District-Level NCES Analysis
Canon-Mcmillan Sd operates 9 public schools serving 5,347 students, placing it among the smaller districts in Pennsylvania. The school portfolio breaks down into 7 elementary, 1 high, 1 middle schools, a compact enough portfolio that families can compare every campus directly before they move, rent, or enrol. These enrollment and school figures come from the NCES Common Core of Data (CCD) 2024-25 release, and the district is based in Washington County.
Per-pupil expenditure runs $13,471 according to the NCES F-33 School District Finance Survey, among the bottom 68 of 671 Pennsylvania districts by per-pupil spending. See how Pennsylvania compares in our national per-pupil spending analysis. The funding mix is 69.3% local, 25.5% state, and 5.2% 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 13/100, ranked #633 of 648 in Pennsylvania against a state average of 49, notably less even than the typical district in the state for how evenly funding reaches its schools.
Academic infrastructure includes 1 of 9 schools offering Advanced Placement (20 AP courses district-wide), a 382.8:1 student-counselor ratio, well above the ASCA benchmark though still under the roughly 408:1 national average, and 8.3% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 82.9% White, 4.0% African American, 3.6% Hispanic or Latino across the district's schools. Its most demographically mixed campus is South Central El, with a diversity index of 41.1/100.
Its largest campus is Canon-Mcmillan Shs, enrolling 1,660 students (31% of the district's total enrollment). Its smallest is Hills-Hendersonville El Sch, at 267 students, a 6x enrollment spread across the district's campuses.
Canon-Mcmillan Shs accounts for 30.8% of all Canon-Mcmillan Sd student enrollment
That dominant concentration means Canon-Mcmillan Sd-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.
Canon-Mcmillan Sd school enrollment varies 6.2× across entities
Canon-Mcmillan Sd school enrollment ranges from 267 students (lowest) to 1,660 students (highest), a spread of 1,393 students. That relatively narrow ratio reflects an unusually homogeneous campus portfolio, most districts have a wider mix of school sizes. Per-school staffing ratios, programme availability, and capital-renovation cycles often diverge inside the same district based on enrollment shape.
Canon-Mcmillan Sd student-counselor ratio is 383:1 — 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.
Canon-Mcmillan Sd chronic absenteeism rate is 8.3% — well below typical (typically associated with unusually small scale or exceptionally high per-unit investment)
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 Values this far below typical often correlate with unusually small scale or population characteristics rather than higher resource budgets per se — worth checking whether the underlying denominator is itself an outlier.
