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)
2.9%
Strong: experienced corps. New teachers rotate through but most have ≥3 years in.
% chronic teacher absence (≥10 days/yr)
5.7%
Around the national average. Worth watching.

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%)

18.2%
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)

<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

in-state tuition/yr · $35,124 out-of-state
1270–1510
SAT 25–75 · ACT 29–34

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 $14,355/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
2.8%
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
13
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
231:1
Below the ASCA 250:1 recommendation — strong capacity for college planning, course selection, and student supports.
Counselor FTE
2.0
Full-time-equivalent school counselors on staff.
Teacher FTE
32
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 105 in 2021 to 123 in 2024 — over 3 years.
+17.1%

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

If the recent trend holds…

At its recent rate of -1.1%/year, projecting from 2024's 462 students:

2025
457
2027
447
2029
438

≈ 24 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 $16,618 per student in district revenue, the 24 students projected to be lost by 2029 represent ≈ $398,832/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.
