How Clay Elem School compares with Illinois and U.S. medians
What stands out at Clay Elem School
Scale and staffing sit near the state mainstream
Clay Elem School is neither an extreme outlier in enrollment nor in student-teacher ratio among Illinois schools. Its profile therefore turns on the other dimensions rather than on scale alone: economic need, counselor coverage, program access, attendance, and district finance. This middle placement is useful because it prevents the campus from being mislabeled as unusually large, small, crowded, or teacher-dense when the federal comparison does not support that claim.
Attendance is the dominant support signal
Clay Elem School's 46.5% 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.
Clay Elem School is a mid-sized combined-grade school in Chicago, Illinois, enrolling 578 students.
Class loads run somewhat heavier than typical: 14.4:1 puts it in the larger third of Illinois schools by student-teacher ratio.
Enrollment of 578 puts it in the larger third of Illinois schools by headcount.

Its student body is led by Hispanic or Latino (68%) and African American (24%) (diversity index 48/100).
Counselor access is stretched at roughly 578 students per counselor, well above the ASCA-recommended 250:1 ceiling.
Chronic absenteeism is elevated: 46.5% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
