’ll need to choose something that relates to science, technology, engineering, or math. This isn’t the time to take a creative twist on the prompt (”Writing poetry was like science to me!”) because your essays will be read alongside applications from some of the best high school scientists in the world.

As you answer, don’t forget to address the three main questions of the prompt:

Identify and describe the experience. It can be in or out of the classroom.

Explain how it “activated your curiosity.”

Explain how it made you want to learn and explore more.

Feel free to nerd out a little and go in-depth on a topic you’re passionate about. It can complement, be related to, or be completely different from your answer to prompt #1. Just think about how all of your supplemental essays will work together to form one overall narrative .

The creativity, inventiveness, and innovation of Caltech’s students, faculty, and researchers have won  Nobel Prizes  and put  rovers on Mars , but Techers also imagine smaller scale innovations every day, from new ways to design solar cells to 3D printing dorm decor. How have you been an innovator in your own life? (250 words)

In your essay, you can take “innovator” literally or figuratively. Either way, you’ll want to balance your answer to this question with your answers to the previous two.

If you’ve literally innovated something, now’s your time to shine. Did you create an app to help your classmates study for your French final? Did you design a website for your mom’s small business or develop a code to count cars ? Draw out the key points for your admissions officers, and make sure it’s clear why your innovation mattered (to you and to those around you).

Or, if you haven’t literally innovated something, you might think about innovation more metaphorically and use this prompt to show admissions officers a softer or more creative side of yourself. Maybe you innovated a new way to teach algebra to your tutee or rediscovered the design for The Apple Picker 5000 that you drew up when you were five years old. Just be sure to draw out what it all means for who you are as a technical innovator now.

The process of discovery is best advanced when people from diverse backgrounds come together to solve the greatest challenges in their fields. How do your past experiences and present-day perspectives inform who you have become and how you navigate the world? (250 words)

By this point, you’ve shown Caltech admissions officers your academic and technical side and maybe let them in on a few important stories from your life.

With this final required prompt, it’s time to dig a little deeper. This is a diversity essay .

Caltech admissions officers will know from the rest of your application why you’ll make a good scientist. Now you need to show them who you are as a person.

Feel free to write about any area of your identity that has shaped your perspectives. Also pay attention to the wording of the prompt: admissions officers want to know about your past experiences AND present-day perspectives. What’s more, they specifically want to know how they inform 1) who you’ve become, and 2) how you navigate the world.

You could write about a particular part of your upbringing, what it’s like to live in the world with a particular identity, or even an impactful experience you had that changed your perspective.

Optional Short Answer Questions

Here’s what Caltech says about the “optional” designation: “Optional. We promise.”

Take their word for it. Choosing not to answer these questions won’t automatically get your application tossed into the reject bin.

But choosing not to answer them is also a choice not to add to your cohesive application narrative . Answering the questions can give admissions officers more information to get to know you with (and therefore more data to base an admissions decision on!).

Let’s take a look at the optional prompts.

If there are aspects of your identity that you feel are not captured elsewhere in this application, please provide that information below. (150 words)

You may have covered everything you needed to cover in the last required prompt, but this prompt gives you more space if there’s something else you want to convey.

Applicants answering this prompt might choose to write about gender identity or sexuality, race or ethnicity, ability or disability, class, or general background information.

Whatever you write about, make sure there’s a clear takeaway for admissions officers.

When not surveying the stars, peering through microscopes, or running through marathons of coding, Caltech students pursue an eclectic array of interests that range from speedcubing to participating in varsity athletics to reading romance novels. What is a favorite interest or hobby and why does it bring you joy? (100 words)

The other required and optional prompts are all pretty straightforward. But this one gives you leeway to show some personality.

Note the emphasis on “joy” in the prompt. This isn’t just about a hobby that you’ve excelled at or participated in for a long time. It’s about describing something that makes you genuinely happy, even if it’s not a world-changing activity.

Think of your answer to this prompt as the sprinkles on top of your application. It’s a way to have some fun and add a little narrative diversity.

Did you have a hard time narrowing it down to just one interest or hobby? We understand – Caltech students like to stay busy, too – tell us about another hobby or interest!  (50 words)

And here you can elaborate just a little more on a secondary hobby if you’d like. Just make sure it’s actually adding valuable information to your file, otherwise admissions officers may simply skim it and move on.

And with that, you’ll have written all your Caltech supplemental essays! Remember: you have to answer the first four, but you aren’t required to write any in the last set unless you want to.

Whichever ones you write will all work towards your cohesive application narrative , so think about them each as an opportunity to advocate for your admission. Make them count.

You’ve got this!

Caltech Supplemental Essays 2023-24 – Prompts & Advice

September 14, 2022

With a 2.7% acceptance rate (yes, truly), Caltech is one of the most highly selective schools in the country. Amazingly, they have managed to operate as a test-blind institution throughout the pandemic and will continue to do so until 2025 . This means that they do not presently consider ACT or SAT results in the admissions process. As such, the Caltech admissions committee gives extra weight to the five supplemental essay prompts that they require from all applicants.

 (Want to learn more about How to Get Into Caltech? Visit our blog entitled:  How to Get Into Caltech  for all of the most recent admissions data as well as tips for gaining acceptance.)

Before we dive right in and begin examining the five required and two optional 2023-24 Caltech essays, one quick note…  the admissions committee has provided in-depth guidance for three of the five required essays , so we’ll keep our advice for those short and sweet.

Caltech Supplemental Essays – Prompt #1 (required)

Why did you choose that area of interest? (200 words)

(Note: you’ll select 1-2 areas of interest from a provided drop-down box on the application)

We all have a story of what drives us to pursue a certain academic pathway and career. How did your interest initially develop? What was the spark? How have you nurtured this passion and how has it evolved over time? If you desire to go into engineering, this is a chance to talk about everything from your childhood fascination with how things work to your participation in an award-winning robotics program at your high school. Share a compelling (and, of course, true!) narrative about how your love of your future area of study has blossomed to its present levels.

In other words, this essay should show evidence of intense hunger for knowledge that extends well outside of the classroom. How do you learn about your favorite subjects? What books have you read on the subject? Which podcasts have you listened to? What museums have you visited? What related experiences have you had?

You should also tie your passions into specific academic opportunities at Caltech including  courses ,  professors ,  hands-on research programs , or any other aspects of your desired major that appeal most to you.

Caltech Supplemental Essays – Prompts #2 & #3 (required)

At Caltech, we investigate some of the most challenging, fundamental problems in science, technology, engineering, and mathematics. Identify and describe two STEM-related experiences from your high school years, either in or out of the classroom, and tell us how and why they activated your curiosity. What about them made you want to learn more and explore further? (100-200 words for each experience)

Main note here—you won’t be writing about both experiences within the same response (phew!). Caltech provides a separate response area for each experience, so you’ll have 200 words for STEM Experience #1 and 200 words for STEM Experience #2.

Perhaps you experienced a fascinating challenge during your engineering internship, encountered a particularly thought-provoking topic during differential calculus, or relentlessly pursued an interest in black holes or topological physics. Whatever you choose—formal or informal, inside or outside the classroom—use this opportunity to share more about your chosen experience. What fascinated you about it, and why? How has it impacted you or enabled you to build particular skills?  Whether it’s falling down a Wikipedia rabbit hole about the nature of time or consuming thousands of hours of podcasts on drone capabilities, this is a chance to illustrate the ways in which you are an obsessive learner with an endless thirst for information.

The admissions reader should emerge from reading this essay with the sense that you are a sincerely curious young person with a strong intellectual drive. If that curiosity can be tied to your intended area of study at Caltech, all the better!

Caltech Essays – Prompt #4 (required)

The creativity, inventiveness, and innovation of Caltech’s students, faculty, and researchers have won  Nobel Prizes  and put  rovers on Mars . But Techers also imagine smaller scale innovations every day, from new ways to design solar cells to how to 3D print dorm decor. How have you been a creator, inventor, or innovator in your own life? (200-250 words)

Caltech knows you’re not a PhD-level researcher or a Nobel laureate, so they’re not looking for anything earth-shattering here (unless, of course, you’ve accomplished something earth-shattering—in which case, please share). Instead, they’re simply trying to understand the ways in which you bring your creative, inventive, and/or innovative qualities to your day-to-day life. Essentially, this is a fun chance to show off that side of yourself. To do so, feel free to go beyond extracurricular activities and formal experiences—maybe you perfected a solar oven design that bakes perfectly chewy chocolate chip cookies without utilizing electricity, or offered to develop a website for your local thrift shop with online shopping options. The sky is the limit here!

Caltech Supplemental Essays – Prompt #5 (required)

Caltech’s mission – to cultivate learning, discovery, and innovation for the benefit of humanity – relies on its community members embracing our Mission-Based Values ,  which include:

1. Openness and enthusiasm for having preconceptions challenged

2. Respect and appreciation for the idea that, while we are all members of the same community, the opportunities we’ve had to develop, showcase, and apply our talents have not been equal

3. Passion for the ideal that science can and should meaningfully improve the lives of others

Share what one or more of these values evokes for you. (200-400 words)

Here, Caltech provides you with three different values to choose from. Before you begin, make sure you familiarize yourself with Caltech’s full breakdown of their values . Then, choose one of the three noted above that 1) resonates most with you and 2) allows you to share more about your own personal experiences. Although you can select more than one, doing so may make it more difficult to craft a focused response, so keep that in mind as you write.

