View latest 990 PDF → Tuition-per-student is total program-service revenue divided by latest enrollment — a rough average that includes auxiliary revenue (athletics, food service, etc.); the actual published tuition can differ. Form 990 is filed annually under penalty of perjury, so the financial scale figures are authoritative.

Enrollment Reach vs. Yield: Reach answers "of the whole senior class, what % ended up at UC?" — denominator is everyone. High Yield with low Enrollment Reach is common at elite privates: most admits matriculate, but the school sends most of its class to non-UC selective colleges.

⚠ Campus-level totals may count one student admitted to multiple UC campuses more than once. Admit Volume metrics are not the same as UC Reach, which requires unique-student counts. See methodology →

What This Means

A relatively small share of the senior class is entering the UC application pipeline. This may signal limited A-G completion, UC awareness gaps, or counseling capacity constraints. Broadening access is the highest-leverage opportunity for this school.
Note: admit counts used here are campus-level totals. A student admitted to both UCLA and UCSD is counted twice. When UCOP unique-student data becomes available it will be loaded automatically and the labels will update.
