California Institute of Technology

University, Graduate school in Pasadena, The United States

The California Institute of Technology (Caltech) is a science and engineering university in Pasadena, California. Its teaching and research are organised in six divisions: Biology and Biological Engineering; Chemistry and Chemical Engineering; Engineering and Applied Science; Geological and Planetary Sciences; Humanities and Social Sciences; and Physics, Mathematics and Astronomy. Its research facilities include the IPAC astronomy center, and students also do research at NASA's Jet Propulsion Laboratory (JPL).

The undergraduate body is just under 1,000 students, with about 235 new first-year students each year plus a small number of transfer and 3/2 students, and the student-faculty ratio is 3:1. Graduate students enrol in 30 programmes across the natural, physical and applied sciences and engineering, leading to MS, PhD or Engineer's degrees. According to the institute, 90% of undergraduates take part in research, on campus, abroad, at JPL or at an observatory, and students can study abroad in cities such as Cambridge, London, Copenhagen, Edinburgh, Paris and Melbourne.

An International Office supports students from abroad. Caltech meets 100% of admitted students' demonstrated financial need but awards no merit scholarships; admission is need-aware for international students because aid funds for them are limited.

Graduate programmes

Caltech enrols graduate students in 30 academic programmes across the natural, physical and applied sciences and engineering, leading to MS, PhD or Engineer's degrees. Graduate research is interdisciplinary, and students often work across divisions and departments. Doctoral students' tuition is fully covered by merit-based financial support.

Scholarships and financial aid

Undergraduate financial aid at Caltech is need-based only; the institute awards no merit scholarships. It meets 100% of admitted students' demonstrated need with a mix of scholarships and grants, work-study and loans. Admission is need-blind for domestic students but need-aware for international students, because aid funds for them are limited. For the class entering in fall 2026, average grant aid was just under US$69,000. Doctoral students' tuition is fully covered by merit-based support.
