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)
12.0%
Typical mix. Watch the trend — high turnover can compound.
% chronic teacher absence (≥10 days/yr)
36.0%
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

Title I Targeted Assistance eligible

35-39% FRPL — qualifies for Title I Targeted Assistance

37.8%
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)

35-39% of students qualify for free/reduced lunch. The school can receive Title I funds targeted to identified students (not schoolwide).

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.

Chronic absenteeism

Share of students absent 15+ days
22.9%
Elevated above the national average (~16%). Worth understanding — chronic absence compounds into dropout risk, transfer-out risk, and revenue loss.
Students absent 15+ days
60
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 →

Source: U.S. Department of Education, Civil Rights Data Collection 2020–2021. Rate = students chronically absent ÷ 2024 total enrollment.

Counselor capacity

Student : Counselor
131:1
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
25
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 69 in 2021 to 59 in 2024 — over 3 years.
-14.5%

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

If the recent trend holds…

At its recent rate of +0.9%/year, projecting from 2024's 262 students:

2025
264
2027
269
2029
274

An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.

Revenue upside

At $28,933 per student in district revenue, the 12 students projected to be gained by 2029 represent ≈ $347,196/year in additional funding.

District total revenue ÷ enrollment, NCES F-33. Public funding largely follows enrollment, so a shrinking class is a recurring budget hit.