In addition, essays that wax poetic about the general importance of a chosen ideal—without connecting it to your own past experiences or future goals—will have approximately zero needle-moving value to the admissions committee. As such, rephrase each ideal as a question in order to identify the significance and depth of your associated experiences. For example, when have you had preconceptions challenged? How did you respond? When have you been confronted with the fact that yours (or your peers) opportunities have not been equal, and how did you handle it? Have you experienced how science can and should meaningfully improve the lives of others? How so?

Caltech Supplemental Essays – Prompt #6 & #7 (optional)

We know, we know … you see optional and start to wonder if we mean it. But in this section, we truly do! See these as completely optional opportunities to show us more of your personality. 

Optional. We promise.

• If there are aspects of your life or social or personal identity that you feel are not captured elsewhere in this application, please tell us about them below. (150 words)
• Did you have a hard time narrowing it down to just one interest or hobby? We understand – Caltech students like to stay busy, too – tell us about another hobby or interest! (50 words)

Caltech’s admissions committee is quite transparent about what they are and aren’t looking for, so this is one of those rare occasions when an optional essay is truly optional. As such, if there is something significant to share about your background, identity, or interests that hasn’t already been communicated elsewhere on the application, feel free to discuss it here, but do not feel compelled to respond if you’ll be grasping at straws to formulate an answer.

How important are the essays?

Overall, Caltech lists five factors as being “very important” to the admissions process. Those factors are: the rigor of your high school coursework, test scores (even though they are test blind, which is odd) recommendations, character/personal qualities, and your application essays. In fact, the essays are rated as being of greater importance than your GPA, class rank, or extracurricular activities!

In this guide, we will examine how things like the Caltech average GPA, the Caltech SAT scores, and the Caltech total enrollment impact the admissions process. We’ll also explain how to use the Caltech essays to show Caltech why you belong on their campus. 

In order to maximize your admissions odds, start preparing early. To submit a truly competitive application, start building your “how to get into Caltech” strategy well before the Caltech Early Action or regular Caltech application deadline. 

How hard is it to get into California Institute of Technology? 

According to U.S. News, Caltech is considered a highly competitive school with an acceptance rate of 7% . Just over 8,000 students applied for the Caltech Class of 2024. Of those applicants, the Caltech total enrollment was only 244 students. 

The Caltech average GPA ranges from 3.9 – 4.19. The average Caltech SAT scores range from 1530-1580. In the U.S. News 2022 edition of Best Colleges, the California Institute of Technology is ranked #9 in National Universities. 

If you want to know how to get into Caltech, you must understand that admission to this university is extremely competitive. Caltech would be a “reach” for any student. Becoming a Caltech Beaver will take much more than just meeting the Caltech average GPA or Caltech SAT scores. 

To increase your chances of admission, make sure to prepare your materials well before the Caltech Early Action or regular Caltech application deadline. Study for standardized tests, strive for a high GPA, and write genuine, thoughtful responses to the Caltech essays. Also, if you know that Caltech is your top choice, consider applying by the Caltech Early Action deadline. 

What is the average GPA for California Institute of Technology? 

Although there is no minimum GPA that will guarantee you admission to Caltech, most students should strive to maintain a GPA that aligns with the Caltech average GPA. The Caltech average GPA ranges from 3.9 – 4.19, meaning that most students had around a 4.0 GPA. 

Caltech will evaluate the GPA you earned by the end of your junior year. This means you should strive for high grades throughout high school, and that starts with choosing the right courses for you. Be sure to take advantage of all the resources available to you. This will give you a better chance of meeting the Caltech average GPA. 

Wondering how to get into Caltech with grades lower than the Caltech average GPA? Check out our blog article . You’ll find helpful tips on how to make your application stand out, even if you don’t meet the Caltech average GPA or Caltech SAT scores. 

What does the Caltech application look like? 

There are many parts to a Caltech application, but each one is essential to your “how to get into Caltech” strategy. Applicants are encouraged to submit all Caltech essays, optional test scores, and supplemental materials well before the Caltech Early Action or regular Caltech application deadline. 

The Caltech Early Action application deadline is November 1 st , and the Caltech application deadline for Regular Decision is January 3 rd . Caltech Early Action is non-binding, so if you apply under the Caltech Early Action deadline, you can still explore other options. 

Applicants must submit: 

• The Common Application or Coalition Application
• The Caltech essays , including three 250-word max responses
• An official transcript
• A school report
• Two teacher evaluations

An important part of your “how to get into Caltech” strategy is to compile all these materials well before the Caltech Early Action deadline or Regular Decision Caltech application deadline. The earlier you start strategizing, the stronger your application will be. 

Need some help acing the Common App? Read our guide here . 

Caltech introduced a test-optional policy due to the COVID-19 pandemic. However, we still suggest you submit high scores to maximize your admissions odds. 

Prospective applicants must submit three Caltech essays. These short-answer Caltech essays are designed to provide the admissions committee with a better understanding of who you are as a student, scientist, and person. We will also expand on the Caltech essays later in this guide. 

What extracurriculars do I need for California Institute of Technology? 

Want to know how to get into Caltech? Start by identifying your passions, interests, and talents. 

Extracurriculars contribute heavily to your candidate profile . Your candidate profile is a 1-2 sentence description of who you are, what you do, and why colleges should admit you. Having a strong candidate profile can set you apart from other applicants and is a crucial part of your “how to get into Caltech” plan. 

Caltech does not look for one specific extracurricular activity. Instead, Caltech wants to see that you are dedicated to your interests. So, it is more about the quality of your extracurriculars, rather than the quantity.  

Caltech also takes special note of any involvement in math or science extracurriculars. As a world-renowned science and engineering institute, Caltech wants students who naturally use math and science in different parts of their lives. Perhaps you co-founded a social club that solves physics problems for fun. Or, maybe one of your hobbies includes reading books about math theories and differential equations. Either way, try to highlight your intellectual curiosity about math and science in your Caltech application. 

What is the acceptance rate at Caltech? 

The Caltech acceptance rate is another key component to consider in your “how to get into Caltech” approach. Caltech has an acceptance rate of 7%, making it a highly selective school and ensuring that the Caltech total enrollment remains small. 

Caltech received just over 8,000 applications for the Class of 2024. Of those applicants, the Caltech total enrollment for the freshman class was 244 students. The Caltech total enrollment for each incoming class of students normally ranges between 235-240 students. That puts the Caltech total enrollment for the entire campus at fewer than 1,000 undergraduates. 

But what do acceptance rates mean, really? Acceptance rates come from the ratio of total applicants to accepted students. The Caltech acceptance rate varies each year and can be influenced by a variety of factors, like the Caltech total enrollment or standardized test scores.  

Although Caltech switched to a test-optional policy, we encourage you to take standardized tests if you can do so. The average Caltech SAT scores ranged from 1530-1580, and the average ACT score ranged from 35-36.  

In order to match the average Caltech SAT scores, start studying well before the Caltech Early Action or regular Caltech application deadline. Plan to take your first standardized test during your junior year. This gives you time to retake the tests if necessary so you can meet the average Caltech SAT scores.

Does California Institute of Technology require interviews?

As you strategize about how to get into Caltech, you might wonder if a Caltech interview is an option. Unfortunately, applicants are not offered a Caltech interview. 

In lieu of a Caltech interview, you should focus on securing strong teacher recommendations. This can show Caltech who you are in the classroom and help them envision you on their campus. Caltech requires two teacher recommendations—one from a math or science teacher, and one from a humanities or social sciences teacher. These teacher evaluations serve the same purpose as a Caltech interview—they help the admissions team learn more about you.

Beyond these two required teacher evaluations, you can also submit up to two additional evaluations from mentors or supervisors. These evaluations can also highlight your unique identity and interests, like what you would discuss in a Caltech interview. 

These additional evaluations should be from people who know you in a different context. For example, you could ask your former supervisor from a summer internship to write about your leadership skills and work ethic. Or, you could ask your youth pastor to describe your service efforts with your church. These evaluations can help you stand out from the crowd, much like a Caltech interview would. 

So, what should be included in these evaluations? Here are a few ideas: 

• Personal achievements (both inside the classroom and out)
• Extracurricular involvements
• Leadership experiences
• Interests and talents
• Special skills

Much like a Caltech interview would help the admissions committee learn more about you, these evaluations help Caltech see what you care about, what kind of student you are, and how you will contribute to their community.

How do I answer a Caltech essay? 

In addition to the main essay prompt found in the 2021-2022 Common App or Coalition App , the Caltech application requires three supplemental Caltech essays. All three supplemental Caltech essays have a maximum of 250-words.

Be sure to craft genuine, thoughtful responses to the Caltech essays. Additionally, if your GPA or test scores are just below the Caltech average GPA or Caltech SAT scores, the Caltech essays could be your chance to shine. We suggest you start writing the Caltech essays well before the Caltech application deadline. 

