Summary
Sarah W Gibbons Middle is a grades 7–8 school in Westborough, MA serving 610 students, and it has earned five stars in every year shown in its rank history, placing 26th of 478 Massachusetts middle schools — the 95th percentile — in 2025–2026. That keeps it firmly in the top 5–6% of middle schools statewide, though slightly below its late-2010s peak, when it occasionally reached the top 1–2%.
Academically, 2025–2026 MCAS proficiency is very strong: ELA 70.71, math 73.19, science 67.86, and civics 69.04, against state averages of about 40 in each subject — roughly 32 points above the state in math and 31 in ELA. Among nearby schools, Hopkinton Middle School ranks higher (14th of 478, 97th percentile) and leads in math, science, and civics, while P Brent Trottier (31st of 478) is close behind and edges Gibbons in science and civics. Gibbons is essentially tied with Hopkinton in ELA and clearly ahead of Oak Middle School (53rd), Ashland Middle (72nd), Grafton Middle (81st), and Robert E. Melican Middle School (117th). Science is the least distinctive subject — only 0.65 points above the Westborough district average, compared with 9.4 points in ELA and 5.2 in math.
Most student groups perform at a high level: male students rank in the 96th percentile, female students 93rd, English learners 89th, and special education students 87th. The clearest gap is among low-income students, whose percentile fell from 86th in 2024–2025 to 70th in 2025–2026; Hispanic students (71st) and multiracial students (70th) also trail the school's overall 95th percentile, though small group sizes can make year-to-year changes volatile. Gibbons has 10.5 students per teacher and spent $17,992 per student in 2020–2021. Hopkinton spends less with larger classes and still scores higher, suggesting instruction, curriculum, and school culture matter as much as staffing. The district's earlier-grades Mill Pond School shows lower ELA and math proficiency.
