Summary
Marshall Middle School is a Billerica, MA middle school serving grades 5–7 with 596 students in a mid-sized suburban district northwest of Boston. In 2025–2026 it ranked 153rd of 478 Massachusetts schools—68th percentile, 3 stars—above its district’s overall standing of 175th of 351 (50th percentile, 3 stars). Its long-term trend is encouraging: after hovering around the 54th–62nd percentile from 2015–2016 through 2020–2021, it rose to 71st–72nd percentile and 4 stars in 2022–2024, then slipped to 68th percentile and 3 stars in 2025–2026.
On 2025–2026 MCAS tests, its all-grade ELA proficiency was 45.54%, above the district’s 41.81% and the state’s 40.03%; math was 42.16%, slightly above the district’s 41.69% and the state’s 41.11%. Science was a clear weakness at 38.63%, below the district’s 44.22% and the state’s 40.98%. Science fell 10.3 points from 48.95% in 2024–2025 while district and state science changed little, suggesting a school-specific decline. Because it serves grades 5–7, its science result reflects grade 5 science, making comparisons with grade 8 science schools imperfect. Grade-level results are uneven: 7th grade ELA (51.55%) and 6th grade math (48.44%) are strengths, while 7th grade math (34.02%) and 5th grade science (38.63%) lag.
Compared with nearby schools, the school is stronger than most Lowell middle schools in ELA, though James S Daley Middle School is stronger in math and has a higher 2025 rank. Its closest same-district peer, Locke Middle, ranks close overall (66th percentile, 3 stars) but posts higher 2025 proficiency in ELA (+1.3 points), math (+3.1), and science (+5.9), with a lower student-teacher ratio (10.8 vs. 11.7). It trails the top nearby schools: John Glenn Middle in Bedford is 92nd percentile with 5 stars, and Wilmington Middle School is 73rd percentile with 4 stars. Results for student groups are mixed: female students were 75th percentile, low socioeconomic students 67th, male students 57th, and special education students fell sharply to 27th percentile and 1 star in 2025–2026. It spent $20,717 per student in 2020–2021, higher than its same-district peer and similar to those two higher-ranked nearby schools.
