District-Level NCES Analysis
Rsu 51/Msad 51 operates 4 public schools serving 2,153 students, placing it among the smallest districts in Maine. The school portfolio breaks down into 1 combined, 1 high, 1 middle, 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 Cumberland County.
Per-pupil expenditure runs $19,859 according to the NCES F-33 School District Finance Survey, in the upper half of 203 Maine districts by per-pupil spending. See how Maine compares in our national per-pupil spending analysis. The funding mix is 62.3% local, 34.5% state, and 3.3% 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 46/100, ranked #72 of 131 in Maine against a state average of 50, in line with the typical spread seen across the state for how evenly funding reaches its schools.
Academic infrastructure includes 1 of 4 schools offering Advanced Placement (11 AP courses district-wide), a 338.2:1 student-counselor ratio, well above the ASCA benchmark though still under the roughly 408:1 national average, and 12.9% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 90.9% White, 2.9% Hispanic or Latino, 1.0% Asian across the district's schools. Its most demographically mixed campus is Greely Middle School, with a diversity index of 19.5/100.
Its largest campus is Mabel I Wilson School, enrolling 730 students (33% of the district's total enrollment).
Mabel I Wilson School accounts for 32.7% of all Rsu 51/Msad 51 student enrollment
That dominant concentration means Rsu 51/Msad 51-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.
Rsu 51/Msad 51 student-counselor ratio is 338:1 — 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 Rsu 51/Msad 51 is typically wider than the Rsu 51/Msad 51-aggregate figure suggests.
Rsu 51/Msad 51 chronic absenteeism rate is 12.9% — low (typically associated with lower-than-average attendance disruption; districts in this range often have attendance interventions, robust transportation, or smaller catchments that reduce barriers)
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 Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
