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.
