District-Level NCES Analysis
Cass Sd 63 operates 2 public schools serving 775 students, placing it among the smallest districts in Illinois. The school portfolio breaks down into 1 combined, 1 elementary 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 $15,702 according to the NCES F-33 School District Finance Survey, in the lower half of 848 Illinois districts by per-pupil spending. See how Illinois compares in our national per-pupil spending analysis. The funding mix is 69.4% local, 24.1% state, and 6.6% 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 31/100, ranked #541 of 763 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.
a 616.5:1 student-counselor ratio, above both the ASCA benchmark and the roughly 408:1 national average, and 24.8% chronic absenteeism from the 2021-22 Civil Rights Data Collection.

Concord Elem School accounts for 59.4% of all Cass Sd 63 student enrollment
That is an overwhelming concentration, leaving the rest of Cass Sd 63 a distant remainder — means Cass Sd 63-wide averages can mask substantial variation outside the dominant entity. Grade band: combined. 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.
Cass Sd 63 student-counselor ratio is 617:1 — well above typical (typically associated with unusually large scale or acute resource constraints)
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 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.
Cass Sd 63 chronic absenteeism rate is 24.8% — 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 Cass Sd 63 is typically wider than the Cass Sd 63-aggregate figure suggests.
