Enrollment stability & demand — 2024-25

Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Orange County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.

Tracking baseline
Tracking county on both axes.

Enrollment and retention both close to Orange County baseline. The demographic tide is the main mover; no internal break in the system, but no outperformance either.

Benchmarks limited to non-virtual public & charter HS with ≥100 cumulative enrollees so by-design-high-churn continuation schools don't dominate the bottom of the distribution. Cumulative enrollment counts every student on the rolls during the year, so it can exceed peak-day enrollment.

Chronic absenteeism — 2024-25

Share of students missing 10% or more of expected attendance — the leading indicator that often precedes the demand decline shown above. Families disengaging tend to raise absenteeism first, then formally leave. Basis: grades 9–12.

F-33 is a district-level federal filing — it reflects the Capistrano Unified as a whole, not this individual school's books. Revenue mix shows where the district's dollars come from (state aid dominates in CA via LCFF). Instruction share is current expenditure on instruction ÷ total current expenditure (national benchmark ~60%). Long-term debt is end-of-year outstanding (mostly facilities bonds).

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?

Campus Applicant GPA (avg) Actual admit rate CA peer avg Δ Verdict
UC Berkeley 4.03 11.4% 13.1% -1.8pp On target

"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 Aliso Niguel High School sits vs. all California schools

Overall, this school admits its UC applicants in line with what their GPAs predict (25.6% actual vs. 22.2% expected).

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 solid. A meaningful share of the senior class is achieving UC admission, and there is likely room to grow both application volume and admission outcomes.
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.
Berkeley/UCLA admit volume is modest relative to overall UC reach. This is common and reflects the highly selective nature of those campuses, but may be a target area for the school's highest-performing students.
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.
