Across schools that reported staffing, the median student–teacher ratio is 23.5:1, higher than the statewide school median of 21.6:1. A ratio counts classroom-teacher FTE against total enrollment, so specialized programs and part-time staffing can move it; ask schools for actual class sizes by grade.
