California High School Enrollment Trends

Senior class size (grade 12) across California, 2018–2025. The denominator behind every Reach metric.

Source: California Department of Education Census Day Enrollment (public + charter) and Private School Affidavit. A shrinking senior cohort can push Reach percentages up at the school level even when admit counts hold flat — context that matters when reading year-over-year changes.

Grade-12 enrollment by school type

Statewide totals — sum of grade-12 enrollment across all schools with data for each year. Charter schools are grouped with public because charter enrollment data in the CDE feed maps to one row in this database.

Statewide Grade 12 — 2025

490,325

+3.0% since 2020

Public + Charter

463,049

+1.8% since 2018 · 2176 schools

Private

27,276

+1.7% since 2020 · 327 schools

Note on baselines: Private % computed since 2020 — CDE's private enrollment file broadened that year (from 8 schools reporting in 2018 to 335 in 2020); using 2018 would compare unlike datasets.

Leaders & laggards by enrollment trend

Top 25 schools growing fastest, bottom 25 shrinking fastest, among comprehensive UC-feeding high schools. Compares earliest vs latest year on file. Excludes schools with fewer than 30 baseline seniors and those with little or no UC application history (continuation, independent-study, and credit-recovery programs) — their grade-12 counts swing wildly and aren't comparable. The shrinking list also requires at least 100 total students.
