Summary:
The Winnisquam Regional High School is the only high school in the Winnisquam Regional School District. Located in Tilton, New Hampshire, it serves about 357 students in grades 9–12. The school is in a relatively small community, where enrollment can make year-to-year results more variable than at larger schools. Its student-teacher ratio is 16.2 to 1, and about 30.5% of students qualify for free or reduced-price lunch.
The school’s strongest results are its graduation and student-retention outcomes. The 2024–2025 graduation rate was 90.2%, above New Hampshire’s 87.0% rate, while the reported dropout rate was 0.0%, compared with 2.3% statewide. Reading is also a consistent strength: 55% of students were proficient on the 2025–2026 all-grades NH SAS assessment, matching the state and exceeding the district’s 45%. Science improved considerably, rising from 28% proficiency in 2024–2025 to 41% in 2025–2026. The latest science result was above both the district’s 36% and the state’s 38%.
Parents should view mathematics as the school’s most important academic concern. In 2024–2025, just 10% of students were proficient in math, compared with 41% in the district and 42% statewide; a newer math result was not provided, so it is unclear whether performance has improved. Eleventh-grade SAT reading was 55% proficient, equal to the district but seven points below the state. Overall, the school’s ranking improved substantially, moving from the 9th to the 57th percentile between 2023–2024 and 2025–2026, with its rating increasing from one to three stars. The combination of solid graduation results, stable reading, and improving science is encouraging, but families should seek current math data and ask how the school is addressing that subject’s earlier weakness.
