Test-taking intensity

0.0

takers per 100 students in grades 9-12

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)

8.6%

Strong: experienced corps. New teachers rotate through but most have ≥3 years in.

% chronic teacher absence (≥10 days/yr)

0.0%

Strong attendance culture among teachers.

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

Lower-need school

Not Title I eligible (FRPL < 25%)

22.3%

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)

<25% of students qualify for free/reduced lunch. Well below the Title I threshold; expect a higher-income student body on average.

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

50.0%

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

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 →

A small or specialty program — naive trend math doesn't capture the school's full picture. Read the trend as directional, not predictive.

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