High School Rankings
Sonoma 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 and bottom schools by UC Reach, split public/charter vs private (≥50 seniors).

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 measures who gets in. These lenses measure the upstream pipeline (A-G), the downstream outcome (UC graduation), the capacity that drives the pipeline (counselors), reliability over time (consistency), grade-11 academic preparation (CAASPP SBAC ELA & Math), and private-school financial strength.

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.

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.
