Summary:
The 03275 area has five schools serving grades K–12, with about 2,030 students across three districts or charter organizations: Pembroke School District, Allenstown School District, and Strong Foundations Charter School. The group includes three elementary schools, one middle school, and one high school, with academic results generally strongest in elementary and middle grades.
Pembroke Hill School is the strongest overall performer, ranking in the 66th percentile statewide. Its mathematics and reading proficiency rates are both 57%, with mathematics well above the state average. Three Rivers School is the leading middle school, ranking in the 60th percentile and posting the area’s strongest reading result at 61%; its science performance is also above the state average. Both schools have favorable student-teacher ratios near 10 students per teacher and show stable or improving results. Strong Foundations Charter School has a lower overall ranking, but it stands out for science, where 49% of students are proficient compared with 38% statewide. It also made the largest recent gains, especially an 18-point increase in science.
Pembroke Academy requires the most attention. It ranks in the 17th percentile, and its 2025–2026 proficiency rates were 15% in mathematics, 53% in reading, and 20% in science. All three subjects declined from the prior year, while its graduation rate of 82.5% remains below the state average, although its dropout rate is better than the state’s. Allenstown Community School also trails the state in all three subjects and has the highest free/reduced-price lunch participation in the area, an important context when comparing results. Overall, reading is the strongest subject locally, mathematics is the most common weakness, and families should consider both schoolwide rankings and grade-level results.
