🏆 Top 10 in Marin County — UC Reach Score

Marin County · 2025 · ≥50 seniors
What is UC Reach? UC Reach = unique top-6 UC admits ÷ senior class size — the share of a school's entire graduating class that reaches the six most selective UCs (Berkeley, UCLA, San Diego, Santa Barbara, Irvine, Davis). It's a better gauge of school-wide success than admit rate, which only reflects the handful of students who applied.
Why it beats admit rate: if 6 students apply to the top UCs and all get in, that's a 100% admit rate — but at a 1,000-senior school it's a UC Reach Score of just 0.6 (6 ÷ 1,000). By contrast, a school where 250 of 1,000 seniors land a top-UC admit has a UC Reach Score of 25 — far stronger, even though its admit rate is lower.
Why some schools are over 100? Out of every 100 seniors at these schools, the class is generating more than 100 admissions to the six most selective UCs — meaning the typical strong student is getting in at multiple top campuses (UCLA + UCSD, or Berkeley + UCSB + Irvine, for example). It's a rare achievement: fewer than 1% of California high schools clear a UC Reach Score of 100.

🎯 Specialized high schools — Marin County · 2025

Top UC Reach for schools with senior classes of 25–99. These are typically magnet programs, specialized charters, and small Catholic preps — too small to compare cleanly against comprehensive public high schools, but the most UC-effective small schools in California are here.

Demand momentum — biggest gaps vs the county baseline

grade-12 enrollment Δ vs. county · ≥80 students

The demographic tide is shrinking CA enrollment ~10% over 7 years statewide, so absolute decline alone is noise. The gap vs the county baseline is the actionable signal — schools losing share faster than their demographic floor are the ones to watch. Reflects the current county/type filter.

GPA Performance — over/under their predicted UC admit rate

7 schools eligible · 2025

Each dot is one school. The diagonal is the per-campus GPA expectation — points above it admit students at higher rates than their GPA mix predicts; points below admit at lower rates. Schools need ≥30 top-6 UC applications and data across ≥3 campuses to appear.

UC Reach = top-6 UC admits ÷ senior class size. Where UCOP has not published unique-student totals, campus admits are summed — students admitted to more than one of the 6 campuses are counted at each, so values above 100 indicate strong students winning multiple competitive UC offers. Schools with fewer than 100 seniors are excluded from the leaderboard by default — a small cohort with one strong year can otherwise dominate. See methodology →
