US high schools reporting SAT/ACT participation

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.

🏛️ Federal Title I context

Title I Targeted Assistance eligible

35-39% FRPL — qualifies for Title I Targeted Assistance

39.2%
FRPL rate — % of students who qualify for the federal Free or Reduced-Price Lunch program. This is the underlying federal income-eligibility signal Title I designations are computed from (ESEA Sec. 1113).
0% (no FRPL) 35% TA · 40% Schoolwide 100% (universal FRPL)

35-39% of students qualify for free/reduced lunch. The school can receive Title I funds targeted to identified students (not schoolwide).

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.

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 $25,346/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.

Chronic absenteeism

Share of students absent 15+ days
12.7%
Roughly average. The national post-COVID rate climbed to ~16% nationwide; this school is in the middle of the pack.
Students absent 15+ days
227
Federal definition: absent (excused or unexcused) for at least 15 of ~180 school days — about 10% of the school year.

Why this matters to enrollment: Chronic absence is the strongest early indicator of dropout, transfer-out, and family disengagement. A school's absenteeism trend forecasts its enrollment trend 1-3 years out.

Source: U.S. Department of Education, Civil Rights Data Collection 2020–2021. Rate = students chronically absent ÷ 2024 total enrollment.

Counselor capacity

Student : Counselor
892:1
Well above the US median — a real constraint on individualized college and course planning.
Counselor FTE
2.0
Full-time-equivalent school counselors on staff.
Teacher FTE
66
Full-time-equivalent classroom teachers.

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

Grade 12 went from 298 in 2021 to 399 in 2024 — over 3 years.
+33.9%

Total enrollment + grade 12, NCES Common Core of Data (2021–2024).

If the recent trend holds…

At its recent rate of +10.4%/year, projecting from 2024's 1,784 students:

2025
1,969
2027
2,400
2029
2,924

An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.

Revenue upside

At $12,580 per student in district revenue, the 1,140 students projected to be gained by 2029 represent ≈ $14,341,200/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.
