Summary

Great Bay Charter School (H) is a small public charter high school in Exeter, NH, serving 94 students in grades 9–12 in a close-knit setting near several larger regional and charter schools. Its 11.8-to-1 student-teacher ratio is competitive with nearby schools, although its small enrollment means that a few students can significantly affect yearly percentages and rankings.

The school’s academic results are its main challenge. Great Bay ranked 76th of 89 New Hampshire high schools in 2025–26, placing it in the 15th percentile and earning a one-star rating. Reading proficiency was 35%, compared with 55% statewide and 70% at nearby Exeter High School. Great Bay’s science proficiency was 33%, only five points below the state average and higher than results at Epping High School, Timberlane Regional High School, and Sanborn Regional High School. Mathematics remains the biggest concern: the latest reported result was 0% proficiency in 2023–24, and no current mathematics result was provided. Reading also declined from 52% to 35% between 2024–25 and 2025–26.

Great Bay’s completion outcomes are notably stronger than its test scores. The 2024–25 graduation rate was 91.3%, above New Hampshire’s 87.0% and higher than Winnacunnet High School and Virtual Learning Academy (H). Its dropout rate was 0%, an encouraging sign that students are staying enrolled. Compared with nearby Virtual Learning Academy (H), Great Bay has much lower academic proficiency but a substantially higher graduation rate. Parents may want to ask about current math data, reading interventions, student growth, and how the school is building on its strong recent improvement in graduation and retention.

Outstanding school. Teachers and staff as a whole are amazing and clearly love their profession. They put the students first, which is a refreshing change from what we experienced from the SAU16 middle school. We had concerns initially about a charter school as our child ranks on the upper end educationally and intellectually. We weren't sure if he'd be challenged enough but we have found the project based curriculum is so much more engaging then the standard core curriculum that we couldn't be happier with our decision to switch from public schools. The smaller size of the school makes for a much more community feel and great interaction with the student body and staff overall. Can't recommend this school enough! Close Quote

My two sons attend GBeCS and they love it! The small class size allows teachers to be able to reach students with varying learning styles. Every adult in the building is caring, embracing each students individuality which in turn teaches students respect. Close Quote
