District-Level NCES Analysis
Cusd 4 operates 3 public schools serving 664 students, placing it among the smallest districts in Illinois. The school portfolio breaks down into 1 combined, 1 elementary, 1 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 Adams County.
Per-pupil expenditure runs $10,612 according to the NCES F-33 School District Finance Survey, among the bottom 85 of 848 Illinois districts by per-pupil spending. See how Illinois compares in our national per-pupil spending analysis. The funding mix is 47.2% local, 44.3% state, and 8.5% federal, a balanced mix across local, state, and federal sources, spreading budget risk across funding cycles rather than concentrating it in one. The district's equity score is 29/100, ranked #586 of 763 in Illinois against a state average of 38, notably less even than the typical district in the state for how evenly funding reaches its schools.
a 376:1 student-counselor ratio, well above the ASCA benchmark though still under the roughly 408:1 national average, and 23.6% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 96.1% White, 2.3% Hispanic or Latino, 1.0% African American across the district's schools. Its most demographically mixed campus is Unity High School, with a diversity index of 12.9/100.
Its largest campus is Unity Elementary School, enrolling 296 students (44% of the district's total enrollment).
Unity Elementary School accounts for 44.0% of all Cusd 4 student enrollment
That dominant concentration means Cusd 4-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.
Cusd 4 student-counselor ratio is 376:1 — high (typically associated with staffing constraints that limit per-student counselor time; CRDC data shows higher ratios cluster in larger urban systems)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
Cusd 4 chronic absenteeism rate is 23.6% — 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 Cusd 4 is typically wider than the Cusd 4-aggregate figure suggests.
