⭐Elite UC Reach — Top 1% in CA 🏅5 National Merit Semifinalists

🧭 A parent's read

  • The UC pipeline here is real. 88 admissions to the top six UC campuses for a class of 78 seniors puts this school in the top handful of schools in California.
  • 5 National Merit Semifinalists in one class. That's roughly 1 in 16 seniors reaching the top ~1% of the PSAT nationally — a density few schools anywhere can match.
  • A deeply UC-focused culture. Seniors here file about 5.6 UC applications each — among the most UC-oriented schools in California. The counseling office lives and breathes this system.
  • Elite admits are rare — here and everywhere. Berkeley and UCLA admitted 12 of this class's 438 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.

📊 What this number means

113 is exceptional and very rare. For every 100 seniors at Quarry Lane School, the school is generating roughly 113 admissions to California's six most selective UCs (UCB, UCLA, UCSD, UCSB, UCI, UCD). The typical strong senior here is winning admission at multiple top campuses — a result fewer than 1% of California high schools achieve.

In Alameda County — a competitive market where the median is already 40 — this still clears the county top-10% bar (68).

Against similar schools, Quarry Lane School stands out clearly — the peer-group median is 61.

This places Quarry Lane School in the elite tier statewide — the top-1% threshold is 97.

Overall, Quarry Lane School's UC Reach is higher than 99% of California high schools (980 ranked).

Why is this over 100? Out of every 100 seniors at this school, the class is generating more than 100 admissions to California's six most selective UCs. The typical strong senior here is being admitted at multiple top-6 campuses — UCLA + UCSD, or Berkeley + UCSB + UC Irvine, for example. It's a rare achievement; fewer than 1% of California high schools clear a UC Reach Score of 100.

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 113% 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.
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.
