• ▸Harbor High School's UC Reach Score has declined meaningfully from a peak of 39 in 2022 to 28 in 2025 — a 11-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.

• ▸Across the top-6 UC campuses, Harbor High School is admitting at roughly +10 percentage points above what its average applicant GPA (4.06) alone would predict (34% 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 up 2% (230→234 from 2018 to 2026), outpacing the peer-group median of -5%.
• ▸Enrollment has been growing (+0.9%/yr); projects to ~1021 by 2029.