The first prompt:

This prompt asks about a time when you encountered failure. This essay is designed to assess your potential to overcome any obstacles you might face in the future. Anchor your response with details about how you showed resilience and persistence.

Here are some guiding questions from the Caltech website to help your brainstorming session: 

• How do you define failure? 
• What was the problem you were trying to solve? 
• What did you learn from the experience?

The second prompt:

The second of the three Caltech essays asks you to identify a subject that has inspired you to learn more about it. This prompt lets you show your intellectual curiosity and desire to learn new things. Here are the guiding questions for the second of the three supplemental Caltech essays: 

• What was the situation, story, or topic? 
• In which ways did it spike your curiosity? 
• How did the pursuit of a deeper, more focused understanding of this prove valuable or satisfying to you? 

The third prompt:

The last of the Caltech essays wants you to describe a time when you collaborated with your peers on a project or how you would do so once you join the Caltech community. This prompt seeks to understand your ability to work with others toward a common goal. Here are the guiding questions for the last of the Caltech essays: 

• What have your peers told you about the ways you contribute to working in groups? 
• How do you approach problem solving in groups? 
• What would your peers tell us about how you collaborate and work together with them?

Be sure to include specific details throughout your Caltech essays. The more detailed you are in your Caltech essays, the more likely it is that the admissions team will connect with you.

The Caltech essays are designed to assess who you are, apart from your academic transcript and test scores. So, use the Caltech essays to highlight what makes you unique. Finally, be sure to add how you will enrich life on campus in your Caltech essays.

How does Caltech review applications? 

When thinking about how to get into Caltech, many students only concern themselves with the Caltech average GPA, Caltech SAT scores, or Caltech total enrollment. Although these are important factors in the application process, there are other things to consider in your “how to get into Caltech” approach. 

Once the Caltech Early Action and regular Caltech application deadline have passed, Caltech begins the holistic review process. Each application is reviewed individually in order to determine a student’s strengths, experiences, perspectives, intellectual curiosity, and interests in science, engineering, and technology.  

Understandably, many prospective students have questions about how the COVID-19 pandemic will impact their college application. However, as the Caltech website suggests, Caltech wants students to take care of themselves and their communities first. As COVID-19 continues to impact the world, put yourself first—not your Caltech application.

Caltech is committed to reviewing students within the context of the opportunities and resources available to them. So, if your application falls short of the Caltech average GPA or Caltech SAT scores because of circumstances like the COVID-19 pandemic, Caltech will understand.

Contributing to community

It will take much more than just meeting the Caltech average GPA or Caltech SAT scores to perfect your “how to get into Caltech” strategy. As they review applications, admissions officers will also consider how each applicant might contribute to the Caltech community. 

Since the Caltech total enrollment is so low, Caltech cares deeply about who they admit. Caltech describes itself as a community that is “deeply immersed in inclusion, care, and collaboration.” So, use the Caltech essays to describe how you will exemplify these values as part of the Caltech community, in lieu of a Caltech interview. 

Spend time strengthening your academic achievements and extracurricular talents as you prepare your application. Additionally, be sure to craft your candidate profile well in advance of the Caltech application deadline, as this will help with your “how to get into Caltech” approach. 

Want more information about how to get into Caltech? Visit the Caltech website to read more about the holistic review process.

Will Caltech look at my social media?

As you think about how to get into Caltech, you might wonder if your social media presence could affect the admissions process. Rest assured, it is not likely that Caltech admissions officers will have the time or energy to review your social media accounts. 

However, this doesn’t mean that you can or should post offensive, disrespectful, or derogatory content on your social media. While these kinds of posts might not directly affect your application, there are plenty of other situations in which your social media accounts can impact your life. Many potential employers will review your social media presence when you apply for a job or internship with their company. 

Above all, we recommend using social media responsibly. Although it is not likely that Caltech will check your Instagram or Twitter accounts, there’s always a chance. 

Is Caltech a good school for me? 

As you research how to get into Caltech, it is important to reflect on whether Caltech is the right place for you. Yes, Caltech is ranked #9 in National Universities, and students who attend Caltech can pursue their STEM interests in a small academic community with a 3:1 student-faculty ratio. However, this doesn’t mean that Caltech is for everyone. 

As evidenced by the high Caltech average GPA, Caltech SAT scores, and low Caltech total enrollment, academics at Caltech are top-notch. Students begin their Caltech education with a core curriculum that ensures a strong foundation in mathematics and natural sciences. 

At Caltech, majors are referred to as an “option.” Students select an option towards the end of their freshman year. They then specialize in that option during their sophomore year and, finally, focus on their chosen field in their junior and senior years. 

As far as campus life, Caltech students can choose between 11 different residences that offer collaborative living and learning environments with unique traditions and pranks . One of the more well-known Caltech traditions involves sit-down dinners served by student waiters. 

As you are thinking about how to get into Caltech, ask yourself the following: 

• Am I interested in a small, STEM-oriented university?
• Does Caltech offer the major or “option” that I want to study?
• How can Caltech help me achieve my future goals? 

As you reflect on these questions, consider how your answers can help you craft stronger Caltech essays, as there is no Caltech interview option available. 

If you decide that Caltech is for you, you can either apply through Caltech Early Action or Regular Decision. Caltech Early Action admissions are non-binding. This means you can still explore other schools even if you get into Caltech. Either way, be sure to submit your materials well before the Caltech application deadline.

Finally, be sure to highlight your unique achievements and future goals —Caltech wants to know what kind of student you are and how you will add to the Caltech community. 

3. Don’t procrastinate

Don’t wait to apply—prepare your materials well in advance of the Caltech application deadline. You want to build the strongest application possible, so give yourself plenty of time to do so.

7. Seek Clarification if Needed:

If you have any doubts or uncertainties about the prompt, don't hesitate to seek clarification. Reach out to the admissions office or consult with your guidance counselor or teachers for guidance. It's better to have a clear understanding of the prompt before you start writing.

Understanding the prompts is essential because it allows you to focus your essay and provide a relevant and meaningful response.

B. Showcase Your Passion for Science and Technology: 

When writing an essay to showcase your passion for science and technology, it's important to demonstrate your genuine interest and enthusiasm in a compelling and impactful way. Here's how you can effectively showcase your passion for science and technology in your essay:

1. Personal Experiences:

Start by sharing personal experiences that ignited your passion for science and technology. Discuss a specific event, project, or moment that sparked your curiosity and enthusiasm. Explain how this experience influenced your desire to pursue studies in the field.

2. Academic Pursuits:

Illustrate your passion by highlighting your involvement in extracurricular activities related to science and technology. Discuss clubs, organizations, or initiatives where you actively participate and contribute.

If you are applying to Caltech, make connections between your passion and their specific programs, faculty, or resources. Research the school's unique offerings, such as research opportunities, collaborative projects, or renowned professors, and explain how these align with your interests and goals.

Remember to convey your passion for science and technology through vivid storytelling, engaging language, and personal anecdotes. Let your enthusiasm shine through in every aspect of your essay, from the introduction to the conclusion. By showcasing your authentic passion and dedication, you can make a compelling case for why you are an ideal candidate for further studies in science and technology.

C. Be Authentic: 

Being authentic in your college essay is crucial as it allows you to present your true self to the admissions committee. Here are some key points to consider when striving to be authentic in your writing:

1. Reflect on Your Values and Experiences:

Take the time to reflect on your values, beliefs, and experiences that have shaped your identity. Consider the moments, challenges, or accomplishments that have had a significant impact on you. These insights will help you convey your authentic self in your essay.

2. Share Personal Stories:

Use personal stories and anecdotes to bring your essay to life. Be open and honest about your experiences, emotions, and lessons learned. Sharing vulnerable moments can demonstrate your authenticity and allow the reader to connect with you on a deeper level.

3. Use Your Own Voice:

Write in a way that reflects your unique voice and personality. Avoid trying to mimic a particular writing style or using vocabulary that doesn't feel natural to you. Your essay should sound like you, conveying your thoughts and ideas in a genuine manner.

4. Express Your Passion and Enthusiasm:

Write about topics, interests, or activities that genuinely excite you. Showcasing your enthusiasm and genuine passion for your chosen field of study or extracurricular pursuits will help the reader understand your genuine interest and commitment.

5. Be Honest and Transparent:

Don't be tempted to exaggerate or fabricate experiences or accomplishments. Admissions officers can quickly identify inauthentic content, and it can harm your chances of admission. Instead, focus on presenting an honest and sincere representation of who you are.

6. Embrace Your Flaws and Failures:

It's important to acknowledge and embrace your flaws and failures as part of your authentic self. Admissions committees appreciate vulnerability and the ability to reflect on challenges and personal growth. Discuss how you've learned from setbacks and how they have contributed to your personal development.

7. Stay True to Your Values:

Your values shape who you are as a person. Ensure that your essay reflects your core values and beliefs. Discuss how these values have influenced your decisions, actions, and aspirations.

8. Seek Feedback from Others:

While it's essential to maintain your authentic voice, it can be helpful to seek feedback from trusted individuals, such as teachers, counselors, or mentors. They can provide insights and suggestions to help you refine your essay while ensuring that your authentic self shines through.

