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)
36.1%
Elevated — a quarter or more of teachers are in years 1-2. Often correlates with school instability.
% chronic teacher absence (≥10 days/yr)
52.2%
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

Mixed-income school

Below Title I eligibility threshold (FRPL < 35%)

32.1%
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)

25-34% of students qualify for free/reduced lunch. Below the federal Title I threshold but a meaningful share of the population is income-eligible for free lunch.

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

Share of students absent 15+ days
9.0%
Below 10% — strong attendance culture. Chronic absence is a leading indicator of dropout and disengagement; a low rate signals families staying connected to the school.
Students absent 15+ days
45
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: 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

Student : Counselor
251:1
Above the ASCA 250:1 target but below the US median (~430:1). Capacity is workable.
Counselor FTE
2.0
Full-time-equivalent school counselors on staff.
Teacher FTE
42
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 154 in 2021 to 131 in 2024 — over 3 years.
-14.9%

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

If the recent trend holds…

At its recent rate of -5.0%/year, projecting from 2024's 502 students:

2025
477
2027
430
2029
388

≈ 114 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 $23,992 per student in district revenue, the 114 students projected to be lost by 2029 represent ≈ $2,735,088/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.
