Why Study at Caltech?

Pure Science Focus

Caltech is for those who love science for science's sake. It offers a rigorous "Core Curriculum" that ensures every student masters math, physics, and chemistry.

Tiny & Tight-Knit

With fewer than 1,000 undergraduates, Caltech offers an intimate community where you will know almost everyone and have direct access to professors.

NASA Partnership

Caltech manages JPL for NASA. Students have unique opportunities to work on robotic space missions and planetary science projects.

Highest Impact

Despite its small size, Caltech consistently ranks #1 in the world for the impact of its research (citations per faculty member).

Honor Code

"No member of the Caltech community shall take unfair advantage of any other member." This allows for take-home exams and high trust.

House System

Similar to Harry Potter, undergraduates live in 8 houses, each with unique traditions, dining, and social cultures that last a lifetime.

Scholarships & Financial Aid

Need-Blind (Domestic)

Caltech is need-blind for US citizens and permanent residents. Admission decisions are made without looking at financial status.

100% Need Met

Caltech guarantees to meet 100% of the demonstrated financial need for all admitted students (including international students).

International Aid

Financial aid is available for international students, but admission is "need-aware" (very competitive for those asking for aid).

No Merit Aid

Caltech does not offer scholarships based on academic merit or athletics. All aid is strictly based on financial need.

Graduate Fellowships

~99% of doctoral students receive full financial support, including tuition remission and a stipend for living expenses.

Work-Study

Opportunities to work in labs, libraries, or dining services to help cover personal expenses.

Innovation & Facilities

Observatories

Caltech operates the Palomar Observatory and the W.M. Keck Observatory in Hawaii, giving students access to world-class astronomy tools.

JPL (NASA)

The Jet Propulsion Laboratory is a federally funded R&D center managed by Caltech, located just a few miles from campus.

Seismological Lab

The Caltech Seismo Lab is a global leader in earthquake science and geophysics research.

Beckman Institute

A center for interdisciplinary research in the chemical and biological sciences, fostering collaboration across fields.

Turtle Pond

The "Gene Pool" and the Turtle Pond are serene spots on campus (and the site of many student traditions and pranks).

Red Door Marketplace

The central social hub for coffee and collaboration, where students and Nobel laureates often bump into each other.

Research First

SURF Program

Summer Undergraduate Research Fellowships (SURF) allow students to conduct independent research under faculty mentors. Over 50% of students participate.

Quantum Computing

A hub for AWS Center for Quantum Computing and heavy research into quantum information and matter.

Sustainability

The Resnick Sustainability Institute fosters research into energy generation, storage, and conversion.

Bioengineering

Pioneering work in synthetic biology, neural engineering, and medical diagnostics.

Tectonics

The Tectonics Observatory researches the geological evolution of the Earth and other planets.

Entry Requirements

Undergraduate Requirements

  • STEM Passion: Must demonstrate intense curiosity and high aptitude for math and science.
  • Academic Preparation: Calculus and Physics are absolute prerequisites.
  • Standardized Tests: REQUIRED. Caltech reinstated the SAT/ACT requirement in 2024.
  • English Proficiency: TOEFL (recommended 100+) or IELTS (7.0+) for non-native speakers.
  • Essays: Short responses focusing on your love for STEM, collaboration, and fun.
  • Teacher Evals: One from a math/science teacher, one from humanities/social science.
  • Research Portfolio: Highly recommended to submit research papers or maker portfolios if you have them.

Graduate Requirements

  • Bachelor's Degree: Must be from a rigorous program with a very high GPA (3.8-4.0 range typical).
  • Research Experience: Crucial. You must have significant prior research experience and publications.
  • Letters of Recommendation: 3 strong letters from faculty who can attest to your research potential.
  • Statement of Purpose: A focused essay detailing your research interests and fit with specific faculty.
  • English Proficiency: TOEFL is strictly required for international applicants (IELTS often not accepted).
  • GRE: Requirements vary by department (Physics usually requires Subject GRE). Check specific program.
  • CV/Resume: Highlighting technical skills, papers, and conference presentations.

Frequently Asked Questions

Is Caltech harder than MIT?
Both are incredibly rigorous. Caltech is smaller (1,000 undergrads vs MIT's 4,500) and arguably has a more intense focus on theoretical science and a strict Core Curriculum that every student must pass.
What is the Core Curriculum?
Every Caltech undergrad, regardless of major, must take: 5 terms of math, 5 terms of physics, 2 terms of chemistry, 1 term of biology, plus humanities and social sciences. It ensures a deep scientific foundation.
What is the acceptance rate?
Caltech is extremely selective, with an acceptance rate typically around 2-3%. They look specifically for students who demonstrate exceptional aptitude in STEM.
Is it true that grades are Pass/Fail?
Only for the first two terms (Freshman year). This "shadow grading" period allows students to adjust to the intense workload and collaborate without worrying about GPA immediately.

Ready for the Challenge?

Admission to Caltech requires more than just good grades. It requires a demonstrated passion for scientific discovery. Let us help you prove it.
