Summary:
ZIP code 03443 has one listed school, Chesterfield Central School, a small public school serving kindergarten through eighth grade in the Chesterfield area. The school enrolls 253 students and has a favorable 10.9-to-1 student-teacher ratio. Because it is the only school in the ZIP code, families are choosing among grade-level programs within one school rather than comparing several local campuses.
Chesterfield Central School performs above New Hampshire averages overall. In 2025–2026, 53% of students were proficient in mathematics, compared with 44% statewide; 62% were proficient in reading, compared with 55%; and 47% were proficient in science, compared with 38%. Mathematics improved by nine percentage points and reading by eight points from the prior year, while science remained nearly steady. Reading is the school’s strongest overall subject. The school also offers a relatively small-school setting, which may support closer teacher attention, although results in individual grades can change noticeably from year to year when cohorts are small.
Performance varies considerably by grade. Seventh grade was a major strength, with 88% proficiency in both mathematics and reading. Eighth grade also performed well, particularly in mathematics, where proficiency was 63%, and science, where it was 54%. The clearest concern is fifth-grade mathematics, with 19% proficiency compared with 43% statewide. Fourth-grade mathematics and reading, along with sixth-grade reading, were also below state averages and may deserve additional attention. The school’s ranking improved from the 38th percentile in 2024–2025 to the 47th percentile in 2025–2026, though it remains below its 2023–2024 standing. The Chesterfield School District ranks 60th of 166 districts, in the 64th percentile.
