Caltech students come from all over the world, bringing diverse experiences, perspectives, and passions. They share an unbridled sense of curiosity and an extraordinary aptitude for science, engineering, and math that are nurtured in one of the world's most rigorous academic environments.

A wide array of learning opportunities, hands-on research, and collaborations with faculty empower Caltech students to generate world-changing ideas and innovations.

Undergraduate Admissions

Each year, we welcome about 235 new first-year students to the Caltech community, plus a handful of transfer and 3/2 students. With an undergraduate body of just under 1,000, each student plays an active role in our small community of creative problem solvers through their vast STEM potential, unique background, and drive to solve society’s most pressing challenges.

Graduate Admissions

Caltech annually enrolls graduate students across 30 different academic programs, which span the natural, physical, and applied sciences, as well as engineering disciplines. Graduate work and research at Caltech, however, is inherently interdisciplinary so the 1,200 students pursuing a MS, PhD, or Engineer's degree often work across academic divisions and departments.
