Summary

Timberlane Regional High School is a public school for grades 9–12 in Plaistow, New Hampshire, serving approximately 944 students in the suburban Timberlane Regional School District. The school is similar in size to Windham High School and somewhat smaller than several nearby high schools. It offers a mixed profile: graduation and student-retention results are strong, while academic performance—especially in mathematics—has become a significant concern.

Timberlane’s 2024–2025 graduation rate was 92.4%, above New Hampshire’s 87.0% average, and its dropout rate was just 0.7%. These results show that most students remain enrolled and graduate, although nearby schools such as Windham High School, Exeter High School, and Londonderry Senior High School have higher graduation rates. Reading is a relative strength: 56% of students reached proficiency in 2025–2026, roughly matching the state average. However, only 19% reached mathematics proficiency, compared with 44% statewide, and science proficiency was 28%, below the state’s 38%. Timberlane’s mathematics result trails Windham High School by 35 points and Exeter High School by 26 points.

The school’s overall ranking has declined from the upper-middle range earlier in the decade to 64th of 89 New Hampshire high schools, placing it in the lower third of the state. Its student-teacher ratio, at 11.3:1, is comparatively favorable, suggesting that class size alone does not explain the academic gaps. For families, the central takeaway is that Timberlane appears effective at supporting students through graduation but needs stronger academic results, particularly in mathematics and science. Its relatively steady reading performance and low dropout rate provide a useful foundation for improvement.
