Riverside Elementary District (4257) chronic absenteeism rate is 47.0% — well above typical (typically associated with unusually large scale or acute resource constraints)

chronic absenteeism rate is the simplest comparative metric but it does not capture the full picture: a student is chronically absent if they miss ≥10% of enrolled days for any reason, illness, family obligations, or disengagement Values this far above typical often signal acute resource constraints or a structurally different scale than most peers — worth reading alongside the underlying counts, not the ratio alone.
