Glenbrook Middle is a public middle school in Longmeadow, MA, serving grades 6–8 with about 327 students. It is part of the Longmeadow district, which ranks 52nd of 351 districts statewide. Glenbrook is a consistent high performer: in 2025–2026 it ranked 57th of 478 Massachusetts middle schools (88th percentile, 4 stars), and it has earned 4 stars in every year listed. On 2025–2026 MCAS Next Generation tests, proficiency was 60.13% in English Language Arts, 69.16% in Math, 72% in Science, and 62.38% in Civics — far above state averages of 40.03%, 41.11%, 40.98%, and 39.77%.
Glenbrook's clearest edge over nearby schools is in Math and Science. Its Math proficiency tops Williams Middle, its same-district neighbor, by 11.58 points, Birchland Park by 19.50 points, and Agawam's Roberta G. Doering School by roughly 35 points. Eighth-grade Math is a standout at 80% proficient, versus 59.63% at Williams and 49.74% at Birchland Park. Civics is the one relative soft spot: 62.38% beats the state average by 22.61 points but trails both the district (64.06%) and Williams (67.86%). ELA is strong overall but uneven by grade, with 7th-grade ELA at 50.96%.
Glenbrook also stands out for how well it serves specific student groups. Its low-income subgroup ranks in the top 8% statewide (5 stars), its special education subgroup in the top 11%, and its Asian student subgroup reached the top 3% in 2025–2026. Notably, Glenbrook spends less per student ($15,076 in 2020–2021) than Williams, Birchland Park, Agawam, and most Springfield schools, and its student–teacher ratio of 12.2 is not the lowest among them. Overall, Glenbrook is the clear academic leader among nearby schools, with Math and Science as its strengths and Civics plus grade-level ELA variation as the areas to watch.
