Summary:
ZIP code 03576 has one high school: Colebrook Academy and Elementary School, serving grades 9–12 in Colebrook, New Hampshire. The school is part of the Colebrook School District and has 99 students, a low 8.3-to-1 student–teacher ratio, and a relatively small-school setting. About 36% of students qualify for free or reduced-price meals. Since there are no other high schools in the ZIP code, families are choosing among the school’s strengths and areas for improvement rather than comparing multiple local campuses.
The school’s overall trajectory is encouraging. Its statewide ranking improved from 65th of 85 schools in 2022–2023 to 23rd of 86 in 2024–2025, moving from approximately the 24th to the 73rd percentile and from a one-star to a four-star rating. Completion outcomes are also strong: the 2024–2025 graduation rate was 92.3%, above New Hampshire’s 87.0%, while the reported dropout rate was 0.0%, compared with 2.3% statewide. Science is a particular standout, with 74% of students proficient in 2024–2025, compared with 44% in the district and 38% statewide. Reading was also above the state in that year, at 59% versus 55%.
Academic results are mixed, so parents may want to look beyond the strong graduation and ranking numbers. Mathematics proficiency was 33%, below the state’s 42% but above the district’s 27%. More recent reading results were weaker: 37% on the 2025–2026 NH SAS and 37% on the Grade 11 SAT reading measure, compared with 55% statewide for NH SAS reading and 62% statewide for SAT reading. These newer results may reflect differences in student cohorts or testing conditions, but they warrant monitoring. Because enrollment is small, a few students can significantly affect annual percentages, making multi-year trends especially important.
