Enrollment stability & demand — 2024-25

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

Best in class — winning on demand and retention.

Temecula Preparatory School outperformed Riverside County on enrollment (school +15.6% vs. county -2.7%) AND maintains 94.8% stability. Replicable model — worth documenting what's working.

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.

Absenteeism is up 7.5 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.

This is the academic-readiness signal that pairs with UC Reach (post-grad outcomes), stability (retention), and absenteeism (engagement). Note: statewide median Math is only ~20% — a school at 20% isn't an outlier; one at 45%+ genuinely is.

UC Yield Rate ⓘ

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 ⓘ

11.1%

8 enrollees / 72 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.

▸Its UC Reach has risen 26 points since 2018.
▸Across the top-6 UC campuses, Temecula Preparatory School is admitting at roughly +8 percentage points above what its average applicant GPA (3.946) alone would predict (30% actual vs. 22% expected). That's a meaningful signal — it can reflect UC's track record with this school's graduates, students presenting strongly in UC's holistic review (essays, EC's, context), or institutional familiarity helping at the margin. The data can't distinguish which, but the pattern itself is real and worth understanding.
▸Senior-class enrollment is up 16% (64→74 from 2018 to 2026), outpacing the peer-group median of +1%.
▸Enrollment has been growing (+0.4%/yr); projects to ~1100 by 2029.

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
UCLA	4.05	13.6%	9.5%	+4.1pp	On target
UC San Diego	3.93	39.3%	21.6%	+17.7pp	Over

UC Davis	4.03	88.9%	33.1%	+55.8pp	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.

⚠ 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.

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.

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.

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.

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.
