Summary
Douglas MacArthur Elementary School is a K–5 school in Waltham, MA, a suburban city west of Boston, serving 475 students in the Waltham district; the district ranks 231st of 351 Massachusetts districts (34th percentile, 2 stars), but the school itself ranks 372nd of 899 schools statewide (59th percentile, 3 stars) in 2025–2026. Its history shows volatility and a recent climb: a low of the 26th percentile (1 star) in 2017–2018, a peak of the 71st percentile (4 stars) in 2021–2022, then 50th, 56th, and 59th percentiles in the last three years — above the state median and improving modestly.
Test scores differ a lot by subject. In 2025–2026, 51.84% of students were proficient in English language arts, 43.75% in math, and 29.67% in science. ELA is the clear strength: it is about 14 points above the district and 12 points above the state, and it is the highest ELA score among nearby Waltham schools. Math is above district and state averages but less dominant. Science is the clear weakness — below the district and about 11 points below the state. MacArthur is the second-highest-ranked Waltham school in this nearby group, behind James Fitzgerald Elementary School (66th percentile, with 54.19% math and 45.45% science).
Science has declined sharply: 46.38% in 2022–2023, 42.47%, 35%, then 29.67%, while state science stayed roughly flat. Fifth graders are above the state in ELA and math but far below in science, suggesting a science-specific issue. Third-grade math is also below district and state averages. Several groups are improving: Hispanic students rose from the 12th to the 46th percentile, English language learners from 24th to 49th, and special education students from 24th to 55th. Low-income students remain at the 38th percentile versus 59th for the school overall — a notable gap. The student-teacher ratio is 11.4, higher than most nearby Waltham schools.
