  • Where graduates go, as the school itself publishes it. Mary Star of the Sea High School publishes where its graduates go (Class of 2021): 107 colleges, including Northeastern University, University of Illinois Urbana-Champaign, University of Southern California, University of Washington.
  • Most grads aim beyond the UC system. Seniors file only ~1.2 UC applications each — families here mostly target CSU, private, or out-of-state colleges, so judge this school on more than its UC numbers.
  • Worth asking admissions: the school profile. Reach doesn't yet show this school's SAT/ACT or AP results. Every private school produces a counselor's "school profile" for colleges, and most post it online — ask admissions for it. How a school answers says as much as the numbers.

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.

† = UCOP-suppressed (count below 3 students, hidden for privacy — actual value is 0, 1, or 2, not necessarily zero). 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 is measured against the whole senior class. 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 has improved meaningfully compared to the prior year — a positive trajectory worth monitoring and reinforcing.
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.
