RSU 21 operates 6 public schools serving 2,425 students, placing it among the smaller districts in Maine. The school portfolio breaks down into 3 elementary, 1 high, 1 middle, 1 other schools, giving families a clear picture of grade-band coverage before they move, rent, or enrol. Aggregated across those campuses, enrollment totals 2,262 pupils using the NCES Common Core of Data (CCD) 2022-23 release, and the district is geographically located in York County County.
Per-pupil expenditure runs $21,034 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 78.3% local, 18.5% state, and 3.2% 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 $119,765 per NCES F-33, a signal of the district's ability to recruit and retain staff against neighbouring districts. The district's equity score — 43/100, ranked #78 of 131 in Maine against a state average of 50 — measures how evenly funding reaches schools within its boundaries.
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.
Kennebunk High School accounts for 30.2% of all RSU 21 student enrollment
That concentration — well above the 8.4% national median for largest-entity share — means RSU 21-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 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.
