Summary
Granby Junior Senior High School is a small public school in Granby, MA, serving roughly 290 students in grades 7 through 12 as the high school for the Granby district. In 2025–2026 it ranked 242nd of 353 Massachusetts schools (31st percentile, 2 stars), a slight improvement from 259th of 349 in 2024–2025, but still below the state median.
The clearest strength is completion. Granby Junior Senior High School reported a 100.0% graduation rate and 0.0% dropout rate in 2024–2025 — the best of any nearby school, ahead of Chicopee Comprehensive High School (93.7%), South Hadley High (93.2%), and Belchertown High (89.7%), and far ahead of Holyoke High (81.3%). Test proficiency is the weaker area. All-grade 2025–2026 rates were 29.46% in ELA, 26.55% in math, and 32.20% in science, all below state averages. At 10th grade, ELA (39.02%) and math (29.27%) were nearly tied with Chicopee Comprehensive and well above Holyoke, but below Ludlow Senior High, Hopkins Academy, Pioneer Valley Performing Arts Charter Public School, Hampden Charter School of Science, South Hadley, and Belchertown. Biology (20.59%) and 8th-grade ELA (26.32%), math (22.41%), and civics (22.03%) trail the state substantially.
Because Granby covers grades 7–12, its "all grades" scores blend 7th, 8th, and 10th grade results, making 10th grade the fairest comparison with 9–12 high schools. Some scores did rise from 2024–2025 to 2025–2026, including all-grade math (19.44% to 26.55%), and resources look mid-range: $17,069 per student in 2020–2021 and an 11.0 student-teacher ratio in 2024–2025. The bottom line: students stay and graduate at an exceptional rate, while academic proficiency remains below state and most neighbors.
