Warren High School

• ▸On UC Reach Score, Warren High School sits in the middle of its similar-school group (ranked #5 of 11): 17 vs. a peer median of 16.
• ▸Warren High School's UC Reach Score has declined meaningfully from a peak of 27 in 2021 to 17 in 2025 — a 10-point drop that warrants attention. Multi-year UC Reach declines of this size often signal something specific (leadership change, comp-program shift, demographic move) rather than year-to-year noise. This is the kind of trajectory an Enrollment Trend Audit unpacks.
• ▸Senior-class enrollment is down 2% (924→902 from 2018 to 2026), outpacing the peer-group median of -14%.
• ▸In business terms, this is market-share growth during a market contraction. Los Angeles County's senior population shrank 5% over the same window — Warren High School only shrank 2%. So Warren High School picked up about 3 percentage points of relative share — families chose it over the alternatives even as the overall pool got smaller. That's overperforming the market in a shrinking market.
• ▸At its recent rate (-0.1%/yr), enrollment projects to ~3571 by 2029 — about 13 fewer students than today.
