Caltech operates on a quarter system with three main intakes: Fall, Winter, and Spring. The Fall term is the primary admission period for most programs, particularly undergraduate studies. Graduate programs may offer more flexibility with multiple entry points.
Undergraduate applications are due by November 1 (Early Action) and January 3 (Regular Decision). Graduate deadlines vary by department but typically fall between December and January for Fall admission. Some programs may accept applications for Winter or Spring, though these are less common.
Prospective students should verify specific deadlines on Caltech’s official website or department pages, as dates may shift slightly annually.
