Overall, Carondelet High School's UC Reach is higher than 91% of California high schools (1105 ranked).

UC Application Reach ⓘ

203.9%

422 applications

Strong UC pursuit. The typical senior is applying to about 2 top-6 UC campuses — a signal of a college-driven student body.

In context: CA median 78.3% · Top 10% statewide ≥ 245.8% · Contra Costa Co. Top 10% ≥ 323.6% · higher than 85% of CA HS.

UC Yield Rate ⓘ

23.7%

27 enrolled of 114 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 ⓘ

13.0%

27 enrollees / 207 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.

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
UC Berkeley	4.01	20.3%	15.0%	+5.3pp	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.

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 55% 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.

UC Reach has improved meaningfully compared to the prior year — a positive trajectory worth monitoring and reinforcing.

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.
