- ▸On UC Reach, Castle Park High School sits in the middle of its similar-school group (ranked #6 of 9): 17% vs. a peer median of 20%.
- ▸Its UC Reach has risen 8 points since 2018.
- ▸Across the top-6 UC campuses, Castle Park High School is admitting at roughly +16 percentage points above what its average applicant GPA (3.932) alone would predict (39% actual vs. 23% expected). That's a meaningful signal — it can reflect UC's track record with this school's graduates, students presenting strongly in UC's holistic review (essays, EC's, context), or institutional familiarity helping at the margin. The data can't distinguish which, but the pattern itself is real and worth understanding.
- ▸Senior-class enrollment is down 2% (352→345 from 2018 to 2026), outpacing the peer-group median of -19%.
- ▸In business terms, this is market-share growth during a market contraction. San Diego County's senior population shrank 8% over the same window — Castle Park High School only shrank 2%. So Castle Park High School picked up about 6 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 (-2.9%/yr), enrollment projects to ~1206 by 2029 — about 112 fewer students than today.