Being authentic in your college essay allows you to stand out and make a genuine connection with the admissions committee. By sharing your unique stories, expressing your true passions, and staying true to yourself, you can create a compelling and memorable essay that truly represents who you are as an individual.

D. Demonstrate Fit: 

Demonstrating fit in your college essay is about showing the admissions committee why you are a perfect match for their institution. Here's how you can effectively demonstrate fit in your writing:

1. Research the College:

Before writing your essay, thoroughly research the college or university you are applying to. Gain an understanding of its mission, values, academic programs, campus culture, and any unique opportunities it offers. This knowledge will help you tailor your essay to highlight the aspects that align with your interests and goals.

2. Connect Your Interests and Goals:

Clearly articulate how the college's offerings align with your academic and career aspirations. Explain why the specific academic programs, research opportunities, or extracurricular activities at the college resonate with your interests. This demonstrates your genuine enthusiasm and motivation to contribute to and benefit from the college's resources.

3. Showcase Shared Values:

Identify and emphasize the shared values between yourself and the college. If the institution emphasizes community engagement, social justice, or environmental sustainability, provide examples of your own experiences, projects, or initiatives that reflect these values. Showcasing alignment in values helps establish a strong connection between you and the college.

4. Mention Faculty and Resources:

Highlight specific professors, researchers, or resources at the college that are relevant to your intended field of study.

8. Convey Enthusiasm:

Throughout your essay, convey genuine enthusiasm and excitement about the college. Use descriptive language and specific examples to illustrate why you believe the college is the ideal place for you to learn, grow, and make a meaningful impact. Showcasing your enthusiasm will leave a positive impression on the admissions committee.

By effectively demonstrating fit in your essay, you can convince the admissions committee that you are not only a qualified applicant but also a perfect fit for their institution. Showcasing your understanding of the college's values, resources, and opportunities will help you stand out and increase your chances of admission.

E. Use Concrete Examples: 

Using concrete examples in your writing is an effective way to enhance the clarity, credibility, and impact of your essay. Here's how you can use concrete examples to strengthen your writing:

1. Provide Specific Details:

Instead of making general statements or using vague language, provide specific details and vivid descriptions. For example, instead of saying, "I had a challenging research experience," you can say, "During my summer internship at XYZ Research Institute, I conducted experiments on the effects of temperature variation on plant growth, collecting and analyzing data from over 100 samples."

2. Use Personal Anecdotes:

Share personal anecdotes or stories that support your points or illustrate your experiences. By providing real-life examples, you bring your writing to life and make it more relatable and engaging. These anecdotes can showcase your skills, achievements, challenges, or personal growth.

3. Quantify Achievements:

Whenever possible, use numbers, percentages, or statistics to quantify your achievements. For instance, instead of saying, "I contributed to increasing sales," you can say, "I implemented a marketing campaign that resulted in a 20% increase in sales within three months." Quantifying your accomplishments adds credibility and provides a clear picture of your impact.

4. Reference Specific Events or Experiences:

If you have participated in significant events, conferences, or competitions related to your field, mention them. Discuss your role, the outcomes, and how these experiences have shaped your perspective or skills. By referring to specific events, you demonstrate your active engagement and commitment to your area of interest.

5. Incorporate Research Findings or Studies:

When discussing academic topics or making arguments, support your statements with relevant research findings or studies. Cite reputable sources and provide specific details such as the authors, publication dates, or key findings. This shows that your arguments are grounded in evidence and adds credibility to your writing.

6. Draw from Personal Observations:

If you have observed real-world phenomena or trends that are relevant to your topic, share them in your essay. Provide specific examples of what you have observed, including the context, details, and any insights or conclusions you have drawn from these observations.

7. Discuss Relevant Projects or Assignments:

If you have completed noteworthy projects, assignments, or coursework, use them as concrete examples to support your claims or illustrate your abilities. Explain the objectives, methodologies, and outcomes of these projects, highlighting your skills, problem-solving abilities, or creativity.

8. Connect Examples to Your Overall Narrative:

Ensure that the examples you use align with the central theme or message of your essay. They should contribute to a coherent and compelling narrative that showcases your unique qualities, experiences, or perspectives.

By incorporating concrete examples into your writing, you provide tangible evidence of your experiences, skills, and achievements. This not only enhances the credibility of your essay but also helps the reader visualize your story and connect with your ideas on a deeper level. Remember to choose examples that are relevant, specific, and support the main points you are making in your essay.

Remember, the essay is an opportunity for the admissions committee to get to know you beyond your academic achievements. Use it as a platform to showcase your passions, values, and intellectual curiosity. Be confident in your abilities, be genuine, and let your personality shine through your essays.

The Admissions Strategist

How to write the caltech essays: the marvelous guide to success.

Located in Pasadena, California, the California Institute of Technology has an acceptance rate of 8% and is a world-renowned science and engineering institute with one of the nation’s lowest student-to-faculty ratios.

Despite its small size , Caltech’s contributions in science and research have led to international recognition, including 38 Nobel Prizes.

• The school also manages NASA’s Jet Propulsion Laboratory and owns and operates large-scale research facilities and a global network of astronomical observatories.

The self-stated mission of this private university is to “investigate the most challenging, fundamental problems in science and technology in a singularly collegial, interdisciplinary atmosphere, while educating outstanding students to become creative members of society.”

If this mission statement appeals to you, you might be a great fit for Caltech.

• But earning that acceptance letter isn’t easy: Caltech accepts only about 8% of applicants, building a freshman class of just 230 new students.

Luckily, we’re here to help with one of the most challenging parts of the application: the Caltech essays.

We’ll provide all the info and tips you need to write essays that will help you stand out from the competition.

Let’s get started!

What Are the Caltech Essay Requirements?

Caltech accepts both the Coalition Application and the Common Application , with no preference between the two platforms.

No matter which of these options you choose, you’ll also need to complete the Caltech Questions.

The university explains that these questions help them evaluate “your passion for science, technology, engineering, and math.” They’re looking to find out “what excites you, what you value, and which of Caltech’s resources appeal most to you.”

This supplement consists of four short answer questions:

The short answer questions are:

Describe three experiences and/or activities that have helped develop your passion for a possible career in a STEM field. Use the separate spaces provided below, one for each STEM experience and/or activity. (120 words for each activity?) Much like the life of a professional scientist or engineer, the life of a “Techer” relies heavily on collaboration. Knowing this, what do you hope to explore, innovate, or create with your Caltech peers? (Your response should range between 250-400 words.) Caltech students are often known for their sense of humor and creative pranks. What do you like to do for fun? (Your response should range between 250-400 words.) The process of discovery best advances when people from various backgrounds, experiences, and perspectives come together. How do you see yourself contributing to the diversity of Caltech’s community? (Your response should range between 250-400 words.)

What Kind of Student Does Caltech Want?

When applying to an extremely selective school like Caltech, it’s important to consider what type of student admissions officers are trying to find.

The goal here isn’t to lie and tell admissions officers what they want to hear; it’s to showcase the aspects of your personality and background that fit best with Caltech’s criteria.

On the university’s website, Caltech writes of freshman applicants, “All we ask is that you share the typical Caltech student’s unbridled sense of curiosity and extraordinary aptitude for and interest in science, engineering, and technology.”

They further explain that they attempt to answer several crucial questions as they review your application:

• Are you academically prepared?
• Have you demonstrated a consistent interest in science, technology, engineering, or math? (Are you ready to push the boundaries of scientific discovery?)
• How will you impact Caltech’s campus community?

Overall, the university is looking for students who not only excel in the STEM fields but are also passionate and excited about exploring these disciplines.

They want creative, curious students who can help make innovative contributions to society.

Caltech also values students who are collaborative and trustworthy enough to work with other Techers in classrooms and labs.

General Tips for the Caltech Essays

On the school website, Caltech explains that—perhaps surprisingly—the way they evaluate applications is “more of an art than a science.”

The admissions team reads every application and every essay to get a sense of who you are and determine whether you would be a good fit for Caltech, pointing out, “You are more than a GPA and a set of test scores!” The university’s advice is to take your time preparing the short answers and essays.

And taking the information in the previous section into consideration, we’ve come up with an additional list of general tips for responding to the Caltech Questions:

• Be authentic. Your genuine voice should shine through in these essays. Many students will be focused on trying to impress admissions officers rather than on providing honest answers, so one way to stand out is to simply be yourself!
• Be specific. Another way to write memorable essays is to provide specific, meaningful details . Don’t give the same general, generic answers that admissions officers will read over and over. The more specific you are, the more you’ll stand out.
• Be enthusiastic. One of Caltech’s key requirements is passion for science, technology, mathematics, and/or engineering. Show this excitement in your essays, and don’t be afraid to “geek out” a little. You should also demonstrate enthusiasm for learning and discovery.
• Be reflective. You might think it’s obvious how you’ll contribute at Caltech, but spell it out for admissions officers. Relate your responses to the contributions you’ll make in Caltech’s labs, classrooms, and community. Give specific examples of what you’ll do and how you’ll add value to the university.

Now that you know our general advice, let’s take a look at each of the questions you’ll be asked.

