District-Level NCES Analysis
Affton 101 operates 4 public schools serving 2,608 students, placing it among the smallest districts in Missouri. The school portfolio breaks down into 1 high, 1 combined, 1 elementary, 1 middle 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 St. Louis County.
Per-pupil expenditure runs $11,725 according to the NCES F-33 School District Finance Survey, in the lower half of 549 Missouri districts by per-pupil spending. See how Missouri compares in our national per-pupil spending analysis. The funding mix is 77.7% local, 12.6% state, and 9.7% 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 29/100, ranked #361 of 432 in Missouri against a state average of 50, notably less even than the typical district in the state for how evenly funding reaches its schools.

That dominant concentration means Affton 101-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.
Affton 101 student-counselor ratio is 280:1 — 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 Affton 101 is typically wider than the Affton 101-aggregate figure suggests.
Affton 101 chronic absenteeism rate is 26.6% — 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 Affton 101 is typically wider than the Affton 101-aggregate figure suggests.
