82th percentile nationally

SAT / ACT participation
CRDC federal data · 2020-2167th 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.

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.

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 in the typical CA HS range. Worth monitoring alongside the demand and retention signals above.

Enrollment stability & demand — 2024-25
Two complementary signals: retention (do students stay once enrolled?) and demand (are families choosing the school?). Read against the Marin County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Enrollment -8.2% vs. county +7.3% — losing far faster than the county. Each enrolled family matters more, but the engine of new enrollment is breaking down.
62 of 1,502 students who enrolled at Tamalpais High School this year didn't maintain continuous enrollment (4.1% non-stability). Mid-year transfers, dropouts, and other exits are all counted.
Stability by student group

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 — Tamalpais 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: 85.9%
Federal: 3.2%
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 Tamalpais 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).
