Summary:
The Newmarket School District has one high school, serving grades 9–12, in the town of Newmarket, New Hampshire. With 274 students and a 9.8-to-1 student-teacher ratio, Newmarket Junior-Senior High School offers a relatively small-school setting. Since it is the district’s only high school, it represents the district’s entire high-school program rather than one option among several local schools.
Newmarket Junior-Senior High School has a strong overall profile. It received four stars and ranked 19th out of 89 New Hampshire schools in 2025–2026, placing it around the top fifth statewide. The school’s 94.7% graduation rate was 7.7 percentage points above the state average, and its reported dropout rate was 0%, compared with 2.3% statewide. Academic results were also above state averages in every reported subject: 66% of students were proficient in reading, 51% in science, and 46% in mathematics. Science was the school’s strongest area relative to the state, while SAT results were especially favorable in mathematics.
For families considering the area, the main strengths are the school’s consistently high ranking, strong graduation outcomes, and above-state performance in reading and science. The school has maintained a four-star rating across the three reported years, although its ranking moved from 16th to 19th most recently. Reading proficiency declined from 76% to 66% year over year but remained well above the state average. Mathematics is the clearest area to monitor because the school’s 46% proficiency rate was seven points below the district result, despite being slightly above the state average. Because the school is small, percentages may change noticeably from year to year, so families may want to review longer-term trends and program details as well.
