Top 10% UC Reach in California 📖25 AP courses 📝SAT 1430 avg 🏅12 National Merit Semifinalists

🧭 A parent's read

  • The UC pipeline here is real. 71 admissions to the top six UC campuses for a class of 111 seniors puts this school in roughly the top 5% of California high schools.
  • 12 National Merit Semifinalists in one class. That's roughly 1 in 9 seniors reaching the top ~1% of the PSAT nationally — a density few schools anywhere can match.
  • Elite admits are rare — here and everywhere. Berkeley and UCLA admitted 20 of this class's 284 UC applications. The strong middle campuses — San Diego, Santa Barbara, Irvine, Davis — are where most real UC outcomes happen.
  • One question for any counselor: who should still test? Plenty of strong students skip the SAT/ACT now — but merit scholarships at dozens of colleges still key off scores. Ask how the school decides who should still sit for one.

No SBAC data for private schools — and that's not the metric you want anyway

California's Smarter Balanced (CAASPP) assessment is administered by the state, by statute, to public & charter schools only. Private schools don't sit for it. That's why the SBAC card is missing on this profile — not a data gap on our side, a deliberate scope of the state's testing program.

For private schools, UC Reach is the stronger academic signal anyway. SBAC measures grade-11 inputs (proficiency on a state standard); UC Reach measures outputs (who actually got into the most selective UCs). For private-school families weighing tuition against college outcomes, the outputs are the relevant signal.

How we infer the tier labels: Each tier comes from the statewide CA admit rate at that GPA band at that UC. The "vs peers" column compares this school's lift (admit GPA − applicant GPA) to the average lift at ~100–300 other CA schools with similar applicant pool GPA. What this isn't: a guarantee. UC comprehensive review weighs essays, course rigor, demographics, and context-of-opportunity beyond GPA. A 3.9 with strong context can land an admit; a 4.0 with weak essays can be denied. Use as a baseline expectation, not a verdict. Per-campus year is shown when it differs from the headline year (UCOP doesn't always publish admit-GPA for every campus every year).

What This Means

A large share of the senior class applies to UC, indicating strong college-going culture and UC pipeline development.
A large share of the class applies to UC, so the admit rate runs lower than the application volume alone might suggest — expected when many students apply broadly, including to reach campuses. UC Reach (which credits every admit relative to the class) is the truer read of how the class fares: a strong Reach alongside a moderate admit rate is healthy, not a contradiction.
UC Reach is very strong — more than 64% of seniors are earning UC admission. This places the school among California's highest-performing high schools on this metric.
Strong UC Reach paired with very low yield: this school's students are earning UC admission at high rates and then enrolling elsewhere — almost certainly at the most selective private universities (Ivies, Stanford, MIT, the top liberal-arts colleges) or elite out-of-state flagships. UC is functioning as a credentialing-grade backup rather than a destination.
The school generates broad UC access, but fewer students are reaching the most selective UC campuses (UCLA, Berkeley, UCSD, UCSB, UCI). Targeted academic enrichment and campus-fit advising may help.
Berkeley and UCLA admit volume is strong — a clear high-end signal for this school's academic preparation.
UC Reach has declined meaningfully year-over-year. This should be reviewed in context of applicant volume, GPA trends, course rigor changes, and peer-school performance before drawing conclusions.
Note: the UC Reach Score sums campus-level admits across the top-six UC campuses, so a student admitted to both UCLA and UCSD is counted at each. It reflects competitive admit volume relative to class size — admit-events, not distinct students — which is why a Score can exceed 100.
