Summary:
ZIP code 03446 has one public high school, Monadnock Regional High School in Swanzey, New Hampshire, serving grades 9–12 and about 448 students through the Monadnock Regional School District. The school has a relatively low student-teacher ratio of 12.7 to 1, and about 25% of students qualify for free or reduced-price lunch. Since there is only one high school in the ZIP code, families are evaluating this school on its own rather than comparing several local high schools.
Monadnock Regional High School performs better than its district in several recent academic measures, but it remains below New Hampshire averages. In 2025–2026, reading proficiency was 47%, compared with 40% in the district, while science proficiency was 26%, compared with 20% districtwide. Mathematics was the clearest weakness: only 17% of students were proficient, compared with 33% in the district and 44% statewide. The same 17% result appeared in 11th-grade SAT mathematics. Reading was a relative strength, although proficiency fell from 57% the previous year to 47%, making the recent decline worth watching. Science remained steady at 26%.
For families focused on completion and student support, the reported 2024–2025 graduation rate was 85.7%, just below the statewide rate of 87%. The dropout rate, however, was 8.1%, substantially higher than New Hampshire’s 2.3% rate and the school’s most serious concern. The school ranked 75th out of 89 comparison schools in 2025–2026 and received a one-star rating, although this was an improvement over its 2023–2024 ranking. Overall, the school offers a small-school setting and performs relatively well against its district in reading and science, but parents should ask about mathematics interventions, attendance and dropout prevention, credit recovery, and the reasons behind the recent reading decline.
