District-Level NCES Analysis
Rsu 21 operates 6 public schools serving 2,425 students, placing it among the smallest districts in Maine. The school portfolio breaks down into 3 elementary, 1 high, 1 middle, 1 combined 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 York County.
Per-pupil expenditure runs $20,211 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 78.3% local, 18.5% state, and 3.2% 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 42/100, ranked #81 of 131 in Maine against a state average of 50, notably less even than the typical district in the state for how evenly funding reaches its schools.
Academic infrastructure includes 1 of 6 schools offering Advanced Placement (12 AP courses district-wide), a 242.2:1 student-counselor ratio, that meets the ASCA-recommended benchmark, and 27.8% chronic absenteeism from the 2021-22 Civil Rights Data Collection. Demographically, the student body averages 90.1% White, 4.0% Hispanic or Latino, 1.9% Asian across the district's schools. Its most demographically mixed campus is Sea Road School, with a diversity index of 23.6/100.
Its largest campus is Kennebunk High School, enrolling 683 students (30% of the district's total enrollment). Its smallest is Kennebunkport Consolidated Sch, at 199 students, a 3x enrollment spread across the district's campuses.
Kennebunk High School accounts for 28.2% of all Rsu 21 student enrollment
That dominant concentration means Rsu 21-wide averages can mask substantial variation outside the largest entity. Grade band: high. The share measures enrollment concentration only; it does not establish how the district allocates programs, capital, or staff. Enrollment-weighted aggregates give this entity more weight than any smaller peer, while an unweighted entity average treats every record equally.
Rsu 21 school enrollment varies 3.4× across entities
Rsu 21 school enrollment ranges from 199 students (lowest) to 683 students (highest), a spread of 484 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.
Rsu 21 student-counselor ratio is 242:1 — low (typically associated with meeting or exceeding the American School Counselor Association (ASCA) recommended 250:1 benchmark, which correlates with stronger college and career counseling capacity)
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 Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
Rsu 21 chronic absenteeism rate is 27.8% — 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 Rsu 21 is typically wider than the Rsu 21-aggregate figure suggests.
