Summary:
Seacoast Charter School is the only school in this list, serving students from Pre-K through Grade 8 in Dover, New Hampshire, with 287 students and a student–teacher ratio of 13.6 to 1. For parents considering the school, its results show a mixed but improving academic picture: science is a major strength, reading is slightly above the New Hampshire average, and mathematics remains the main area needing attention.
In 2025–2026, 55% of students were proficient in science, compared with 38% statewide, including an especially strong Grade 8 result of 66%. Reading proficiency was 57%, slightly above the state’s 55%; Grade 8 reading was particularly strong at 69%, while Grades 4–6 also exceeded state rates. Mathematics proficiency was 38%, below the statewide 44%. The largest concern was Grade 3 mathematics, where 28% of students were proficient compared with 54% statewide. Grade 3 reading was also below the state, at 39% versus 51%. These results suggest that families may want to ask about early-grade reading and math support, while also noting the school’s strong upper-grade performance.
The school improved across all three subjects from the prior year: mathematics rose seven percentage points, reading increased four points, and science gained five points. Its statewide ranking also improved from 161st of 224 schools in 2024–2025 to 132nd of 230 in 2025–2026, returning to the 43rd percentile and a two-star rating. The small enrollment and relatively low student–teacher ratio may appeal to families seeking a compact school setting, although the available data do not show class sizes or subgroup results. Overall, the most important strengths are science, Grade 8 achievement, and recent broad-based improvement; the clearest priority is strengthening elementary mathematics and reading.
