🧭 A parent's read

  • The UC pipeline here is real. 322 admissions to the top six UC campuses for a class of 595 seniors puts this school in roughly the top 8% of California high schools.
  • And it's a rising stock. UC admissions per senior have climbed three years running — the trend line, not just the snapshot, is moving the right way.
  • The UC surprise: most admits from the middle campuses — most enrollments at Berkeley. The middle campuses said yes far more often — 253 of this class's 322 UC admits came from San Diego, Santa Barbara, Irvine, and Davis. But the campus grads chose most is Berkeley: 32 of its 45 admits took the seat. Those offers are rare — and when kids from here win one, they keep it.
  • Families don't leave. 98% of students who start the year here finish it here — top-tier retention statewide. Kids stay; that tells you something no test score does.
  • 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.

This is the academic-readiness signal that pairs with UC Reach (post-grad outcomes), stability (retention), and absenteeism (engagement).

Enrollment stability & demand — 2024-25

Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the San Mateo County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.

Families don't leave: 98% of students who start the year finish it here — top-tier retention statewide.

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).

Campus-level totals may count one student admitted to multiple UC campuses more than once; Admit Volume metrics are not the same as UC Reach, which requires unique-student counts. See methodology →

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 54% 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 low yield: students are earning UC admission at high rates and then enrolling elsewhere. The pattern is characteristic of competitive college-preparatory schools where many students choose more selective private colleges or out-of-state flagships over UC — UC functions as a strong backup option rather than a first choice.
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.
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.
