Data sources and methodology
Open Admit is an independent public-data project by Assertion Labs. It covers 3,816 degree-granting undergraduate institutions active in fall 2023, not every U.S. educational institution.
Reporting periods and provenance
Directory: HD2023. Admissions and test scores: ADM2023. Undergraduate enrollment: EF2023A, EFALEVEL=2. Open-admission policy: IC2023. The snapshot was retrieved 2026-11-08. These historical records are not current-cycle advice or a live campus list.
Three manually checked Common Data Set supplements have their own 2024–25 years and school source links. Annual nationwide CDS collection is not yet automated.

Calculations and missing values
Admission rate = admitted ÷ applicants from the same cohort, only where counts are usable and applicants exceed zero. Medians are unweighted school medians and exclude unavailable values. A missing value never becomes zero. Original NCES correction and imputation flags remain in the downloadable dataset.
SAT/ACT ranges describe the middle 50% of enrolled students whose scores were used in admission. Separate SAT section percentiles cannot be summed. Peer benchmarks match institutional type and degree level, not quality.
IPEDS allocates unknown/another-gender enrollment into men/women totals; supplementary gender counts overlap and must not be added to those totals. Regular-decision rates are not inferred from different source cohorts.
