Enrollment stability & demand — 2024-25

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

Critical
Sharp demand downturn hidden by elite retention.

Los Altos High School's enrollment is shrinking 2.4× the county rate (school -20.0% vs. county -8.2%). Stability of 90.6% means every family you keep is one fewer; the leverage is at recruitment, not retention. This is the case the high stability number alone would hide.

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.

This is the academic-readiness signal that pairs with UC Reach (post-grad outcomes), stability (retention), and absenteeism (engagement).

F-33 is a district-level federal filing — it reflects the Hacienda la Puente 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).

Los Altos High School — Enrollment & Outcomes Snapshot

Public · Hacienda Heights · vs. 10 most similar nearby schools

  • On UC Reach, Los Altos High School sits near the bottom of its similar-school group (ranked #10 of 11): 12% vs. a peer median of 17%.
  • Its UC Reach has slipped 2 points since 2018 — worth watching.
  • Across the top-6 UC campuses, Los Altos High School is admitting at roughly +7 percentage points above what its average applicant GPA (3.865) alone would predict (28% 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 down 20% (460→368 from 2018 to 2026), trailing the peer-group median of -14%.
  • At its recent rate (-1.4%/yr), enrollment projects to ~1520 by 2029 — about 66 fewer students than today.

Enrollment projection

1586 students (2026)

That's about 66 fewer students. At per-student funding of $ per student, that's roughly $0 in annual state funding at risk.

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 3.88 9.7% 11.6% -2.0pp On target
UC San Diego 3.87 48.6% 23.0% +25.7pp 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 Los Altos High School sits vs. all California schools

Overall, this school admits its UC applicants 6.6 points above what their GPAs predict (28.5% actual vs. 21.8% 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.
Fewer than 15% of seniors are earning UC admission. This may reflect a high non-UC college-going rate, significant A-G completion gaps, or an early-stage UC pipeline. A deeper review of A-G readiness and counseling capacity is warranted.
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.
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.
