Frequently asked questions

Does California Institute of Technology require the SAT or ACT?

California Institute of Technology requires SAT or ACT scores for the 2026-27 cycle. Caltech reinstated required SAT/ACT testing in 2024 (effective for the Class of 2029 cycle) and it remains required for 2026-27 (Class of 2031). Caltech uses a 'bucket' system that masks exact scores above certain thresholds (Bucket A: SAT 780-800/ACT 35-36; Bucket B: SAT 750-770/ACT 33-34 — exact number hidden); only scores below SAT 750/ACT 33 are shown exactly to reviewers. No minimum score and no preferred test.

Score ranges: College Scorecard API — U.S. Department of Education (api.data.gov) and Editorial overrides layer (overrides.json) — Common Data Set & institutional sources. They describe students who enrolled, not everyone admitted. Test policy: California Institute of Technology admissions, verified for 2026-27.
