How Horizon Sci Acad - Southwest Chtr compares with Illinois and U.S. medians
Smaller classes than state median
11.9:1 - 2.1 below the Illinois state median of 14:1, indicating smaller average class loads than typical schools in the state.
Horizon Sci Acad - Southwest Chtr combines an upper-tier Illinois enrollment footprint with a student-teacher ratio that is lower than most state peers. Large schools often gain program breadth from scale, but they do not automatically retain this level of teacher staffing. Here, the two measures point in the same favorable operational direction: a large student body without a correspondingly large reported class load. The ratio remains a campus average, not a promise about every classroom.
Horizon Sci Acad - Southwest Chtr's 33.8% 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.
