District-Level NCES Analysis
Dupage Hsd 88 operates 2 public schools serving 3,919 students, placing it among the smallest districts in Illinois. The school portfolio breaks down into 2 high schools, a small enough portfolio that most families will interact with nearly every campus in the district at some point.

That is an overwhelming concentration, leaving the rest of Dupage Hsd 88 a distant remainder — means Dupage Hsd 88-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.
Dupage Hsd 88 student-counselor ratio is 274:1 — near the typical range (US average ~408) — 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 Variation between sub-units within Dupage Hsd 88 is typically wider than the Dupage Hsd 88-aggregate figure suggests.
Dupage Hsd 88 chronic absenteeism rate is 40.6% — high (typically associated with higher-than-average disruption; recent CRDC data showed elevated rates persisting after pandemic-era schooling changes)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
