63rd 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 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.

Your state's public flagship
University of Massachusetts-Amherst
The in-state tuition gap is the flagship's biggest draw — most in-state families pay far less than the out-of-state sticker. Average net price after aid runs about $22,383/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.

Chronic absenteeism
Why this matters to enrollment: Chronic absence is the most reliable early indicator that a student will leave a school — either by transferring out, dropping out, or matriculating to a charter or private alternative. At this level, today's absentees become next year's enrollment loss and the year-after's revenue loss.
Source: U.S. Department of Education, Civil Rights Data Collection 2020–2021. Rate = students chronically absent ÷ 2021 total enrollment.
Counselor capacity
Source: U.S. Department of Education, Civil Rights Data Collection 2020-2021. Counselor ratio = the school's most recent total enrollment ÷ counselor FTE. The American School Counselor Association (ASCA) recommends a 250:1 maximum; the US national median across schools with on-staff counselors is roughly 430:1.
Enrollment trend & projection
Total enrollment + grade 12, NCES Common Core of Data (2021–2024).
If the recent trend holds…
At its recent rate of -4.2%/year, projecting from 2024's 426 students:
≈ 83 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 $13,375 per student in district revenue, the 83 students projected to be lost by 2029 represent ≈ $1,110,125/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.
