Getting into California Institute of Technology

California Institute of Technology admits 2.6% of applicants. In the federal admissions survey it reports that SAT and ACT scores are neither required nor recommended.

About 1 in 39 applicants are admitted, at a college of 987 undergraduates.

US Department of Education, College Scorecard (2026-09-17). Percentiles describe students who enrolled, not everyone admitted.

Does California Institute of Technology require the SAT or ACT?
Not according to the federal admissions survey, where California Institute of Technology reports that SAT and ACT scores are neither required nor recommended. Read that as "not required" rather than "never looked at": the survey lags real policy by a cycle or more, and some colleges carrying this flag have since brought testing back while others genuinely ignore scores altogether. Check California Institute of Technology's own admissions page before deciding whether to sit or send a test, and treat that page as the answer where the two disagree. Either way, grades and course load are doing most of the work here.
What GPA do you need for California Institute of Technology?
The honest answer is that the federal data behind this page does not contain one. Colleges report their admit rate and their enrolled students' test scores to the Department of Education; they do not report a GPA distribution, so any site quoting an exact average GPA for California Institute of Technology is either reading that college's own Common Data Set or estimating. What the reported data does say is that California Institute of Technology admits 2.6% of applicants, and the more selective a college is, the closer to the top of the class its admitted students sit and the more the strength of your course load counts alongside the number itself.
How hard is it to get into California Institute of Technology?
California Institute of Technology admits 2.6% of the people who apply, which is about 1 in 39 applicants. At that rate no set of numbers makes admission likely, a perfect one included, because the college turns away far more qualified applicants than it takes. Strong grades and scores get the application read; the essays, the recommendations and what you have actually done decide it from there.
