District-Level NCES Analysis

CUSD 4 operates 3 public schools serving 664 students, placing it among the smaller districts in Illinois. The school portfolio breaks down into 1 other, 1 elementary, 1 high schools, giving families a clear picture of grade-band coverage before they move, rent, or enrol. Aggregated across those campuses, enrollment totals 672 pupils using the NCES Common Core of Data (CCD) 2022-23 release, and the district is geographically located in Adams County County.

Per-pupil expenditure runs $13,067 according to the NCES F-33 School District Finance Survey, which aggregates every revenue and spending line reported under federal accounting standards. The funding mix is 47.2% local, 44.3% state, and 8.5% federal — a breakdown that matters because districts leaning heavily on local revenue are more exposed to property-tax swings, while higher federal shares typically track Title I concentration. Average teacher compensation clocks in at $53,793 per NCES F-33, a signal of the district's ability to recruit and retain staff against neighbouring districts. The district's equity score — 32/100, ranked #525 of 763 in Illinois against a state average of 38 — measures how evenly funding reaches schools within its boundaries.

a 376:1 student-counselor ratio, above the 250:1 ASCA recommendation, 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.

Unity Elementary School accounts for 44.0% of all CUSD 4 student enrollment

That concentration — well above the 8.4% national median for largest-entity share — means CUSD 4-wide averages can mask substantial variation outside the dominant entity. Grade band: other. 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.
