Summary
Pelham High School is a public grades 9–12 school serving about 508 students in the suburban town of Pelham, New Hampshire, near Nashua and the Massachusetts border. The school is part of the Pelham School District and offers a relatively small-school environment with a 10.3-to-1 student-teacher ratio. Pelham’s current statewide ranking—62nd of 89 New Hampshire high schools, or about the 30th percentile—has declined from the middle of the state rankings several years ago. Because rankings can vary from year to year, the longer-term decline is more meaningful than any single result.
Pelham’s academic results are mixed by subject. Reading is a clear strength: 61% of students were proficient, compared with 55% statewide, and results have remained near 60% in recent years. Mathematics is the school’s largest challenge, with just 19% proficiency compared with 44% statewide. Science performance is also below average at 23%, compared with 38% statewide, and both math and science results have declined over the past several years. Among nearby comprehensive schools, Pelham’s reading result is similar to Nashua High School South and higher than Nashua High School North, but its math and science results are generally toward the lower end of the local comparison group. By contrast, Windham High School and the specialized Academy for Science and Design Charter post substantially stronger results.
The school’s strongest outcomes are graduation and student persistence. Pelham’s 2024–2025 graduation rate was 95.2%, well above New Hampshire’s 87.0%, while its dropout rate was only 0.6%. These figures compare favorably with larger nearby schools, including Nashua South and Nashua North, and show that Pelham generally keeps students on track to complete high school. The main question for families is whether the school can maintain that strong support while improving college- and career-readiness skills in mathematics and science. Subgroup effectiveness, particularly for students receiving special education services, is another area worth asking about. Overall, Pelham offers a supportive, relatively small setting with strong graduation outcomes, but families should look closely at math, science, and special education supports.
