How Calvin Es compares with Oklahoma and U.S. medians
What stands out at Calvin Es
Small campus with unusually lean teacher staffing
Calvin Es sits near the smaller end of the Oklahoma 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 a relative strength
8.7% of Calvin Es students were chronically absent in the 2021-22 civil-rights collection. On its face, that is a comparatively low historical rate, though this page does not treat it as a current national benchmark or guarantee current-year performance. Here, attendance is a more distinctive signal than the presence or absence of any single specialist role.
