District-Level NCES Analysis

RSU 51/MSAD 51 operates 4 public schools serving 2,153 students, placing it among the smaller districts in Maine. The school portfolio breaks down into 1 other, 1 high, 1 middle, 1 elementary schools, giving families a clear picture of grade-band coverage before they move, rent, or enrol. Aggregated across those campuses, enrollment totals 2,235 pupils using the NCES Common Core of Data (CCD) 2022-23 release, and the district is geographically located in Cumberland County County.

Per-pupil expenditure runs $20,613 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 62.3% local, 34.5% state, and 3.3% 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 $126,037 per NCES F-33, a signal of the district's ability to recruit and retain staff against neighbouring districts. The district's equity score — 46/100, ranked #72 of 131 in Maine against a state average of 50 — measures how evenly funding reaches schools within its boundaries.

Academic infrastructure includes 1 of 4 schools offering Advanced Placement (11 AP courses district-wide), a 338.2:1 student-counselor ratio, above the 250:1 ASCA recommendation, 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.

Mabel I Wilson School accounts for 32.7% of all RSU 51/MSAD 51 student enrollment

That concentration — well above the 8.4% national median for largest-entity share — means RSU 51/MSAD 51-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.

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.
