Summary:
ZIP code 03839 contains one listed school, Gonic School, an elementary school serving kindergarten through fifth grade in the Rochester area. The school enrolls 211 students and has a student–teacher ratio of 10.5 to 1. It is part of the Rochester School District. Because there is only one school in the ZIP code, families are primarily comparing Gonic’s performance with district and New Hampshire results rather than choosing among several local schools.
Gonic’s strongest area is reading, where 53% of students were proficient overall in 2025–2026, just below the statewide rate of 55% but 10 percentage points above the district. Fifth-grade reading was especially strong at 75%, exceeding the state by 17 points. Third-grade reading was also above the state, at 55%. Mathematics results were 41% overall, 14 points above the district and only 3 points below the state. Fifth-grade math reached 44%, slightly above the statewide result. Science was weaker at 31%, although it still exceeded the district by 5 points. Overall, the school performs considerably better than its district in all three subjects.
Performance varies significantly by grade. Fourth grade is the clearest area for improvement: reading proficiency was 30%, compared with 52% statewide, while math was 36%, 16 points below the state. Mathematics also declined from 48% to 41% year over year, while reading improved slightly and science dipped modestly. Even so, Gonic’s longer-term ranking improved from the 21st percentile in 2023–2024 to the 38th percentile in 2025–2026, despite a decline from the previous year. For parents, the main takeaway is that Gonic offers stronger results than the surrounding district, particularly in fifth-grade reading and overall reading, while fourth-grade achievement, math consistency, and science are the most important areas to monitor.
