- ▸On UC Reach, Gretchen Whitney High School sits near the top of its similar-school group (ranked #1 of 10): 126% vs. a peer median of 16%.
- ▸Gretchen Whitney High School's UC Reach has declined meaningfully from a peak of 141% in 2021 to 126% in 2025 — a 15-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.
- ▸Across the top-6 UC campuses, Gretchen Whitney High School is admitting at roughly +5 percentage points above what its average applicant GPA (4.159) alone would predict (30% actual vs. 25% 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 up 4% (164→170 from 2018 to 2026), outpacing the peer-group median of -20%.
