🎓 Academic rigor
AP + advanced-course offerings
Strong — solid AP program + advanced courses
58th 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 45% 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?
90th percentile nationally
Source: federal EDFacts ACGR (Adjusted Cohort Graduation Rate), 2019 vintage via Urban Institute. EDFacts publishes a range (low-high) to preserve privacy on small cohorts; we display the midpoint.
👩🏫 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.
🏛️ Federal Title I context
High-poverty school
Title I Schoolwide eligible
≥75% of students qualify for free/reduced lunch. These schools qualify for the highest tier of federal Title I funding and typically receive extra wraparound services. Academic outcomes vary widely — check the state assessment + grad-rate tiles.
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.
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. For school leaders: an Enrollment Trend Audit traces this dynamic forward →
Source: U.S. Department of Education, Civil Rights Data Collection 2020–2021. Rate = students chronically absent ÷ 2024 total enrollment.
Enrollment trend & projection
Total enrollment + grade 12, NCES Common Core of Data (2021–2024).
If the recent trend holds…
At its recent rate of +2.6%/year, projecting from 2024's 1,253 students:
An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.
Revenue upside
At $17,097 per student in district revenue, the 170 students projected to be gained by 2029 represent ≈ $2,906,490/year in additional funding.
District total revenue ÷ enrollment, NCES F-33. Public funding largely follows enrollment, so a shrinking class is a recurring budget hit.
