Summary:
Windham, New Hampshire, has one elementary-level school in the Windham Academy Public Charter School district: Windham Academy Public Charter School, a K–8 public charter school serving 410 students at 1 Industrial Drive. The school reports a 15.7:1 student–teacher ratio and a very low free- or reduced-price lunch eligibility rate of 3.17%, or approximately 13 students, which provides useful context when considering its achievement results.
Overall, Windham Academy Public Charter School performs above New Hampshire averages in every reported subject. In 2025–2026, proficiency was 63% in reading, compared with 55% statewide; 48% in mathematics, compared with 44%; and 40% in science, compared with 38%. Reading is the school’s clearest strength, with results above the state in every tested grade. Grade 7 reading was especially strong: 80% of students were proficient, 23 points above the state average. Families should also note that mathematics performance varies considerably by grade. Grade 3 was excellent at 70%, but Grade 5 fell to 32%, 11 points below the state, before improving in Grades 6 and 7.
The main area to watch is science. Although the school was slightly above the state overall, science proficiency declined from 50% to 40% between 2024–2025 and 2025–2026. Reading also dipped three points, while mathematics remained nearly unchanged. The school’s ranking history declined from the 75th percentile in 2023–2024 to the 62nd percentile in 2025–2026, though a separate current summary lists it at 57th of 166 schools, likely reflecting a different comparison group. For parents, the overall picture is favorable: this small K–8 school has particularly strong literacy results, generally above-average achievement, and focused improvement needs in Grade 5 mathematics and science.
