Summary:
ZIP code 03857 has one elementary school, Newmarket Elementary School, serving Pre-K through Grade 5 in the Newmarket community. The school enrolls 474 students and reports an 11.7-to-1 student-teacher ratio. Because it is the only elementary school in the ZIP code, parents will not find a local school-to-school comparison; the most useful benchmarks are the school’s performance over time, the Newmarket School District, and New Hampshire statewide results.
Reading is Newmarket Elementary’s strongest area. In 2025–2026, 63% of students were proficient in reading, compared with 55% statewide. Results were above the state in every tested grade, including a particularly strong 68% proficiency rate in fifth grade. Mathematics performance was also better than the state overall, with 50% proficiency compared with 44% statewide, although results declined from 53% in third grade to 45% in fifth grade. The school’s scores were slightly below district averages in both reading and mathematics, but the district itself ranked 51st of 166 districts, placing it in the 69th percentile and earning four stars.
Science is the clearest area for improvement. Only 39% of students were proficient in 2025–2026, just above the statewide rate of 38% and 9 points below the district. Science also dropped sharply from 54% the previous year, while mathematics fell 5 points and reading remained steady at 63%. The school’s overall ranking declined from 43rd of 234 schools in 2023–2024 to 86th of 230 in 2025–2026, though it still ranked above the midpoint statewide. For parents, the key takeaway is that Newmarket Elementary offers stable, above-state reading performance and competitive mathematics results, while science and upper-grade mathematics merit the closest attention.
