High School Rankings
San Mateo County · 2025 · ≥50 seniors
What is UC Reach? UC Reach = top-6 UC admits ÷ senior class size,
summing each campus — measured against a school's
entire graduating class, across 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.
This board needs a class of 100+ seniors. Schools smaller than that are ranked on the small-schools board below — which is where California's highest UC Reach Score actually sits.
Ranked separately because they graduate 25–99 seniors — magnet programs, specialized charters and small privates. A class of 60 swings far more year to year than a class of 600, so mixing them into the boards above would compare unlike things. The state's single highest UC Reach Score sits on this board, not the one above it.

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.

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.

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. Campus admits are SUMMED — UC publishes no
per-school unique-student count, so a senior admitted to more than one of the 6 campuses is counted at each,
and 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.
