Supplemental 3/2 Application Essays

When you apply to Caltech, you will be required to submit supplemental application essays. These essays are an opportunity to tell us about yourself in your unique voice. There are no right or wrong answers but we do have some advice:

• Remember, Caltech is an unapologetic STEM institution. Literally, there is no way to write about too much STEM in your supplemental questions. So lean all the way in on the STEMiest of STEMmy topics (yep, those are made-up words but totally appropriate). Review our What We Look For page before you get started.
• Faculty at Caltech review files of the most competitive applicants. So don't worry that your science won't make sense to a lay-person because our faculty with PhDs conducting research that will change the world will understand what you're saying. We promise.
• If there is anything important about who you are, what you've done, or how you've experienced your life - we want to know about it. Holistic review means whole person review. We're here for whatever you want to share.
• We don't want essay writing to be intimidating, but we know it often is. We have put together some advice to help you get started writing your Caltech supplemental essays, so you can worry less and enjoy the application process.

All Fall 2024 applicants will be asked to review Caltech's guidelines on the ethical use of AI before submitting their supplemental essays.

Required Academic Question

3/2 students declare their majors by the start of their first term at Caltech, after which they take major specific courses. Dual degrees cannot be in the same major unless the programs differ substantially.

If you had to choose a major today, what would you choose? Why do you think Caltech is the right place to pursue this interest? Why did you choose that area of interest? (Max: 200 words)

Required Educational Background Question

Why do you want to continue your studies through the 3/2 program at Caltech? What are you hoping to accomplish that you cannot do at your current institution? (Min: 200/Max: 400 words)

Required Short Answer Questions

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 the last three 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

Optional Short Answer Questions

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.

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 Answer Questions

OPTIONAL: 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.

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).