Get personalized advice!

Three experiences and activities.

Essay #1: Describe three experiences and/or activities that have helped develop your passion for a possible career in a STEM field. Use the separate spaces provided below, one for each STEM experience and/or activity.

First, note the key word “develop.”

• You should be writing about hands-on experiences with STEM, rather than passive activities like watching a video or observing an interesting lecture.
• Think of a time you applied your interest or passion in STEM.
• Consider projects, activities, research, and service. You have a broad range here, as long as you’re writing about your proactive approach to STEM.

Also keep in mind that you’re limited to only 120 words for each entry, meaning you don’t have much space to explore three experiences or activities in-depth. Your best bet is to write three short paragraphs, one for each of the events you’ve selected.

• It may be helpful to choose some activities that have been mentioned elsewhere in your application or essays. You won’t need to go too in-depth, which will save you some room.

This is a pretty straightforward question, so don’t pressure yourself to think outside the box or get too creative.

You could begin by brainstorming a list of hands-on experiences and activities you’ve had relating to STEM. Then choose your three favorites to write about.

A friendly heads-up: Don’t outsmart yourself for this question. You have three separate boxes for 120 words each, so get to the point, be concise, and choose practical, hands-on experiences. Don’t risk giving background detail or providing an activity that is passive or difficult to write about. Keep it simple.

The Life of a Techer: Collaboration

Essay #2: Much like the life of a professional scientist or engineer, the life of a “Techer” relies heavily on collaboration. Knowing this, what do you hope to explore, innovate, or create with your Caltech peers? (Your response should range between 250-400 words.)

Essentially, this is the “Why Caltech?” question. You can read our guide on how to write “Why This College” essays.

The best way to accomplish this goal is to do your research.

• Look into specific programs, extracurricular activities focused on STEM, classes, professors, and so on.
• If you feel the need to address any research opportunities, be sure to do so in extremely specific terms.
• What project are you extremely excited about? Which professor would you be working with?
• Why this project and professor in particular?
• Last, ask yourself how you can pursue these opportunities with fellow Techers.

Here’s how you should go about attacking this essay:

• Start by outlining your academic and career goals, as well as your specific area of interest in STEM.
• Then explain exactly how Caltech could help you further your interest and reach your goals.
• Discuss team dynamics and how you can leverage other students’ talents and experiences to accomplish your mission.
• Make sure you’re discussing opportunities and experiences unique to Caltech, rather than qualities that many other schools share as well.

It’s vital to be extremely enthusiastic in this essay.

Are you excited about Caltech? Excited enough to be one of just 230 students who receive this opportunity? Show it.

For example, here’s a successful outline of a Why Caltech essay:

• Your community was hit by a drought last year. It made you think about how communities in developing countries or those without infrastructure can survive such harsh climates.
• Your engineering team in high school designed a national irrigation system that adjusts the supply of water over a 300-mile mile radius. This irrigation system utilizes algorithms and radars to make its decisions.
• At Caltech, you want to work with research partners to discover how you can not only bring this irrigation system to life but also implement machine learning and AI to increase its deployment accuracy. Describe how you’ll work together.

Remember, never write about location or legacy. Southern California is a beautiful place, yes, but there are other schools in SoCal besides Caltech. Demonstrate that you took the time to research Caltech and how you fit within its community.

What Do You Do for Fun?

Essay #3: Caltech students are often known for their sense of humor and creative pranks. What do you like to do for fun? (Your response should range between 250-400 words.)

Think about your hobbies, possibly putting together another brainstorm list.

• What do you do in your spare time?
• List as many activities and interests as you can.
• Then, review the list for the most “unusual” way in which you have fun.

This doesn’t have to be something tremendously unique, just something unusual that not every teenager engages in.

• Avoid obviously common hobbies like reading, listening to music, playing video games, watching TV or movies, or playing sports (unless you play cricket, curling, or something else uncommon).
• Perhaps you collect Russian nesting dolls or build elaborate forts with your friends.
• Maybe you go on fun scavenger hunts around town or devote every Saturday to browsing yard sales for the best deals.

This isn’t a serious question and doesn’t require a serious or academic answer.

For this prompt, you do have enough room to vividly describe the unusual activity you enjoy.

Tell a story and include sensory details. If possible, you may want to see if there’s a way you can continue pursuing this unique activity at Caltech.

If not, maybe you would want to start a club of your own! Colleges love proactive students.

Irrespective of the hobby you choose, be sure to select one that has had a tangible effect on your life. Choose a hobby or pursuit that has changed you. Then, explain how it’s changed you.

• Do you train Brazilian jiujitsiu? Has it changed the way you approach competition and solve problems?
• Did you create an app for your school? What did you learn about solving a community’s problem using iOS or Android?

While it doesn’t need to be STEM-related, it should be substantive.

Contributingg to Diversity at Caltech

Essay #4: The process of discovery best advances when people from various backgrounds, experiences, and perspectives come together. How do you see yourself contributing to the diversity of Caltech’s community? (Your response should range between 250-400 words.

This question makes it clear that diversity comes in many forms. Diversity of experience, background, and thought are specifically mentioned, but you can think of any way that you might bring an interesting or unique perspective to Caltech.

• For instance, you might choose to write about your approach to solving and analyzing problems or generating ideas.
• How does your approach differ from others?
• What problems have you been able to solve, as a result, that others haven’t?
• And how could this help you contribute at Caltech?

You might also have a unique cultural or economic background, or experiences that you think will allow you to offer a fresh perspective at Caltech. There are many different ways to answer this question.

However you decide to approach the question, try to offer a supporting anecdote (a story that demonstrates the diversity you’ve mentioned) and explain how you’ll put this diverse perspective to use at Caltech.

Brainstorming the Caltech Essays

Here’s a helpful exercise that has helped a number of our students who have gone on to study at Caltech.

List three to seven books (titles and authors) that have been meaningful to you, each with a one-sentence summary of how that book has influenced you.

These don’t have to be math, science, or even academic texts.

• If you learned a valuable lesson from a fictional character or bonded with new friends over your love for a YA novel, feel free to include it here.
• You may want to include one book title that is in some way related to STEM. After all, your passion for science, math, and technology should be the focal point of your application.
• Lastly, we recommend avoiding any potentially controversial topics. You never know who will be reading your essays, and you don’t want to offend the person who holds your fate in their hands!

This exercise will help you broaden your thoughts and keep you from writing a cookie-cutter essay. Yes, it’s important to demonstrate your academic gravitas, but it’s also critical that you leverage other important aspects of your personality.

The books you’ve chosen for this list can demonstrate how you value knowledge and the interests you’re most likely to pursue once you’re in college.

Even if your interests are likely to change, this list will jog your memory and help you raise interesting points about yourself.

We mentioned above that Caltech values students who are trustworthy. The school is a close-knit, collaborative community, so honesty and integrity are vital. Here’s your opportunity to demonstrate that you possess these qualities.

• Come up with an ethical or moral dilemma to discuss.
• It doesn’t necessarily have to be a major problem, just a time you’ve had to make a challenging decision.
• Can you think of a time, possibly within your high school community, when you were faced with a tough choice, ultimately deciding to do the right thing?

Then, explain your problem-solving process, or how you arrived at a solution.

• Briefly introduce the problem and how you felt about the situation.
• Then, explain the factors you considered and the specific steps you took to arrive at a solution.

You don’t have many words to tell the story here, but try to include a few vivid details that can bring your experience to life. Show action. What did  you  do to solve the problem or come to a solution?

This is an unorthodox brainstorming exercise, but it will help you think three-dimensionally about your life and ability to create solutions. Creating solutions is, by definition, hands-on work, so this exercise is a good way to think critically about action steps you’ve taken to change your life or someone else’s.

How to Get Into Caltech

Padya Paramita

September 29, 2020

If you’re a student who is passionate about STEM and looking at competitive colleges, you likely have your eye on the California Institute of Technology (Caltech). Consistently ranked among the top universities every year — and undoubtedly one of the best for STEM — this Pasadena school provides coveted research opportunities and individualized mentorships for aspiring scientists and researchers. Now, you may be wondering how to get into Caltech....

Well, it’s easier said than done!

With an acceptance rate of only 6.4%, Caltech is extremely selective. To guide you through the question of how to get into Caltech , I’ve elaborated on Caltech’s academic programs, the academic requirements, understanding the recent test blind policy, how to take advantage of your extracurriculars, ways to write your essays, and finally, the requirements and deadlines as set by the school.

The Undergraduate Student Population

Caltech’s low acceptance rate is intensified by the fact that it has a total undergraduate population of only 938 students. Unlike the other most prestigious STEM-centered, MIT, which has over 4,000 undergraduates, Caltech is far smaller. The class of 2024 only has 244 students! This is smaller than most high school classes or even liberal arts colleges. This should give you a sense of exactly how difficult it is to get into Caltech.  In order to vie for one of these coveted spots, you have to work extremely hard. This means demonstrating a strong interest in Caltech alongside building a stellar academic and extracurricular profile, with an emphasis in the sciences.  

