SAT / ACT participation
CRDC federal data · 2020-21Bottom 38% 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.
🎓 4-year graduation rate · federal EDFacts
What % of students graduate on time?
Bottom 10% of US high schools by 4-yr grad rate

👩🏫 Teacher workforce · federal CRDC
Teacher experience & reliability
Source: federal Civil Rights Data Collection (CRDC 2017-18 — the most recent vintage that publishes per-school teacher quality fields; the 2020-21 sweep had them suppressed). "Inexperienced" = teachers in their first or second year. "Chronic absence" = teachers absent 10+ days/year.
Enrollment trend & projection
Total enrollment + grade 12, NCES Common Core of Data (2021–2024).
If the recent trend holds…
At its recent rate of -17.6%/year, projecting from 2024's 285 students:
≈ 177 fewer students by 2029 — a real revenue/relevance risk worth getting ahead of.
An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.
Revenue at risk
At $11,547 per student in district revenue, the 177 students projected to be lost by 2029 represent ≈ $2,043,819/year in funding at risk.
District total revenue ÷ enrollment, NCES F-33. Public funding largely follows enrollment, so a shrinking class is a recurring budget hit.
