Summary:
Millbury, Massachusetts has two elementary schools serving a combined 909 students: Elmwood Street, which covers grades PK–2 with 455 students, and Raymond E. Shaw Elementary, which covers grades 3–6 with 454 students. Together they form a pipeline, with Elmwood feeding into Shaw, and their nearly identical enrollment suggests stable cohort sizes. Both belong to the Millbury district, which is ranked 254th of 351 districts in the state, at the 28th percentile with 1 star.
Raymond E. Shaw is the only one of the two with reported MCAS results, and math is its clear relative strength: all-grade math was above the state in both years, by 1.13 points in 2025–26 and 2.93 points in 2024–25, with 4th-grade math (+2.56 over state) and 5th-grade math (+4.71 over state) especially strong. English Language Arts is the weaker area, falling below the state by 4.42 points in 2025–26 and 4.28 points in 2024–25; 5th-grade ELA was 28.87% against a state figure of 38.15%. Shaw also outperformed its district in all three subjects in 2025–26. Even so, its overall rank slipped from 53rd percentile with 3 stars in 2023–24 to 46th percentile with 2 stars in 2025–26 — above its district context but slightly below the state median.
On resources, Shaw has a lower student-teacher ratio (12.8 vs. 14.7) and spends more per student ($18,986 vs. $17,459), though the spending figures are from 2020–2021 and Elmwood's PK–2 structure can bring different staffing and cost patterns, so cause and effect should not be assumed. Free/reduced lunch is not reported for either school, so economic disadvantage cannot be compared, and Elmwood has no test scores or rank history, meaning its academic performance cannot be assessed from this data.
