Academic rigor
AP + advanced-course offerings
Elite — exceptional AP + advanced course breadth
76th percentile nationally
Gifted/talented program
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 · 2020-2194th 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 0.7% 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.
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
University of Maryland-College Park
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 $15,678/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.
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.
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 -2.3%/year, projecting from 2024's 1,383 students:
≈ 152 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 $20,227 per student in district revenue, the 152 students projected to be lost by 2029 represent ≈ $3,074,504/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.
