Summary
Wilmington Middle School is a grades 6–8 school in Wilmington, MA, a town north of Boston, serving 782 students. In 2025–2026 it ranks 129th of 478 Massachusetts middle schools, placing it in the 73rd percentile with 4 stars, and its district, Wilmington, ranks 76th of 351 districts statewide. The school has improved substantially over the past decade, rising from the 51st percentile in 2015–2016 to 78th in 2018–2019 and 76th in 2023–2025, before a slight dip to 73rd this year.
Wilmington Middle scores above the state average in every tested subject: 45.66% proficient in ELA, 51.07% in math, 47.33% in science, and 53.26% in civics — margins of roughly 5.6 to 13.5 points over Massachusetts, with math and civics as the clearest strengths. Among nearby middle schools it sits in the upper middle of the pack. It trails North Reading Middle, Arthur W Coolidge Middle, and Walter S Parker Middle, but outperforms the Tewksbury, Billerica, and Woburn schools. Against Marshall Simonds Middle, it is close in math, ahead in science, and behind in ELA and civics.
Results vary by grade. Sixth-grade ELA is a bright spot at 51.80%, while 7th-grade ELA is 40.95%, only barely above the state and district. Science showed the sharpest recent change, falling 7.26 points in a year from 54.59% to 47.33%. The school serves student groups unevenly: Hispanic students rank at the 84th percentile, and low-income and special-education students at the 66th and 64th, all above the state median, while Asian and White students rank at the 50th and 58th. Staffing looks favorable, with a 9.5-to-1 student-teacher ratio and $20,842 per-student spending in 2020–2021, higher than most nearby schools — suggesting the next gains will come from instruction and targeted support rather than more funding.
