District-Level NCES Analysis
Chsd 99 operates 2 public schools serving 4,775 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. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Dupage County.
Per-pupil expenditure runs $26,343 according to the NCES F-33 School District Finance Survey, among the top 85 of 845 Illinois districts by per-pupil spending. See how Illinois compares in our national per-pupil spending analysis. The funding mix is 73.9% local, 23.0% state, and 3.0% federal, a local-revenue-heavy mix that leaves the district more exposed to property-tax swings and local ballot measures than state-funded peers. The district's equity score is 35/100, ranked #444 of 759 in Illinois against a state average of 38, in line with the typical spread seen across the state for how evenly funding reaches its schools.

Comm H S Dist 99 - South High Sch accounts for 54.3% of all Chsd 99 student enrollment
That is an overwhelming concentration, leaving the rest of Chsd 99 a distant remainder — means Chsd 99-wide averages can mask substantial variation outside the largest entity. Grade band: high. The share measures enrollment concentration only; it does not establish how the district allocates programs, capital, or staff. Because it contains a majority of the affected population, enrollment-weighted aggregates will sit closer to this entity's reported fields than to those of smaller peers; an unweighted entity count answers a different question.
Chsd 99 student-counselor ratio is 233:1 — low (typically associated with meeting or exceeding the American School Counselor Association (ASCA) recommended 250:1 benchmark, which correlates with stronger college and career counseling capacity)
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 Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
Chsd 99 chronic absenteeism rate is 23.9% — near the typical range (US average ~28) — 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 Variation between sub-units within Chsd 99 is typically wider than the Chsd 99-aggregate figure suggests.
