🏆 Top 10 in Marin County — UC Reach

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 of just 0.6% (6 ÷ 1,000). By contrast, a school where 250 of 1,000 seniors land a top-UC admit has a 25% UC Reach — 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 100% UC Reach.

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.

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 →
