Summary:
Great Bay Charter School (H) is the only high school in the Great Bay Charter School district, serving grades 9–12 in Exeter, New Hampshire. The small school enrolls 94 students and has an 11.8-to-1 student–teacher ratio, offering a relatively close-knit setting. Because there is only one high school in the district, families cannot compare it with another local high school within the same district.
The school’s strongest results are related to graduation and student persistence. In 2024–2025, 91.3% of students graduated, higher than New Hampshire’s 87.0% rate, and the reported dropout rate was 0.0%, compared with 2.3% statewide. These results suggest that the school does a good job helping students remain enrolled and complete high school. Science is another relative strength: 33% of students were proficient on the 2025–2026 NH SAS science assessment, above the district’s 29% but below the state’s 38%. Science proficiency also improved from 25% the prior year.
Parents should also be aware of significant academic challenges, especially in reading. In 2025–2026, 35% of students were proficient in all-grades NH SAS reading, compared with 42% in the district and 55% statewide. The 11th-grade SAT reading proficiency rate was also 35%, 27 points below the state rate. Overall, the school ranked 76th out of 89 New Hampshire high schools, placing it near the 15th percentile and earning one star; its ranking has remained in the lower statewide range over the past three years. Reading performance fell sharply from 52% to 35% between 2024–2025 and 2025–2026, although results at this small school may change noticeably from year to year because a small number of students can affect percentages. Families may wish to ask about reading support, SAT preparation, and how the school is addressing this decline while maintaining its strong graduation outcomes.
