In 2025–2026, SchoolDigger ranks it 148th of 478 Massachusetts middle schools — the 69th percentile, with 3 stars — stronger than the Lunenburg district overall (166th of 351, 53rd percentile). The school has long been upper-middle in the state, with percentile ranks of 74, 70, 71, 72, 71, 75, and 69 in recent years, so this year is a modest one-year dip from 4 stars and the 75th percentile to 3 stars and the 69th.
Academically, the school scores above the Massachusetts average in every tested subject: ELA 43.94% proficient vs. 40.03%, math 45.11% vs. 41.11%, science 47.12% vs. 40.98%, and civics 53.33% vs. 39.77%. Civics and science are the standout strengths. Within its own district, math (45.11%) is the one subject below the district average (47.04%), with 6th- and 7th-grade math strong and 8th-grade math slightly below the state. Among nearby schools, Lunenburg sits mid-to-upper: it trails The Bromfield Middle School (93rd percentile), Luther Burbank Middle School (86th), and Groton Dunstable Regional Middle (79th) in ELA, math, and science, but edges out Luther Burbank in civics and roughly matches Ayer Shirley Regional Middle School in science while doing better in ELA and math.
Low-income students are a bright spot, consistently earning 4 stars at the 73rd–78th percentile. Special education students, however, fell to 3 stars and the 54th percentile in 2025–2026 after two stronger years. The student–teacher ratio rose to 15.2, higher than most nearby schools, and per-student spending was $15,285 as of 2020–2021, mid-range locally. Overall: solid and above state, with a recent dip and mixed math results worth monitoring.
