Summary:
Plaistow, New Hampshire, has three public schools serving about 2,101 students from prekindergarten through grade 12 within the Timberlane Regional School District, a suburban-area district ranked around the 39th percentile statewide.
The strongest overall performer is Timberlane Regional Middle School, ranked in the 48th statewide percentile and showing fairly balanced results in math and reading. Its 7th-grade math proficiency is 50%, above the state’s 44%, while 7th-grade reading reaches 61%, above the state’s 57%. The main concern is science, with 28% proficiency compared with 38% statewide. Pollard Elementary School has shown encouraging improvement, especially in math, which rose nine percentage points to 45% in 2025–26. Third-grade math is a standout at 57%, above both district and state results. However, reading remains below state levels in every tested grade, and science also trails the state.
Timberlane Regional High School has the district’s strongest completion outcomes, with a 92.4% graduation rate and a 0.7% dropout rate, both better than New Hampshire averages. Its academic results are more concerning: the school ranks in the 28th statewide percentile, math proficiency is 19%, and science proficiency is 28%. Its ranking has declined from the 46th percentile in 2023–24, making high school math and science important areas to watch. Across Plaistow’s schools, reading is generally stronger than math and science, while science is a consistent weakness. Student-teacher ratios are relatively low, ranging from 10.1 to 11.3 students per teacher, and reported economic-need rates are comparatively modest. Overall, the middle school offers the most stable profile, Pollard is improving but needs stronger reading results, and the high school combines strong graduation outcomes with weaker academic proficiency.
