📊 What this number means

112.8% 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 40.5% — this still clears the county top-10% bar (68.1%).

Against similar schools, Quarry Lane School stands out clearly — the peer-group median is 61.2%.

This places Quarry Lane School in the elite tier statewide — the top-1% threshold is 97.3%.

Overall, Quarry Lane School's UC Reach is higher than 99% of California high schools (978 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 100% UC Reach.

UC Application Reach ⓘ

561.5%

438 applications

Exceptionally ambitious student body. The typical senior is applying to about 6 of the 6 most selective UCs — a culture of pursuing every major UC option.

In context: CA median 74.9% · Top 10% statewide ≥ 241.0% · Alameda Co. Top 10% ≥ 361.9% · higher than 99% of CA HS.

UC Admit Rate ⓘ

In context: CA median 26.1% · Top 10% statewide ≥ 40.5% · higher than 17% of CA HS.

UC Yield Rate ⓘ

10.2%

9 enrolled of 88 admitted

Yield vs. Enrollment Reach: Yield answers "of UC admits, what % chose UC?" — denominator is just the admits. A small admitted cohort can post a low yield even when the school sends a healthy share of its class to UC.

UC Enrollment Reach ⓘ

11.5%

9 enrollees / 78 seniors

Enrollment Reach vs. Yield: Reach answers "of the whole senior class, what % ended up at UC?" — denominator is everyone. High Yield with low Enrollment Reach is common at elite privates: most admits matriculate, but the school sends most of its class to non-UC selective colleges.

UC funnel — which kids are getting in at what GPA

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).

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.

Quarry Lane School — Enrollment & Outcomes Snapshot

Private · secular · Dublin · vs. 10 most similar nearby schools

▸On UC Reach, Quarry Lane School sits near the top of its similar-school group (ranked #2 of 11): 113% vs. a peer median of 61%.
▸Quarry Lane School's UC Reach has declined meaningfully from a peak of 158% in 2024 to 113% in 2025 — a 46-point drop that warrants attention. Multi-year UC Reach declines of this size often signal something specific (leadership change, comp-program shift, demographic move) rather than year-to-year noise. This is the kind of trajectory an Enrollment Trend Audit unpacks.
▸Across the top-6 UC campuses, Quarry Lane School is admitting at roughly +6 percentage points above what its average applicant GPA (4.065) alone would predict (29% actual vs. 22% expected). That's a meaningful signal — it can reflect UC's track record with this school's graduates, students presenting strongly in UC's holistic review (essays, EC's, context), or institutional familiarity helping at the margin. The data can't distinguish which, but the pattern itself is real and worth understanding.
▸Senior-class enrollment is up 34% (58→78 from 2020 to 2025), outpacing the peer-group median of +6%.
▸Enrollment has been growing (+11.0%/yr); projects to ~1416 by 2028.

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: admit counts used here are campus-level totals. A student admitted to both UCLA and UCSD is counted twice. When UCOP unique-student data becomes available it will be loaded automatically and the labels will update.
