Naperville Cusd 203 student-counselor ratio is 262:1: slightly below the ~408 national average, within the typical range for U.S. public districts
student-counselor ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE counselors against total enrollment, districts that contract intervention or social-emotional staff outside the counselor classification may be under-counted Sitting just under the national figure still leaves meaningful room for sub-unit variation that the aggregate number hides. Variation between sub-units within Naperville Cusd 203 is typically wider than the Naperville Cusd 203-aggregate figure suggests.
Naperville Cusd 203 chronic absenteeism rate is 18.3%: slightly below the ~28 national average, aligned with the national post-pandemic baseline of roughly 28% chronic absenteeism
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 Sitting just under the national figure still leaves meaningful room for sub-unit variation that the aggregate number hides. Variation between sub-units within Naperville Cusd 203 is typically wider than the Naperville Cusd 203-aggregate figure suggests.