The Caltech Academic Programs

If you’re looking up how to get into Caltech, chances are, you’re interested in the sciences. But, you’ve got to be more specific than just a general interest in STEM — you need to be highly specific in your interests and goals.

The Caltech majors are divided into 6 divisions: Biology, Chemistry, Engineering and Applied Science, Geological and Planetary Sciences, Humanities and Social Sciences, and finally, Physics, Mathematics, and Astronomy. Students can choose from a variety of specialized concentrations such as “Business, Economics, & Management,” “Geobiology,” and “History and Philosophy and Science.” If you’re a STEM-focused student who is still curious about other topics, courses in the Humanities and Social Sciences division can be your go-to for an interdisciplinary approach to your interests. 

When you apply to Caltech on the Common App, you’ll need to indicate two majors that you’re most likely to declare. Think carefully about your choices, and make sure that you’ve worked hard in those areas so that admissions officers understand why you’ve chosen them.

Test Blind Policy

In June 2020, Caltech enacted a two-year moratorium on both the requirement and consideration of SAT and/or ACT test scores as part of the undergraduate admissions process. As of July 2021, the original two-year moratorium was extended an additional third year. This means that the school will not even look at your test scores if you submit them. This decision, made as a result of test cancelations due to the outbreak of COVID-19, has come as a shock to many; historically, Caltech is near the top of the list of highest SAT median scores. Applicants to this university bring impressive numbers, showcasing their academic prowess — particularly in math — for decades.

For applicants hoping to get accepted, the rest of your academic profile matters more than ever.  

Academic Requirements

The average GPA of accepted students at Caltech is 4.0. So, if you know from an early age that you’ll be curious about how to get into Caltech , you’ll have to work extremely hard.

Even though standardized tests are no longer in the picture, Caltech’s standards are still incredibly high. They expect students to excel in their courses throughout high school. To get into a school as competitive as Caltech, you must challenge yourself by taking the most difficult courses available to you. Caltech will look at your school context, but the website states , “Students are not compared to one another, even if they come from the same high school, because each student has a different set of life circumstances.” So it’s not about whether you’ve sought out the most challenging courses in the entire country, but rather that you’ve taken the ones available at your school, whether that’s AP BC Calculus or IB Advanced Math.

Example Coursework

In our experience, students who get accepted to Caltech have taken advanced coursework in both math and science. This means taking AP Calc BC at minimum, and in many cases (when available), taking more advanced courses like Multivariable Calculus, Linear Algebra, or even advanced seminars. When these classes have not been readily available to our talented math students in high school, we’ve encouraged them to enroll in local community colleges. For science, this means taking AP Physics 1 at minimum, but in most cases, taking AP Physics C and beyond.

Letters of Recommendation

The university highly values your teacher recommendations . Since these letters provide the reader with an idea of what you’re like in the classroom, you must choose instructors who know you well. 

Some of the best people to ask are:

• Teachers who have known you the longest
• Teachers you’ve had more recently
• Teachers you’ve worked  most closely with
• Teacher with whom you’ve worked with in an extracurricular setting, such as your debate team coach or dance teacher
• Teachers who taught the subjects that align with your goals and interests
• Teachers with connections to one of your top-choice colleges

Especially now that the school is test blind, the reader will carefully evaluate these letters to understand what it’s like to have you in the classroom. If you’ve got Caltech in mind, note that one of your recommendation letters must come from a math or science teacher. The other should come from a humanities or social sciences teacher. So, don’t just work hard in your science classes or get to know your math teacher. Your humanities teachers should also know you well enough to provide you with a glowing letter. 

Academic Research

Since Caltech is a big research university, you should also be seeking research opportunities — or initiating your own — in a field of your interest. This could entail participating in a research-based summer program such as:

• Research Science Institute
• Simons Summer Research Program
• Aspirnaut Summer Research Internships for High School Students  
• Boston University – Research in Science & Engineering (RISE)
• Children's Hospital Colorado Child Health Research Internship
• Garcia Scholars – Stony Brook University
• Maine Space Grant Consortium Research Internships for Teachers and Students (MERITS)
• Magee Women's Research Institute High School Summer Internship Program
• National Institutes of Health – Summer Internship in Biomedical Research (SIP)
• Naval Research Laboratory Science and Engineering Apprenticeship Program  
• Stanford Institutes of Medicine Summer Research Program (SIMR)
• University of California-Santa Barbara Research Mentorship Program  
• University of Chicago Research in the Biological Sciences (RIBS)

Another option is conducting your own research project. While not particularly uncommon, admissions officers appreciate students who pursue this route, as it showcases initiative and independence. A teacher from your school may help guide you and provide you with the resources you need.

Extracurricular Activities

Caltech wants to know whether you have demonstrated a consistent interest in science, technology, engineering, or math, not just through your classes, but also through your extracurricular activities. This means striving for leadership positions in your STEM-related activities.

Caltech is home to over 100 student organizations in academics, arts, hobbies, outdoors, politics, activism, community service, and more. Since almost every student will have involvements in STEM, as you build your extracurricular profile when researching how to get into Caltech, you should be working to find a nuanced angle to each of them. For example, you’re interested in both physics and gender studies, you can combine the two to work on a research project on the importance of female physicists.

Competitions

Building a profile in STEM can mean participating and performing well in esteemed STEM competitions such as:

• Intel International Science and Engineering Fair (ISEF)
• Regeneron Science Talent Search (STS)
• Davidson Fellows Scholarship
• Google Code Jam / Facebook Hacker Cup
• International Genetically Engineered Machines (iGEMS)
• Harvard MIT Mathematics Tournament
• American Invitational Mathematics Exam (AIME)
• International Mathematical Olympiad

Depending where your interest lies, seek out competitions that can help demonstrate your skills in your choice of field. 

Summer Programs

Many students also enroll in competitive summer programs to enhance their knowledge in the sciences, learn under esteemed professors from top universities, and conduct their own research projects. Some of the most prestigious STEM camps include:

• Engineering Summer Academy at Penn (ESAP) 
• MIT Minority Introduction to Engineering and Science (MITES)
• Ohio State University Ross Math Project
• Penn Medical School Summer Program
• Stanford University Math Summer Camp (SUMaC)
• The California State Summer School for Mathematics & Science (COSMOS)
• Yale Biological & Biomedical Sciences
• Yale Summer Astrophysics Project 

Showcasing participation in such competitions and programs in your activities list can boost your application and exemplify how your interest in a specific STEM topic expands beyond just on paper.

Personal Statement

Your love for your field of choice should extend beyond just your activities list. If science is a big part of your life — or there’s a story that makes you unique — tell the admissions office through your Common App personal statement . Even though this essay isn’t Caltech specific, you can use your response to showcase who you are and help the admissions officers gauge what you can bring to the campus that no other student can. 

Even though you can’t rave about Caltech in this part of the application, the prompts still provide you with a chance to tell a story that doesn’t apply to 99% of other students. So, your response could also focus on a part of your background that has shaped you or it could highlight an experience that you believe distinguishes you from your peers. You must brainstorm your essay very carefully, as well as go through at least ten drafts in order to submit a polished version of Caltech’s caliber.

Supplemental Essays

As a prospective “Techer,” you’ll also have to write Caltech-specific essays to highlight your interest in the school as well as elaborate further on your interests, especially within STEM. The four questions you need to answer are outlined below:

• Describe three experiences and/or activities that have helped develop your passion for a possible career in a STEM field. (10-120 words each)
• Much like the life of a professional scientist or engineer, the life of a "Techer" relies heavily on collaboration. Knowing this, what do you hope to explore, innovate, or create with your Caltech peers? (250-400 words)
• Caltech students are often known for their sense of humor and creative pranks. What do you like to do for fun? (250-400 words)
• The process of discovery best advances when people from various backgrounds, experiences, and perspectives come together. How do you see yourself contributing to the diversity of Caltech's community? (Your response should range between 250-400 words)

Explore the Caltech website before sitting down to write your responses. You need to know what makes the school unique and which resources call out to you the most, whether it’s the Human Health Research Center or the Summer Undergraduate Research Fellowships (SURF). This knowledge will come in handy when writing your essays, as you’ll demonstrate knowledge of programs and opportunities at this prestigious institution. You must also make sure that each of your answers adds new information about you. Use every prompt as an opportunity to tell the admissions office something new. Never repeat content! Let your essays add depth to your application, and convince the reader more and more that you could be a good fit for Caltech.

And of course, be specific with your interests. Caltech admissions officers read thousands of applications every year. You need to make sure that you’ve conveyed why your interests — whether your experiences and activities, or your idea of a humorous or creative prank — are exceptional. Think carefully before writing the answers. You can learn more about how to tackle each question in our blog about the Caltech supplemental essays .

Requirements and Deadlines

When thinking about how to get into Caltech , you must also consider the logistics. It’s extremely important that you follow instructions and stick to deadlines when it comes to getting the required scores, recommendations, and other documents submitted on time.

The Early Action (EA) deadline for Caltech is November 1 , while the Regular Decision deadline is January 3 . 

Knowing these dates can help you start working on the Common App, writing all of the required essays, and providing your recommenders enough time to write their letters. Everything you need to submit for your Caltech undergraduate application is outlined in the table below:

Use the table as a checklist to make sure you send all of the necessary documents and scores. Once you’ve submitted your application, Early Action applicants are notified in mid-December, while Regular Decision applicants are notified by mid-March. 

