How Charlo High School compares with Montana and U.S. medians
What stands out at Charlo High School
Scale and staffing sit near the state mainstream
Charlo High School is neither an extreme outlier in enrollment nor in student-teacher ratio among Montana 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
Charlo High School's 41.3% 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.
