Summary:
ZIP code 03048, which covers the small community of Mason, New Hampshire, has one public school: Mason Elementary School, serving students from pre-kindergarten through fifth grade in the Mason School District. With 106 students enrolled, the area does not offer a middle school, high school, or alternative school within the ZIP code, so families will need to look outside the ZIP code for later grades.
Mason Elementary School is a notably high-performing school. It ranked third out of 230 New Hampshire schools for 2025–2026, placing it in the 99th percentile with a five-star rating. The school’s ranking has improved from ninth two years earlier. Academic results were also well above state averages: 83% of students were proficient in mathematics, 86% in reading, and 84% in science, compared with statewide rates of 44%, 55%, and 38%. The school reported a favorable student-teacher ratio of 12.3 to 1, which may support a more personal learning environment, although this figure is not the same as average class size.
Fifth-grade results were especially strong, with 95% proficiency in mathematics and 100% in reading; fifth-grade science proficiency was 84%. Fourth-grade mathematics and reading proficiency were both 79%, showing solid performance but a noticeable difference from fifth grade that may reflect normal year-to-year variation in small cohorts. Reading improved by two percentage points and mathematics by one point from the prior year. Science declined four points, from 88% to 84%, making it the main trend to monitor, though the result remains excellent compared with the state. Overall, the available data portrays a small school with consistently strong academics and improving statewide standing.