While it’s certainly difficult, conquering the question of how to get into Caltech is not impossible. You’ve got to work hard to demonstrate not just excellence in your academics but also in your extracurriculars. Plus, you must show admissions specific reasons for why you are a strong fit for their university. Research the school thoroughly before putting your application together and hopefully you’ll put yourself at a strong position to vie for one of these highly coveted spots. Good luck!

Former Admissions Committee Member, Columbia University

Reviewed: 1/18/24

As a world-renowned science and engineering institution, the California Institute of Technology (Caltech) is a popular addition to college lists nationwide. Read on to learn more about standing out in the admissions process and how to get into Caltech! 

Caltech, established in 1891 , is a prestigious school popular among students hoping to make their mark in science or engineering. If you're interested in attending Caltech's 124-acre campus in Pasadena, you'll need to perfect your college application for the best chance of acceptance. 

We'll walk you through everything you need to know about how to get into Caltech , including a step-by-step guide, how hard it is to get accepted, and the benefits of attending. 

Caltech Acceptance Rate: 3.1%

The CIT acceptance rate is about 3.1% . This rate reflects Caltech’s prestige and means students have to bring their absolute A-games to their applications! 

Data shows that Caltech received 13,136 applications in the most recent admissions cycle, but only 412 students were offered admission . Of this percentage, only 263 matriculated . 

The Caltech deferral rate is similarly quite low. While they don’t provide a specific percentage, they do state that they’re very selective with the applicants they choose to defer from Restrictive Early Action. 

To give you more insight into the Caltech acceptance rate, here are some admissions trends from the past few years:

Caltech Restrictive Early Action Acceptance Rate: <5%

Caltech offers a Restrictive Early Action plan, rather than a simple EA or ED process. Their REA acceptance rate is roughly the same as their overall rate, at less than 5%. 

Caltech does not commonly release early action acceptance data, but their website states that both their EA and RD admit rates are under 5% , with a negligible difference. From this info, we can assume that the EA acceptance rate sits around 3%. 

How Hard Is It to Get Into Caltech? 

With an acceptance rate of 3.1%, Caltech is an extremely selective school. You’ll need high SAT/ACT scores , a strong application with an outstanding essay, and stellar letters of recommendation to get in. 

The school’s prestige plays a part in this. According to U.S. News World and Report, Caltech is ranked as the No. 7 Best National University . Given its ranking based on outcomes, faculty resources, expert opinion, and more, it’s no wonder that Caltech is considered a highly selective school. 

Take our interactive quiz below to find out how likely you are to get into Caltech .

Caltech Essay Prompts

Caltech asks all first-year applicants to respond to several supplemental essay prompts : one academic question, three short answers, and a few optional short answers. 

Academic Question

If you had to choose an area of interest or two today, what would you choose? Why did you choose that area of interest? (200-word limit)

Required Short Answers

1. At Caltech, we investigate some of the most challenging, fundamental problems in science, technology, engineering, and mathematics. Identify and describe two STEM-related experiences from your high school years, either in or out of the classroom, and tell us how and why they activated your curiosity. What about them made you want to learn more and explore further? (Min: 100/Max: 200 words for each experience)

2. The creativity, inventiveness, and innovation of Caltech's students, faculty, and researchers have won Nobel Prizes and put rovers on Mars . But Techers also imagine smaller-scale innovations every day, from new ways to design solar cells to how to 3D print dorm decor. How have you been a creator, inventor, or innovator in your own life? (Min: 200 / Max: 250)

3. Caltech's mission – to cultivate learning, discovery, and innovation for the benefit of humanity – relies on its community members embracing fundamental Caltech values :

• Openness and enthusiasm for having preconceptions challenged
• Respect and appreciation for the idea that, while we are all members of the same community, the opportunities we've had to develop, showcase, and apply our talents have not been equal
• Passion for the ideal that science can and should meaningfully improve the lives of others

Share what one or more of these values evokes for you. (Min: 200 / Max: 400)

Optional Short Answers

1. If there are aspects of your life or social or personal identity that you feel are not captured elsewhere in this application, please tell us about them below. (Max: 150 words)

2. When not surveying the stars, peering through microscopes, or running through marathons of coding, Caltech students pursue an eclectic array of interests that range from speed-cubing to participating in varsity athletics to reading romance novels. What is a favorite interest or hobby, and why does it bring you joy? (Max: 100 words)

3. Did you have a hard time narrowing it down to just one interest or hobby? We understand – Caltech students like to stay busy, too – tell us about another hobby or interest! (Max: 50 words)

Optional Academic Short Answers 

1. Have you had any extenuating circumstances (such as limited course selection or disruptions), that have affected your coursework, but that are not described elsewhere in your application? If so, tell us about them here.

2. Some Caltech applicants engage in STEM competitions locally, nationally, or internationally (eg., AIME, Science Olympiad, International Science Olympiads). If you have received any STEM honors or awards, list them here (with scores, if applicable).

Crafting thoughtful essays is key to getting into Caltech's undergrad program. Ensure you spend time brainstorming, outlining, and editing your responses before submitting them. Remember to keep your writing concise: you don't have many words to get your main idea across! 

FAQs: How to Get Into Caltech

Do you still have questions about how to get into Caltech? Let these FAQs be your guide! 

1. Will Caltech Consider My SAT/ACT Scores? 

Caltech will not require or consider any SAT or ACT scores until at least fall 2025. 

2. Can Anyone Set Up Caltech’s ISP Curricula?

To set up Caltech’s ISP curricula for yourself, these two criteria must be met: 

• “The program must enable educational goals that cannot be achieved in any of the other available Options.
• In scope and depth, the program must be comparable to a normal undergraduate program.” 

3. Do I Have a Better Chance of Getting Into Caltech With Restrictive Early Action? 

It depends. While Early Action/Early Decision pathways generally have higher acceptance rates at top colleges, this is usually because students have worked hard to have their applications perfected. 

Applying to Caltech through REA won’t make much of a difference from Regular Decision if your application is not polished enough! You know how hard it is to get into Caltech, but a well-executed application can make all the difference. 

4. How Do I Get Into Caltech as a Homeschooled Student? 

Many homeschooled applicants are curious about how to get into Caltech undergrad programs. The Caltech admissions committee does not require any additional application materials from homeschooled students than it does from their traditionally educated peers. Caltech reviews each applicant within the context of their experiences. 

5. I Am Not In the Top 10% Of My Class. What Are My Chances of Acceptance? 

Almost all students admitted to Caltech are in the top 10% of their graduating class. This means that only 1% of admitted first-year students are not in the top 10%. 

6. What Classes Should I Take to Get Into Caltech? 

It would be best to take the most challenging curriculum available to you, especially in your STEM subjects. Caltech admits students who challenge themselves and show they're ready for a rigorous, STEM-based curriculum. 

7. How Do I Get Into Caltech As a Transfer Student?

If you’re wondering how difficult it is to get into Caltech as a transfer student , it’s even more challenging than regular admissions. You’ll need to maintain high grades at your current college, particularly in STEM coursework, as you’ll be required to write entrance exams on the following topics: 

• Calculus of One and Several Variables
• Linear Algebra
• Differential Equations
• Classical Mechanics and Electromagnetism
• Waves, Quantum Mechanics, and Statistical Physics

You should also have strong supplemental essays that share how you explore STEM outside of the classroom!

8. How Much Is the Tuition Fee At Caltech?

So, you’re ready to reap all the benefits this school has to offer and start your application, but how much will it cost to go to the California Institute of Technology? Caltech’s tuition costs $63,402 a year. On top of your other college expenses, it’s estimated you’ll spend between $80,000 to $90,000 a year to attend this school. 

If this cost is too steep for you, consider looking into financial aid options. 

9. Does Caltech Do Interviews? 

No, Caltech does not offer admission interviews as part of the application process. This means that you’ll need to give the admission committee a very good sense of who you are through your supplemental essays and other application materials. 

Final Thoughts

Now that you know more about the admissions process and how to get into Caltech, you can take the appropriate steps to give yourself the best chance of acceptance. 

While getting into Caltech’s undergraduate program is difficult, taking challenging courses, writing well-crafted essays, and securing stellar recommendations will boost your chances of acceptance. With patience and hard work, you can make your dreams of attending Caltech a reality!

How to Improve Your Chances of Getting into Caltech

1. achieve a high gpa while taking the most challenging classes available.

Because Caltech is extremely selective, it’s imperative for your academic credentials to be strong. Like other colleges of its caliber, the university uses the Academic Index to filter out candidates. That means that they will only look at the more qualitative aspects of your application if you meet their minimum academic threshold.

And it’s not just about the number values. Caltech also wants to see students taking a challenging curriculum. That means plenty of honors and AP/IB courses, particularly in your area of specialization.

If your GPA is lower, and you’re earlier on in your high school career, check out our tips for increasing your GPA . If you’re a junior or senior, it will be harder to increase your GPA.

