Enrollment stability & demand — 2024-25

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

Action needed
Demand declining faster than county; retention only average.

Enrollment is shrinking faster than Lassen County (school +12.3% vs. county +21.6%) with stability (83.9%) near the county median. Two problems compounding — the recruitment side is the higher-leverage starting point.

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

SBAC academic outcomes — grade 11, 2025

Share of grade-11 students meeting or exceeding the California standard on Smarter Balanced ELA and Math. 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.

District financial profile — Lassen Union High (FY2020)

From 4 years of NCES F-33 filings (the federally-mandated district finance survey). Public schools don't have their own books — the district does. These figures show the financial scale, revenue dependence, instruction-vs-overhead mix, and long-term debt that shape what a school can sustain.

Source: NCES F-33 Annual Survey of School System Finances (Urban Institute Education Data API). Latest year currently published: FY2020. F-33 is a district-level federal filing — it reflects the Lassen Union High 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 Davis 3.90 55.6% 32.3% +23.3pp 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.

⚠ 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

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.
UC Reach has declined meaningfully year-over-year. This should be reviewed in context of applicant volume, GPA trends, course rigor changes, and peer-school performance before drawing conclusions.
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.
