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.

👩‍🏫 Teacher workforce · federal CRDC

Teacher experience & reliability

% inexperienced teachers (1st-2nd yr)
4.1%
Strong: experienced corps. New teachers rotate through but most have ≥3 years in.
% chronic teacher absence (≥10 days/yr)
15.3%
Elevated. Teacher absence directly affects classroom continuity and student outcomes.

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

Title I Targeted Assistance eligible

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

38.9%
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.

Counselor capacity

Student : Counselor
373:1
Around the US median. Counselors are stretched but functional.
Counselor FTE
5.7
Full-time-equivalent school counselors on staff.
Teacher FTE
93
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 497 in 2021 to 549 in 2024 — over 3 years.
+10.5%

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

If the recent trend holds…

At its recent rate of -0.4%/year, projecting from 2024's 2,109 students:

2025
2,101
2027
2,086
2029
2,071

≈ 38 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 $14,892 per student in district revenue, the 38 students projected to be lost by 2029 represent ≈ $565,896/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.
