Summary:
The Oyster River Coop School District has three elementary-level schools serving students in PK through grade 4: two K–4 schools and one small PK–K preschool program, with 687 students across the district’s elementary programs.
The two main elementary schools, Mast Way School and Moharimet School, are both high-performing schools and have five-star ratings. Moharimet is the current standout, ranking 5th out of 230 New Hampshire schools in 2025–2026, with 84% mathematics proficiency and 83% reading proficiency. It also has the strongest third-grade results, with 90% proficiency in both subjects, and has improved substantially in recent years. Mast Way ranks 15th statewide and offers similarly strong results, including 75% mathematics and 82% reading proficiency. It is especially strong in fourth grade, where 84% of students are proficient in math and 86% in reading—the highest individual subject-grade result in the available data. Mast Way is also the larger school, enrolling 348 students compared with Moharimet’s 309.
For families comparing the two K–4 schools, Moharimet stands out for current ranking, third-grade performance, recent academic growth, and its slightly lower student-teacher ratio of 12.3, while Mast Way is notable for consistency over time and excellent fourth-grade outcomes. Both schools perform far above state averages in math and reading. The Oyster River Preschool Education Program is much smaller, serving 30 students in PK–K, and does not have comparable state assessment results. Its early-childhood focus means it is best considered separately from the two K–4 schools.
