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)
10.0%
Typical mix. Watch the trend — high turnover can compound.
% chronic teacher absence (≥10 days/yr)
39.2%
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.

Chronic absenteeism

Share of students absent 15+ days
10.1%
Roughly average. The national post-COVID rate climbed to ~16% nationwide; this school is in the middle of the pack.
Students absent 15+ days
78
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. 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
770:1
Well above the US median — a real constraint on individualized college and course planning.
Counselor FTE
1.0
Full-time-equivalent school counselors on staff.
Teacher FTE
71
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 81 in 2021 to 95 in 2024 — over 3 years.
+17.3%

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

If the recent trend holds…

At its recent rate of -0.3%/year, projecting from 2024's 770 students:

2025
768
2027
764
2029
760

≈ 10 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 $14,780 per student in district revenue, the 10 students projected to be lost by 2029 represent ≈ $147,800/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.
