🏆 Top 10 in San Joaquin County — UC Reach

San Joaquin 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.

🎯 Specialized high schools — San Joaquin 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

25 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.
