District-Level NCES Analysis
Rsu 40/Msad 40 operates 7 public schools serving 1,800 students, placing it among the smallest districts in Maine. The school portfolio breaks down into 3 combined, 2 elementary, 1 high, 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 Knox County.
Per-pupil expenditure runs $16,287 according to the NCES F-33 School District Finance Survey, in the lower half of 203 Maine districts by per-pupil spending. See how Maine compares in our national per-pupil spending analysis. The funding mix is 52.7% local, 44.8% state, and 2.6% 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 #73 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 7 schools offering Advanced Placement (12 AP courses district-wide), a 260.1:1 student-counselor ratio, somewhat above the 250:1 ASCA recommendation, and 35.0% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 92.5% White, 2.9% Hispanic or Latino, 0.4% African American across the district's schools. Its most demographically mixed campus is Warren Community School, with a diversity index of 18.7/100.
Its largest campus is Medomak Valley High School, enrolling 561 students (32% of the district's total enrollment). Its smallest is Friendship Village School, at 62 students, a 9x enrollment spread across the district's campuses.
Medomak Valley High School accounts for 31.2% of all Rsu 40/Msad 40 student enrollment
That dominant concentration means Rsu 40/Msad 40-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.
Rsu 40/Msad 40 school enrollment varies 9.0× across entities
Rsu 40/Msad 40 school enrollment ranges from 62 students (lowest) to 561 students (highest), a spread of 499 students. That spread reflects typical mixed-portfolio variation between specialty programs and large neighbourhood schools. Per-school staffing ratios, programme availability, and capital-renovation cycles often diverge inside the same district based on enrollment shape.
Rsu 40/Msad 40 student-counselor ratio is 260:1 — 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 40/Msad 40 is typically wider than the Rsu 40/Msad 40-aggregate figure suggests.
Rsu 40/Msad 40 chronic absenteeism rate is 35.0% — high (typically associated with higher-than-average disruption; recent CRDC data showed elevated rates persisting after pandemic-era schooling changes)
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
