When Is the Caltech Application Deadline?

First-year applicants can apply to Caltech through two different routes with their own deadlines:

The dates above apply only to first-year applicants. Dates for transfer and financial aid applicants will be covered later in this blog.

Caltech Restrictive Early Action deadline

Caltech’s REA deadline is November 1, but you have until November 6 to submit required and supplemental materials, and until November 30 to complete standardized testing. Results come out in mid-December.

REA is non-binding, so those who are accepted in this round still have until May 1 to make their decision. Deferred applications will get a second review in the RD pool.

Caltech Regular Decision deadline

Caltech’s RD deadline is January 4. Applicants have until January 10 to submit other required and supplemental materials, and until December 31, 2026 to complete standardized testing. Results are released in mid-March. Accepted students have until May 1 to reply.

If you’re applying through Caltech’s RD route, you can also apply to as many other colleges as you want and keep your college options open so you can compare offers when all decisions are released.

Caltech Transfer Application Deadline

Caltech’s transfer application deadline is February 1, 2027. Applicants will also be required to take a physics and math exam since Caltech wants to test them on their mastery of material covered in Caltech’s first year Core Curriculum. These exams are due on February 15.

Transfer decisions are released in mid-April, and accepted students must reply by June 1.

Caltech Financial Aid Application Deadline

The Caltech financial aid deadline you should meet depends on the application round you are in:

Caltech says that submitting your application after the priority deadlines doesn’t mean you’ll receive less aid, but it will take longer for you to receive your decision. However, missing the hard deadlines means you won’t receive any aid.

Frequently Asked Questions

1. What if I miss the Caltech application deadline?

3. Can I request a Caltech application deadline extension?

No, Caltech doesn’t grant application deadline extensions. If you’re worried about hitting the deadline, aim to submit your application at least a day before in case you run into technical difficulties.
