Summary
Arthur M Longsjo Middle School is a grades 6–8 school in Fitchburg, MA, serving 614 students as part of the Fitchburg district, which ranks 325th of 351 districts statewide. In 2025–2026, Arthur M Longsjo Middle School ranked 423rd of 478 middle schools — the 12th percentile, with 1 star — its lowest percentile in the displayed history. Over the past decade it has never climbed above the 24th percentile and has earned 1 star every year, so this is a long-standing pattern rather than a one-year dip.
Proficiency is well below both district and state levels. In 2025–2026, 15.99% of students met standards in English language arts, 12.72% in math, 19.88% in science, and 15.63% in civics, compared with 21.81%, 21.20%, 21.75%, and 18.68% for Fitchburg and roughly 40% statewide. Math is the largest gap — 8.48 points below the district and 28.39 points below the state — while science is the relative bright spot, rising to its highest recent level. Among nearby schools, only Gardner Middle School ranks close; Memorial Middle School in the same district serves a similar number of students (601) yet posts higher ELA (29.51%), math (23.88%), and civics (23.03%) rates, and Lunenburg Middle School, Groton Dunstable Regional Middle, and Luther Burbank Middle School all exceed 40% proficiency in ELA and math.
Subgroup data, which measures how well the school serves specific groups relative to other schools statewide, is uneven: the school ranks relatively high for homeless students (66th percentile, 3 stars) and English language learners (49th percentile, 2 stars), and above its overall level for special education students. Its student-teacher ratio of 11.3 in 2024–2025 is smaller than most nearby schools, including Memorial Middle School (13.0), suggesting staffing quantity is not the main constraint. Note that free/reduced-lunch percentages are not available in this data, and per-pupil spending figures only go through 2020–2021 ($15,802).
