California College-Going Rate
College-going rate: —
The share of 2022-23 graduates who enrolled at a college anywhere in the U.S. within 12 months, per the National Student Clearinghouse match the California Department of Education publishes.
CDE masks small groups. It suppresses every figure for a school whose graduating class is 10 students or fewer, so no rate is published for Sierra High (Continuation)’s 2022-23 class. The figure exists — it is withheld, not missing.
Source: California Department of Education, College-Going Rate (DataQuest) ↗, cohort 2022-23, posted 17-Sep-2025. Data file: cgr12mo23.txt ↗ (and the 16-month file ↗). CDE builds the rate by matching California high school completers to National Student Clearinghouse enrollment records; we publish CDE’s aggregates and hold no student-level data.
SAT / ACT participation
CRDC federal data · 2020-21Source: 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.
4-year graduation rate · federal EDFacts
What % of students graduate on time?

Federal Title I context
Mixed-income school
Below Title I eligibility threshold (FRPL < 35%)
25-34% of students qualify for free/reduced lunch. Below the federal Title I threshold but a meaningful share of the population is income-eligible for free lunch.
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.
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
Source: California Department of Education, Census Day Enrollment 2025-26 (HS grades 9–12). Δ shown when shift is ≥1 pt since 2023-24. Categories below 0.5% omitted.
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 18.6 pp since 2016-17. A rising absenteeism trend often precedes formal departure — worth investigating which subgroups are driving it.
Source: California Department of Education, Chronic Absenteeism 2024-25. Benchmarks limited to non-virtual public & charter HS with ≥100 eligible students. CDE didn't publish a usable 2019-20 file (COVID).

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.
Enrollment growth is beating Mono County (+0.0% vs. -42.4%), but 10 of 13 students didn't maintain continuous enrollment. Why are families leaving once enrolled? Chronic absenteeism is also at 92.3% (up +18.6 pts from 2016-17) — engagement and demand are both signaling decline.
10 of 13 students who enrolled at Sierra High (continuation) this year didn't maintain continuous enrollment (76.9% non-stability). Mid-year transfers, dropouts, and other exits are all counted.
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).
