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.

Chronic absenteeism

Share of students absent 15+ days
54.7%
Well above the national average (~16%). At this level, chronic absence becomes a leading driver of enrollment loss as families rotate to other schools.
Students absent 15+ days
233
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 most reliable early indicator that a student will leave a school — either by transferring out, dropping out, or matriculating to a charter or private alternative. At this level, today's absentees become next year's enrollment loss and the year-after's revenue loss. For school leaders: an Enrollment Trend Audit traces this dynamic forward →

Counselor capacity

Student : Counselor

Below the ASCA 250:1 recommendation — strong capacity for college planning, course selection, and student supports.
Counselor FTE

Full-time-equivalent school counselors on staff.
Teacher FTE

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 56 in 2024 — over 3 years.
-25.3%

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

If the recent trend holds…

At its recent rate of -4.3%/year, projecting from 2024's 426 students:

2025
408
2027
373
2029
342

≈ 84 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 $13,375 per student in district revenue, the 84 students projected to be lost by 2029 represent ≈ $1,123,500/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.
