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.

Rosary Academy — Enrollment & Outcomes Snapshot

Private · Catholic · Fullerton · vs. 10 most similar nearby schools

▸On UC Reach, Rosary Academy sits in the middle of its similar-school group (ranked #4 of 10): 28% vs. a peer median of 16%.
▸Rosary Academy's UC Reach has declined meaningfully from a peak of 42% in 2023 to 28% in 2025 — a 14-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.
▸Senior-class enrollment is up 34% (80→107 from 2020 to 2025), outpacing the peer-group median of -7%.
▸Enrollment has been growing (+3.3%/yr); projects to ~509 by 2028.

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

Combining the school's applicant pool GPA, admit pool GPA, actual admit rate, and statewide CA admit rates by individual GPA band, we can read which GPA tiers tend to get in — and which don't.

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).

† = 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 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.

Students are earning UC admission but enrolling elsewhere at a notable rate. This may reflect competition from private colleges, out-of-state flagships, cost considerations, or UC campus fit. Student outcome surveys can clarify.

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: 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.