2. Cultivate at least one or two Tier 1-2 extracurriculars (find your “spike”)

Caltech evaluates activities based on 4 Tiers of Extracurriculars , with Tier 1 indicating activities that are highly specialized and exceptional and Tier 4 indicating activities that are commonly found on students’ applications. (Check out these impressive ECs for college .)

It’s best to have one or two well-developed interests, as opposed to a plethora of interests and smattering of different activities. Instead, try to cultivate your passions and show at least a couple Tier 1-2 activities, such as placing in a national science competition or publishing research as a high school student.

3. Have a strong math and science background

Although the school has many choices of programs, Caltech is primarily a STEM institution. Regardless of your major, you will graduate with a Bachelor of Science.

That means you need to demonstrate a strong math and science background. Take challenging courses in subjects like Calculus, Statistics, Chemistry, Computer Science, and so on — depending on what’s available to you — and show preparation in other ways, such as through extracurricular activities in these areas.

4. Write engaging essays

Most students who apply to Caltech have strong academic credentials. To set yourself apart, you need to show skills in qualitative aspects of your application, too. Essays are one way to do this.

This year, Caltech has the following prompts:

• Tell us about a time or experience in which you encountered failure.
• Tell us about a life situation, media story, or topic – beyond or outside of a classroom or formal assignment – that has captivated you, inspired your curiosity, and led you to delve more deeply into learning about a subject on your own.

These essays are opportunities to demonstrate your own voice and personality, giving the adcom insight into who you really are and what you value. See our advice for writing the Caltech essays in the 2021–22 year .

5. Apply Early Action/Early Decision

Caltech offers a non-binding, non-restrictive Early Action plan, meaning you can apply earlier than Regular Decision and not be required to attend the university if accepted and can also apply to other schools EA.

While Caltech doesn’t publish its EA acceptance rate, students usually have a slight advantage applying under this plan at other schools, although not as much as they do with an Early Decision plan. Given that EA is neither binding nor restrictive, there are few downsides to choosing this plan.

6. Develop relationships with teachers and secure strong recommendations

Caltech considers teacher recommendations “very important.” That means you should be working on cultivating relationships with your teachers early on in your academic career, although usually, you’ll want to ask those who taught you later in high school. You’ll also want to spend some time considering who really knows you the best and can attest to your character, as well as your academic abilities.

Note that Caltech requires two letters of evaluation, including one from a math or science teacher and one from a humanities or social sciences teacher. Get some tips on how to ask for recommendations .

Career Advising

Career Services: Beyond Resume and Interview Prep

May 01, 2024

Marisa Demers

Caltech is changing how it connects students to meaningful careers, and a gift from Philip (BS ’76) and Nancy Naecker is putting these efforts on the fast track.

A gift from alumnus, mentor, and information technology executive Philip Naecker (BS ’76) and his wife, Nancy Naecker, is helping to transform career development at Caltech. The couple’s generosity, which provides no-strings-attached support, frees Caltech leaders to experiment with holistic career services and identify ways to amplify alumni engagement in the process.

Phil Naecker hopes the impact will extend beyond today’s students.

“We are facing some deep challenges, from poverty to healthcare to the future of the planet,” Naecker says. “These are complex issues with millions of smaller problems embedded in them. If connected to the right job opportunities, Caltech students are exceptionally well positioned to make the impact the world needs.”

Students across all six academic divisions are already benefiting from the Phil and Nancy Naecker IST Fund for Student Success, which is co-managed by the Career Achievement, Leadership, and Exploration (CALE) office and Caltech’s Information Science and Technology (IST) initiative. The Naeckers’ gift has been used to establish an alumni mentorship program for student interns, a collection of oral histories highlighting alumni career journeys, and a career exploration course taught by life coach Anna Resnick (BS ’19) that taps into the principles of design thinking.

The End of Imposter Syndrome

Naecker, who lives near campus, has maintained strong ties with the Caltech community since graduation. He has served on the boards of the Caltech Y, the Caltech Alumni Association , and the Caltech Gnome Club. The Naeckers are also members of the Caltech Associates .

Over the past decade, Phil Naecker has focused his attention on Caltech students and their success after graduation. Many Techers do exceptionally well when they leave Caltech, he says, but some stumble over preventable mistakes. For example, he has seen imposter syndrome get the better of undergraduates who omitted significant accomplishments—such as serving as author on a published academic paper or designing software that flew on a JPL mission to measure the cosmic microwave background radiation—during the application process. Even after mastering job-search mechanics, many others have broader questions about career paths, changing fields, and becoming leaders.

“A Caltech education is well suited to meeting the needs of the modern world,” Naecker says. “Once they leave campus, Techers quickly find themselves rising to leadership roles and migrating to careers outside of their majors. I’m glad this gift has already created more opportunities for alumni and students to come together and to enable Caltech graduates to approach their job searches with greater confidence, creativity, and success."

It Took One Phone Call

Naecker’s personal experience attests to the powerful and positive impact alumni can have on students and their careers. When he was nearing the end of his senior year at Caltech in 1976, Naecker had a change of heart about his post-graduation plans. The out-of-state graduate programs that accepted him had become less desirable to the Texas native since he met Nancy, a nursing student at Cal State Los Angeles. He wanted to stay in Pasadena, but he needed a job.

He explained his situation to Jim Black, former executive director of the Caltech Alumni Association, who called alumni William Carroll (BS ’48, MS ’49) and John Fee (BS ’51) and asked if they had any openings at their firm, James M. Montgomery Consulting Engineers. The job was Naecker’s before he left the interview.

For the next 10 years, Naecker worked at Montgomery, helping to clean the nation’s waterways and provide safe drinking water to millions of Americans. Carroll and Fee continued to serve as mentors.

When he was in his 30s, Naecker decided to change course and pursue a career in computing and information technology. He recently retired as chief technology officer for a quantitative finance firm.

A Holistic Approach to Career Services

Claire Ralph met Naecker in 2016, when she was in charge of outreach and partnerships for the Department of Computing + Mathematical Sciences (CMS). Together, they created CMS Mentoring Days , a series of speed-mentoring events for students in the department. Now in its eighth year, the program has expanded to serve students in electrical engineering and finance as well.

In 2019, Ralph was appointed director of the Career Development Center and oversaw its name change to CALE, reflecting its enhanced mission of fostering self-discovery, meaningful connections, and leadership development. She continues to bounce ideas off Naecker as she explores new ways to serve students. “Caltech has the honor of teaching these incredible minds,” Ralph says, “and it’s our responsibility to make sure they graduate feeling supported and confident about their next steps in life.”

Naecker agrees and hopes his gift will encourage other alumni to connect with students.

“A small amount of effort from alumni provides a huge payoff for students,” Naecker says. “It’s a rewarding experience, and, in some ways, it’s a full-circle moment because we get the opportunity to help our former selves!”

Let us know what the Caltech student experience means to you.

Admitted Students Discover Caltech

Each spring, Caltech invites newly admitted students to campus to see for themselves what makes the Institute's unique community worth joining. For three days, students and their family members participate in a range of events, panels, tours, and activities to learn more about the Caltech experience. This year, 207 students (out of 315 total admitted students) attended the event, known as Discover Caltech (DiscoTech), collecting data to inform their college-decision process while also making friends and building community.

In addition to DiscoTech, students from historically excluded or underrepresented backgrounds were invited to a one-day pre-program, ecosySTEMs, to learn more about support systems and to make connections with their peers.

At a welcome ceremony for all attendees, Ashley Pallie, Caltech's executive director of undergraduate admissions and chief admissions officer, encouraged students to "take measure of that gut feeling" throughout their experience at DiscoTech. Alum Kevin Noertker (BS '09) delivered a keynote address, discussing his experience of being admitted to and attending Caltech, and relaying the story how he later co-founded Ampaire, an electric aircraft company. He advised students to embrace their "core values" and dared them to "make bold choices." He added: "It is an opportunity each of us have in this world to do great things."

Admitted students toured campus and participated in division open houses and lab tours. They also got to listen to academic lectures from faculty members, getting a taste of the first-year class experience.

During an event called "Exploring L.A. & the Stars: An Evening at Griffith Observatory," students visited the iconic landmark and heard a lecture from Mike Brown, the Richard and Barbara Rosenberg Professor of Planetary Astronomy.

At the club fair, admitted students had the chance to meet current undergraduates and learn about different ways to get involved on campus, such as the Caltech Racing Club (which designs and builds race cars), the Black Student Union, and the Caltech QuestBridge Scholars Network.

On the evening of the final full day at DiscoTech, admitted students joined house dinners with current students and participated in social events organized by the houses, including a concert at Ricketts House, and cookie decorating, lock picking, and painting activities at Blacker House. Admitted students also had the opportunity to spend the night in Caltech housing, sharing dorm rooms with current students in a fully immersive experience.

The last formal event for DiscoTech was a bottle rocket launch competition held in an athletic field on campus. Students were split into teams and given materials to build a pressure-powered bottle rocket, including plastic bottles, string, duct tape, plastic bags, and water. The winning team (pictured) launched their bottle into the air for the longest amount of time, around five seconds, and won specially designed DiscoTech jerseys.

Admitted students have until May 1 to commit to attending Caltech.
