About the university

The California Institute of Technology was founded in 1891. Over its more than 130 years of existence, it has become a symbol of scientific concentration: with a campus population smaller than most high schools, Caltech operates NASA’s Jet Propulsion Laboratory (JPL) and is responsible for the Mars Rover, Voyager missions, and the maintenance of the Hubble Telescope.

Caltech’s main distinguishing feature is its 3:1 faculty-to-student ratio, one of the best in the United States. This means that every student has real access to leading scientists, including Nobel laureates. The institute has 46 Nobel laureates associated with it – including physicist Richard Feynman and two-time laureate Linus Pauling.

Famous alumni include Intel co-founder Gordon Moore. The campus is located in Pasadena, among palm trees against the backdrop of the San Gabriel Mountains, about 18 kilometers from downtown Los Angeles – small but rich in research infrastructure.

Faculties

Caltech offers programs exclusively in the fields of science and engineering, which is a fundamental difference from most universities. The main areas of study are divided into six academic departments:

  • Physics, Mathematics, and Astronomy is one of the historically strongest departments, focusing on fundamental research.
  • Engineering and Applied Sciences includes aerospace, mechanical, and electrical engineering, as well as computer science and computational engineering.
  • Chemistry and Chemical Engineering offer powerful laboratory facilities and connections to the pharmaceutical and industrial sectors.
  • Biology and Bioengineering – research at the intersection of molecular biology, neuroscience, and biomedical engineering.
  • Geological and Planetary Sciences – a unique field associated with JPL and NASA’s planetary missions.
  • Humanities and Social Sciences – a required component of the program for all students, but not a standalone field of study.

Approximately 80-90% of undergraduate students participate in real research, often starting from their first year through the SURF (Summer Undergraduate Research Fellowships) program. At the Master’s and doctoral levels, training is organized through the same six departments, with almost 50 separate graduate programs (graduate options).

Arrangement

Campus

The Caltech campus occupies 124 acres in downtown Pasadena, within walking distance of the historic Old Town Pasadena. Housing is guaranteed to all first-year undergraduate andmaster’s/doctoral students in their first year.

Instead of traditional dormitories with hundreds of students, Caltech has a house system of eight student houses (house system) — each with its own self-governing and traditions. This forms a dense and informal academic community, where students of different courses and fields interact closely with each other.

Catalina Apartments are available on campus for graduate and postdoctoral students, with new grad students having priority for housing. The campus is home to about 50 research institutes and centers, including the Resnick Sustainability Institute and the Tectonics Observatory, as well as the central Athenaeum building, a venue for formal dining, meetings, and campus events.

Student clubs

Despite the compact size of the campus, Caltech offers a vibrant student life with over 100 student clubs ranging from robotics to music, 13 varsity sports under the Caltech Beavers brand, and its own tradition of Ditch Day, where upperclassmen leave the campus and younger students solve the engineering challenges they left behind.

Admission process

Admission to the California Institute of Technology is one of the most competitive processes among technical universities in the world. The acceptance rate is about 3.78% for the class of 2029, which is lower than in most Ivy League universities.

An important feature is that Caltech accepts applications through the Common Application, but evaluates them using its own logic, which is different from most universities. The institute looks not just at academic achievements, but also at genuine scientific interest, research motivation, and the ability to work in an intense intellectual environment.

Selecting a program.

Caltech offers exclusively STEM-related courses. Students enroll in the institute as a whole and choose their major after admission.

Academic documents.

The Institute expects exceptional results in mathematics and the sciences. Strong grades in core subjects are required: at least four years of mathematics (including algebra and beyond), one year of chemistry, one year of physics, and at least three years of English.

Essay.

Caltech asks its own additional questions, which are aimed at revealing scientific thinking, specific projects, and personal motivation. Standard answers do not work; the institute expects specifics. Historically, about a third of the applicants submit a portfolio or technical work (“maker work”).

Letters of recommendation.

Two letters from science teachers and one from a school counselor. The letters should confirm analytical abilities rather than simply listing achievements.

Confirmation of English level.

International students must pass the TOEFL, IELTS, or Duolingo English Test if English is not their native language or the language of instruction at their school.

Submission deadlines.

The Restrictive Early Action tour is until November 1, and the main tour (Regular Decision) is until January 3. Caltech explicitly states that the acceptance rate is the same for both rounds (below 5%), and warns applicants in advance not to apply early solely for the sake of improving their chances.

Admission Features

Educational process

For international applicants, Caltech applies a need-aware policy for admission, which means that the family’s financial situation may influence the decision to enroll, since the amount of funds available to help international students is limited. At the same time, the institute covers 100% of the confirmed financial need for all accepted students who have applied for assistance.

Since admission to the class of 2029, Caltech has returned the mandatory SAT or ACT exam — the institute found that 95% of applicants still sent points even during the test-optional policy period. The average range of scores for admitted students is 1540–1590 on the SAT and 35–36 on the ACT.

What enhances the application of a foreign applicant:

  • Victories or prizes in international competitions in mathematics, physics, computer science or chemistry.
  • Real research experience – participation in scientific projects, laboratory work, publications.
  • Specific technical achievements: own developments, participation in scientific competitions.
  • High results in specialized subjects and standardized tests.

Scholarships and grants

All financial aid at Caltech is targeted and based on need. The institute does not offer scholarships based on academic merit. For students from the United States, admission is need-blind, and family income does not affect the admission decision. However, for families with confirmed financial need, Caltech covers 100% of expenses.

Key conditions:

  • Families with incomes up to $100,000 per year (with typical assets) typically receive a loan-free aid package that covers tuition, room, and board in full.
  • Families with incomes up to $200,000 can expect aid that covers at least tuition.
  • For international students, the institute applies a need-aware admission policy, but fully covers the need of all admitted students who apply for aid.
  • Outside scholarships (external scholarships from organizations and foundations) usually reduce the amount of Caltech’s institutional aid, but they still lower the total cost of tuition for the student.
  • Doctoral students receive a separate funding package: the scholarship will increase to $50,000 per year (approximately $4,020 per month) starting from September 1, 2026. In addition to the scholarship, doctoral students receive full tuition waivers and 90% subsidized health insurance.

Prospects after graduation

The main career advantage for Caltech graduates is their proximity to the NASA Jet Propulsion Laboratory (JPL), which the institute manages directly. Students have the opportunity to complete internships at JPL, as well as at companies such as SpaceX, Boeing, Google DeepMind, and national research laboratories.

The six-year median salary for Caltech graduates is around $132,140, one of the highest among US universities. The average starting salary for graduates in engineering and computer science is between $140,000 and $175,000 per year.

Caltech’s four-year graduation rate is 77%, which is lower than most top universities, but this is a direct result of the program’s extremely high academic workload and not a sign of future employment challenges.

Scientific achievements

Caltech manages NASA’s Jet Propulsion Laboratory (JPL), the center responsible for robotic exploration of the solar system, including the Mars Rover, Voyager missions, and the servicing of the Hubble Space Telescope. This is a unique partnership that no other university in the world has.

The institute has 46 Nobel laureates among its faculty and alumni, including physicist Richard Feynman and two-time laureate Linus Pauling (Nobel Prize in Chemistry and Nobel Peace Prize). In terms of the number of Nobel laureates per capita of students and staff, Caltech remains one of the leaders among universities in the world.

The campus is home to about 50 research institutes and centers, including the Resnick Sustainability Institute (sustainable energy) and the Tectonics Observatory (geology and plate tectonics). Caltech also operates its own seismological laboratory and a network of international observatories.
