It's no secret that admission to Caltech is selective; we welcome only about 230 new freshmen and 10 to 15 new transfer students to campus each fall. These students come to Caltech from all over the United States—and the world—bringing with them diverse experiences, perspectives, and passions.

Hoping to be among next year's undergraduate class? All we ask is that you share the typical Caltech student's unbridled sense of curiosity and extraordinary aptitude for and interest in science, engineering, and technology.

If you are interested in applying for admission as a graduate student, please visit our graduate admissions website.
