All students will be given our full consideration through Caltech's holistic review method. The following standardized test are required for a complete freshman application. We do not accept any substitutes for these tests.
- SAT or ACT
- Note: As of July 2018, Caltech no longer requires the SAT Essay or ACT Writing exam sections. Additionally, these sections will not be considered in the application review process.
- SAT Subject Test in Mathematics Level 2
- 1 SAT science subject test: biology (ecological), biology (molecular), chemistry, or physics
How to Submit Your Test Score Information
ALL required tests must be completed prior to the application deadline. If you are applying to meet our Early Action (November 1) deadline, then you may submit October test scores. If you are applying to meet our Regular Decision (January 3) deadline, then you may submit December test scores. If you are taking an exam shortly before your application deadline, we recommend that you add Caltech to the list of schools that will receive your score report as soon as it becomes available.
We will accept self-reported test score information directly from students submitted either through the application or through your Caltech Student Portal. We do not require official test score reports from applicants. We will request official test score information from students who are offered admission.
The Admissions Committee reserves the right to withdraw the applications of students who do not submit all of our required testing.
We strongly recommend that you report all of your available standardized test scores because the Admissions Committee will be certain to review the strongest score in each category, across all of the exam(s) you've taken. Caltech will superscore across SAT exam dates and across the same test version. Thus, if you took both the "old" and the "new" SAT, we will not superscore across those two different versions.
The ACT does not condone superscoring, so Caltech will not calculate a new composite ACT score; however, if you took the ACT multiple times, the Admissions Committee will take note of the differences in your score performances across sections.
