Summary:
ZIP code 03865 has one public high school, Timberlane Regional High School in Plaistow, serving grades 9–12 with about 944 students; the school is part of the Timberlane Regional School District.
Timberlane Regional High School has several important strengths for families to consider. Its 92.4% graduation rate is higher than New Hampshire’s 87.0% rate, while its 0.7% dropout rate is well below the statewide 2.3% rate. These figures suggest that most students remain enrolled and complete high school successfully. Reading is also a relative strength: 56% of students reached proficiency, slightly above the state’s 55% and four points above the district result. The school’s 11.3-to-1 student-teacher ratio may also support more individualized attention, although it does not necessarily represent average class size.
The main concern is academic performance in mathematics and science. Only 19% of students were proficient in math, compared with 44% statewide and 42% in the district, while science proficiency was 28%, below both the district’s 32% and the state’s 38%. Eleventh-grade SAT results show a similar pattern, with 19% meeting the math benchmark and 56% meeting the reading benchmark, both below statewide results. Performance declined from the prior year in math, reading, and science, and the school’s ranking fell from the 46th percentile to the 28th percentile over three years. For parents, the overall picture is mixed: strong graduation and persistence outcomes, but a clear need for improved math and science achievement while maintaining reading performance.
