- 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.

Objective, government-grade data — no school pays us for placement.
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.

Overall, Mary Star of the Sea High School's UC Reach is higher than 48% of California high schools (1105 ranked).
Private-school figures come from the California Private School Affidavit. Per CDE, inclusion in private-school data is not an evaluation, approval, or endorsement of a school.
GPA figures reflect 2024 — UC has not yet released applicant/admit GPA for 2025.
UC Outcomes Trend — 2024–2025
Class size from CDE grade 12 enrollment. Campus-level data: applicant and admit totals count a student once at EACH campus. A senior admitted to UCLA and UC San Diego adds 2 to the admit total, so the total can exceed the senior class — that is the metric working as defined, not an error. The admit RATE is unaffected: both its numerator and denominator are campus-level.
