🎓 Academic rigor
AP + advanced-course offerings
Elite — exceptional AP + advanced course breadth
90th 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 · 2020-2183th percentile 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?
Top 2.3% of US high schools by 4-yr grad rate
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
Lower-need school
Not Title I eligible (FRPL < 25%)
<25% of students qualify for free/reduced lunch. Well below the Title I threshold; expect a higher-income student body on average.
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.
🏛️ Your state's public flagship
Stony Brook University
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 $18,784/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.
Source: IPEDS admissions, tuition & enrollment + College Scorecard net price. Flagship = the state's primary public research university.
💰 Pay for college in New York
New York's public scholarships
New York's Excelsior Scholarship makes SUNY and CUNY tuition-free for middle-income families — there's no GPA or test gate, but you commit to staying in New York after you graduate.
Tuition-free SUNY/CUNY for NY families under $125k AGI — no GPA or test gate, but you must stay on track and live in New York after graduating. (Stay on-track (30 credits/yr); live & work in NY afterward for the years you received it.)

Chronic absenteeism
Why this matters to enrollment: A low chronic-absence rate is the cleanest school-level signal of strong family connection, classroom culture, and student engagement — all upstream drivers of enrollment stability. 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.
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 -0.9%/year, projecting from 2024's 846 students:
≈ 36 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 $32,050 per student in district revenue, the 36 students projected to be lost by 2029 represent ≈ $1,153,800/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.
