High Schools in Regional School Unit 21

Summary:

Regional School Unit 21 in Maine is home to one high school, Kennebunk High School, which has consistently ranked among the top high schools in the state. With a 5-star rating from SchoolDigger and a statewide ranking of 6th out of 119 schools for the 2024-2025 school year, Kennebunk High School stands out for its strong academic performance, high graduation rates, and personalized learning environment.

Kennebunk High School's proficiency rates in English Language Arts (78.47%), Mathematics (67.36%), and Science (58.13%) are significantly higher than the state averages, indicating a robust educational program. The school's four-year graduation rate of 87.8% is also a positive indicator of student success. However, the school's chronic absenteeism rate of 23.4% is higher than the state average, which may be an area for further investigation and targeted interventions.

While Regional School Unit 21 appears to have a high-performing high school, the relatively low percentage of students (8.91%) receiving free or reduced-price lunch at Kennebunk High School suggests that the school may serve a more affluent population, which could raise questions about equity and access to educational opportunities for students from lower-income backgrounds.
