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.
Enrollment growth is beating Los Angeles County (+25.9% vs. -8.2%), but 572 of 3018 students didn't maintain continuous enrollment. Why are families leaving once enrolled? Chronic absenteeism is rising (28.3%, +9.5 pts since 2016-17) — a watch signal worth monitoring as a leading indicator.
572 of 3,018 students who enrolled at Lancaster High School this year didn't maintain continuous enrollment (19.0% non-stability). Mid-year transfers, dropouts, and other exits are all counted.
Stability by student group
Nearest peer high schools
Source: California Department of Education, Stability Rate 2024-25. 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 9.4 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 — Antelope Valley 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.
Local: 21.3%
Federal: 12.0%
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 Antelope Valley 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).
