- The UC pipeline here is real. 163 admissions to the top six UC campuses for a class of 275 seniors puts this school in roughly the top 6% of California high schools.
- And it's a rising stock. UC admissions per senior have climbed three years running — the trend line, not just the snapshot, is moving the right way.
- Where grads land in the UC system: UC San Diego. More graduates enroll at UC San Diego than any other UC. Berkeley and UCLA admitted 28 of this class's 779 UC applications — elite admits are rare everywhere, and the strong middle campuses are where most real outcomes happen.
- Families don't leave. 96% of students who start the year here finish it here — top-tier retention statewide. Kids stay; that tells you something no test score does.
- Worth asking about on a tour: counselor load. One counselor serves about 350 students here — above the 250-to-1 level counseling experts recommend. Ask how junior-year college advising actually gets covered.

SAT / ACT participation
CRDC federal data · 2020-2172nd percentile by test-taker volume
Source: federal Civil Rights Data Collection (CRDC 2020-21). Volume — not score — is what's reported here. A higher count means more students at this school are entering the college admissions pipeline. Note: 2020-21 was COVID-disrupted; some districts (especially those that stayed remote longer) report unusually low or zero takers.

🏛️ Federal Title I context
Lower-need school
Not Title I eligible (FRPL < 25%)
<25% of students qualify for free/reduced lunch. Well below the Title I threshold; expect a higher-income student body on average.
Source: NCES Common Core of Data, free/reduced-price lunch eligibility. The actual Title I designation is a district decision and may differ from eligibility — but the federal eligibility math is what we show here. We don't claim to assert whether the district formally chose to enroll this school in Title I.
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.

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

Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the San Mateo County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Mills High School's enrollment is shrinking 3.0× the county rate (school -15.8% vs. county -5.3%). Stability of 96.5% 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.
39 of 1,130 students who enrolled at Mills High School this year didn't maintain continuous enrollment (3.5% 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.
District financial profile — San Mateo 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: 85.0%
Federal: 3.6%
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 San Mateo 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).
