Summary
Miller School is a public elementary school in Holliston, MA, serving grades 3–5 with 649 students in a district that ranks 50th of 351 Massachusetts districts. It is a stable, above-state school in a strong district: on 2025–2026 MCAS Next Generation tests, it scored above Massachusetts in English language arts, math, and science, but below its own district average in all three subjects. Its 2025–2026 rank was 288th of 899 schools, the 68th percentile with 3 stars, after several years in the 68th–69th percentile range. That is an improvement from the late 2010s but below its 2020–2021 peak.
Important strengths and watch items include clear grade-level differences. Fifth-grade math is a standout: 66.34 versus the state’s 39.50, and fifth-grade science is also strong at 57.77 versus the state’s 43.07. Fourth-grade math is the clearest relative weakness, at 39.83, below the state’s 43.20 and almost even with the district’s 40.00. Results for English Language Learner students improved dramatically, from the 1st percentile in 2023–2024 to the 86th percentile with 4 stars in 2025–2026, while Special Education and Low Socio Economic Status results have been relatively stable, around the 57th–70th percentile. Female and male students perform similarly.
Compared with nearby schools, Miller School is a solid middle-to-upper performer, but not the top local choice on test scores. It trails Burke/Memorial Elementary School in ELA and math, and it is behind Hopkins Elementary School and Pine Hill, which post much higher ELA, math, and science results. It is very similar to David Mindess, though Miller School’s science score is stronger. Miller School clearly outperforms Clyde F Brown and Harmony Grove Elementary. Its per-student spending, $14,793, is the lowest in this comparison group, with a mid-range student-teacher ratio of 13.1; nearby Hopkins Elementary School gets stronger results with similar spending, while Harmony Grove Elementary spends much more with weaker outcomes. Placentino Elementary, the PK–2 school sharing its address, is a feeder rather than a direct MCAS comparator.
