How Williams Medical Prep High Sch compares with Illinois and U.S. medians
What stands out at Williams Medical Prep High Sch
Small campus with unusually lean teacher staffing
Williams Medical Prep High Sch sits near the smaller end of the Illinois enrollment distribution while also reporting a lower student-teacher ratio than most state schools. That pairing is consistent with a compact, teacher-dense setting, though small scale can limit the number of specialized courses or support roles a campus can sustain. The program and staffing sections below show whether the lean ratio extends beyond classroom teachers into broader student services.
Attendance is the dominant support signal
Williams Medical Prep High Sch's 60.8% chronic-absence rate is more consequential than a generic staffing label: at least one quarter of students missed 10% or more of school days in the 2021-22 collection. That level can affect instruction, counseling demand, and continuity even when other reported resources look ordinary. The dataset records the scale of absence but not its causes, so it should prompt a current-year question rather than a conclusion about school management.
