How Grissom Es compares with Oklahoma and U.S. medians
What stands out at Grissom Es
Scale and staffing sit near the state mainstream
Grissom Es is neither an extreme outlier in enrollment nor in student-teacher ratio among Oklahoma 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
Grissom Es's 25.7% 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.
Grissom Es is a mid-sized combined-grade school in Tulsa, Oklahoma, enrolling 342 students.
Class loads run somewhat heavier than typical: 18:1 puts it in the larger third of Oklahoma schools by student-teacher ratio.
With 342 students, its enrollment sits close to the Oklahoma median campus size.
Its Resource Investment Index lands in the lower third of 1,778 scored Oklahoma schools.
Its student body is led by White (43%) and Hispanic or Latino (24%) (diversity index 72/100).
Counselor availability sits well past the ASCA benchmark, roughly 342 students sharing each counselor, though short of the most stretched campuses.
Chronic absenteeism is elevated: 25.7% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Its district draws 27.1% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
Among Tulsa's public schools, it stands alongside Ellen Ochoa Es (968 students): Grissom Es is smaller than that campus by headcount and runs heavier classes (18:1 vs 16.4:1).
Tulsa also operates Booker T. Washington Hs (1,302 students) and East Central Hs (1,160 students) alongside Grissom Es.
