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)
7.0%
Strong: experienced corps. New teachers rotate through but most have ≥3 years in.
% chronic teacher absence (≥10 days/yr)
53.8%
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
8.7%
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
25
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
95:1
Below the ASCA 250:1 recommendation — strong capacity for college planning, course selection, and student supports.
Counselor FTE
3.0
Full-time-equivalent school counselors on staff.
Teacher FTE
31
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 75 in 2021 to 79 in 2024 — over 3 years.
+5.3%

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

If the recent trend holds…

At its recent rate of -4.5%/year, projecting from 2024's 286 students:

2025
273
2027
249
2029
228

≈ 58 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 $22,483 per student in district revenue, the 58 students projected to be lost by 2029 represent ≈ $1,304,014/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.
