Summary:
Cornish, New Hampshire, has one public school: Cornish Elementary School, a small PK–8 school serving about 137 students through the Cornish School District. Because it is the only public school in the community and serves nearly all elementary and middle-grade students, there are no local school-to-school comparisons. Families should view it as a small, broad-grade-span school where results may vary noticeably from year to year because each grade has a relatively small number of students.
Families may value the school’s 10.6-to-1 student-teacher ratio, which can support a more personal learning environment, although this figure does not necessarily equal average class size. In 2025–2026, mathematics proficiency was 40%, compared with 44% statewide, while reading was 43%, compared with 55% statewide, and science was 33%, compared with 38%. Mathematics is the school’s relative strength: third- and fourth-grade results were above the state averages, and sixth grade was slightly above the state as well. However, fifth-grade mathematics was 27% and seventh-grade mathematics was 23%, making those grades important areas for families to monitor.
Reading was below the state average in every tested grade, with the largest gaps in fourth and seventh grades. Science also declined from 43% proficiency in 2024–2025 to 33% in 2025–2026, so parents may want to ask how literacy and science instruction, intervention, and student support are being strengthened. The school’s ranking fell from the 68th percentile in 2023–2024 to the 30th percentile in 2025–2026, though rankings can fluctuate substantially in a small school. Overall, the school offers a close-knit setting and some strong elementary mathematics results, but reading across grades and later-grade mathematics deserve particular attention.
