The school also prioritizes a collaborative spirit. Just consider one of its essay prompts:

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.

• Tell us about how you have collaborated with and worked together within a small group of your peers on some task or endeavor in the past, or about how you imagine you will work with your Caltech peers in the future.

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.
