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)
11.0%
Typical mix. Watch the trend — high turnover can compound.
% chronic teacher absence (≥10 days/yr)
29.7%
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

High-poverty school

Title I Schoolwide eligible

84.1%
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)

≥75% of students qualify for free/reduced lunch. These schools qualify for the highest tier of federal Title I funding and typically receive extra wraparound services. Academic outcomes vary widely — check the state assessment + grad-rate tiles.

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
328:1
Above the ASCA 250:1 target but below the US median (~430:1). Capacity is workable.
Counselor FTE
5.0
Full-time-equivalent school counselors on staff.
Teacher FTE
76
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 480 in 2021 to 423 in 2024 — over 3 years.
-11.9%

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

If the recent trend holds…

At its recent rate of -4.6%/year, projecting from 2024's 1,638 students:

2025
1,563
2027
1,422
2029
1,294

≈ 344 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 $22,591 per student in district revenue, the 344 students projected to be lost by 2029 represent ≈ $7,771,304/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.
