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)

5.9%

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

% chronic teacher absence (≥10 days/yr)

82.4%

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

3.8%

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

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.

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.
