- About 2 in 3 students read and write at grade level. On the state's own 11th-grade test, 67% met or exceeded the college-readiness bar — well above the state as a whole (statewide: 54%).
- Most grads aim beyond the UC system. Seniors file only ~0.7 UC applications each — families here mostly target CSU, private, or out-of-state colleges, so judge this school on more than its UC numbers.
- Worth asking about: the recent trend. UC admissions per senior have slipped for three straight years. Ask the school what changed — counseling, course access, or just class-size shifts.

🎓 Academic rigor

Elite — exceptional AP + advanced course breadth
80th percentile nationally
Source: federal Civil Rights Data Collection (CRDC 2020-21). CRDC reports what's offered + enrolled — it doesn't collect AP exam pass rates (College Board owns that data and doesn't release it school-level).
SAT / ACT participation
CRDC federal data · 2020-21Bottom 23% 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
Title I Targeted Assistance eligible
35-39% FRPL — qualifies for Title I Targeted Assistance
35-39% of students qualify for free/reduced lunch. The school can receive Title I funds targeted to identified students (not schoolwide).
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.

Student composition — 2025-26
HS grades 9–12 racial/ethnic composition and program subgroups, from CDE Census Day Enrollment. Two-year shift shown when ≥1 pt — surfaces how the community served has changed since 2023-24.

Program subgroups

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 14.6 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 Mono County baseline — the demographic tide is moving every CA HS, so a school's gap vs. county is the actionable signal.
Mammoth High School outperformed Mono County on enrollment (school +0.0% vs. county -42.4%) AND maintains 89.2% stability. Replicable model — worth documenting what's working. Chronic absenteeism is rising (27.8%, +14.6 pts since 2016-17) — a watch signal worth monitoring as a leading indicator.
38 of 352 students who enrolled at Mammoth High School this year didn't maintain continuous enrollment (10.8% 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 — Mammoth Unified (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: 77.7%
Federal: 7.4%
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 Mammoth 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).
