UC Application Reach ⓘ

124.3%

133 applications

Most seniors are applying to at least one of the six most selective UCs (applications counted at each campus).

In context: CA median 78.3% · Top 10% statewide ≥ 245.8% · Orange Co. Top 10% ≥ 294.1% · higher than 69% of CA HS.

UC Yield Rate ⓘ

10.0%

3 enrolled of 30 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 ⓘ

2.8%

3 enrollees / 107 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.

Admit rate vs. CA peer average, by campus ⓘ

How does this school's admit rate at each UC compare to other CA schools whose applicant pool averages the same GPA? Based on 2024 (latest GPA available).

Campus	Applicant GPA (avg)	Actual admit rate	CA peer avg	Δ	Verdict
UCLA	4.04	12.5%	9.3%	+3.2pp	On target
UC San Diego	3.88	20.8%	24.1%	-3.3pp	On target
UC Santa Barbara	3.86	21.1%	27.9%	-6.9pp	Under
UC Irvine	3.90	30.0%	22.8%	+7.2pp	Over
UC Davis	3.93	41.7%	30.7%	+10.9pp	Over

"Applicant GPA" is the average GPA of this school's UC applicant pool — not an individual student GPA. "CA peer avg" is the application-weighted statewide admit rate at this school-pool GPA, fit separately per campus. At any given pool GPA, real admit rates span widely (UCSD ranges 8% → 65% across CA schools) because UCs use comprehensive review — context-of-opportunity, geography, demographics, and applicant essays all weigh in beyond GPA. A large negative residual flags this school is admitted at a meaningfully lower rate than other CA schools at the same pool GPA — not that students here were "rejected at expected rate X." "Over" / "Under" use a ±5-point band. Campuses with fewer than 5 applicants are omitted.

Where Rosary Academy sits vs. all California schools ⓘ

Overall, this school admits its UC applicants in line with what their GPAs predict (23.9% actual vs. 21.9% expected), based on 2024 data.

⚠ 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.
