Summary:
The Winnacunnet Cooperative School District has one high school, Winnacunnet High School, serving grades 9–12 in Hampton, New Hampshire, with 993 students. Because it is the district’s only high school, its performance represents the district as a whole. The school is relatively large, has a reported student-teacher ratio of 10.1 to 1, and currently holds a four-star rating.
Winnacunnet High School is performing better than New Hampshire overall in several important academic areas. In 2025–2026, 68% of students were proficient in reading, compared with 55% statewide, while science proficiency was 47%, compared with 38% statewide. Mathematics proficiency rose substantially from 33% to 44% in one year, matching the state average. Eleventh-grade SAT results were particularly strong: mathematics proficiency was 44%, compared with 30% statewide, and reading proficiency was 68%, compared with 62%. These results point to reading and science as clear strengths, with mathematics showing meaningful improvement but still remaining an area to watch.
The school’s ranking also improved, moving from 30th of 86 schools in 2024–2025 to 20th of 89 in 2025–2026, rising from the 65th to the 78th percentile. Student retention is another major strength: the dropout rate was just 0.3%, well below New Hampshire’s 2.3%. The main concern is the four-year graduation rate, which was 84.6%, compared with 87.0% statewide. This combination of strong test results, very low dropout rates, and a somewhat lower graduation rate suggests that the school may need to focus on helping more students complete requirements on time. Overall, families can view Winnacunnet High School as a strong, improving school, with especially positive results in reading, science, SAT performance, and student persistence.
