Elementary Schools in Regional School Unit 10

Summary:

Regional School Unit 10 in Maine is home to three elementary schools: Hartford-Sumner Elementary School, Rumford Elementary, and Meroby Elementary School. These schools serve students from pre-kindergarten through 5th grade in the surrounding communities.

Among the three schools, Hartford-Sumner Elementary School stands out as the highest-performing, with 65.31% of students proficient or better in English Language Arts and 48.3% proficient or better in Mathematics on state assessments. This is significantly higher than the district and state averages. Hartford-Sumner also has a higher statewide ranking, placing 180th out of 289 Maine elementary schools, compared to Rumford Elementary (250th) and Meroby Elementary (282nd). Additionally, Hartford-Sumner has a higher rating of 2 stars out of 5 from SchoolDigger, while the other two schools are rated 1 star or less.

However, all three schools in Regional School Unit 10 face challenges, including high chronic absenteeism rates, ranging from 23.4% of students chronically absent in the 2023-2024 school year. The schools also have varying rates of free and reduced-price lunch recipients, with Rumford Elementary having the highest at 81.33%, followed by Meroby Elementary at 69.29%, and Hartford-Sumner at 50.17%. While the student-teacher ratios are relatively low, ranging from 9.8 at Meroby Elementary to 11.2 at Hartford-Sumner, the district as a whole needs to address the significant performance gaps and declining rankings observed in some of the schools.
