of 230 New Hampshire Elementary Schools

Better than 95% of New Hampshire elementary schools

Summary

Little Harbour School is a K–5 elementary school serving 325 students in Portsmouth’s Seacoast community and is part of the highly rated Portsmouth School District. The school ranks 12th among 230 New Hampshire elementary schools for 2025–2026, placing it in the 95th percentile, and has maintained a five-star rating for every reported year. Its student-teacher ratio is favorable at 9.5, and its long record of top statewide rankings suggests a consistently strong school rather than a one-year success.

Mathematics is Little Harbour School’s clearest strength. In 2025–2026, 84% of students were proficient in math, compared with 67% across the district and 44% statewide. Math proficiency has risen from 72% to 84% over four reported years. This was the strongest math result among Portsmouth’s three larger elementary schools, ahead of New Franklin School at 80% and Mary C. Dondero Elementary School at 79%. Reading was also strong at 78%, well above the 55% statewide rate, although it trailed New Franklin School at 85% and Rye Elementary School at 84%.

The main area to watch is science. Proficiency fell from 64% in 2022–2023 to 51% in 2025–2026, below the district’s 57% and well behind Mary C. Dondero Elementary School at 70%. Earlier-grade reading is another possible improvement focus: third- and fourth-grade results were 71% and 72%, compared with 91% in fifth grade. Even so, Little Harbour School remains one of the region’s strongest schools, ranking near peers such as New Franklin School and Mary C. Dondero Elementary School, while substantially outperforming schools such as Garrison School in math and reading.
