For parents, the most important point is that academic performance is well below New Hampshire averages in every tested subject. In 2025–2026, 19% of students were proficient in mathematics, compared with 44% statewide; 29% were proficient in reading, compared with 55% statewide; and 16% were proficient in science, compared with 38% statewide. Reading is the school’s relative strength, especially in Grade 6, where 41% were proficient, and Grade 8, where 40% were proficient. Mathematics is a broad concern across all tested grades, with proficiency ranging from 11% in Grade 7 to 24% in Grade 3. Science results were also low, at 13% in Grade 5 and 20% in Grade 8.

There are some encouraging patterns, but results vary considerably by grade. Reading performance improves noticeably after Grade 5, while Grade 5 is a particular concern because proficiency was only 19% in both reading and mathematics and 13% in science. Compared with the previous year, mathematics was unchanged, reading declined slightly, and science fell from 23% to 16%. The school ranked in the 3rd percentile statewide in 2025–2026, so parents may want to ask about plans for math improvement, the Grade 5 transition, science instruction, student growth, attendance, and academic supports. The relatively low student-teacher ratio could provide a useful foundation for targeted interventions.
