Summary:
Byfield, Massachusetts has two public schools — one middle school serving grades 7–8 and one high school serving grades 9–12 — both part of the Triton district and sharing a single campus at 112 Elm Street. Together, Triton Regional Middle School (297 students) and Triton Regional High School (538 students) enroll 835 students. The district as a whole ranks 111 of 351 in Massachusetts, at the 68th percentile with 3 stars.
Triton Regional Middle School is the steadier performer. It has held between the 67th and 69th percentile with 3 stars for three straight years, and it keeps class sizes comparatively small with a student-teacher ratio of 9.6. Its standout result is 8th grade Science: 53.57% proficient, well above the state's 38.93% and the largest positive gap versus the state in this data. 8th grade Civics also improved from 38.10% to 44.44% year over year, moving from slightly below state to above it. Most grade-level results sit at or above district and above state, though its All Grades averages trail the district in ELA, Math, and Science — likely because the district average spans other schools and grades.
Triton Regional High School tells a more mixed story. Its graduation rate of 95.9% and dropout rate of 2.7% both beat the district's 92.9% and 3.2%, and its students scored above the district average in every reported test. However, in 2025–2026 the school fell below the state in all four reported areas, and its ranking slipped to 181 of 353 — the 49th percentile with 2 stars — down from the 56th percentile the prior year. 10th grade ELA, Math, and Science all declined year over year. The high school also spends more per student, $20,159 versus $18,413 in 2020–2021. Free/reduced lunch data is not reported for either school, so economic context cannot be compared here.
