Summary
William Mitchell is a K–5 elementary school at 187 Brookline Street in Needham, Massachusetts, serving 424 students as part of the Needham district. In 2025–2026 it ranked 118th of 899 elementary schools statewide — the 87th percentile, with 4 stars. That is a strong statewide position, and its proficiency rates beat state averages in English Language Arts (59.64%), Math (67.71%), and Science (69.74%), compared with statewide averages near 40%–41% in each subject.
Within its own high-performing community, though, William Mitchell sits below the district's overall 94th-percentile standing, and it trails most nearby Needham schools, including Newman Elementary (95th percentile), Broadmeadow (92nd), and Sunita L. Williams Elementary (92nd), though it edges out John Eliot (86th). Nearby schools in other districts — Joseph E Fiske (99th percentile), A E Angier (96th), and Schofield (96th) — rank higher still. ELA is the clearest area to watch: 59.64% is about 9.4 points below the district, and third-grade ELA (54.76%) is nearly 15 points below the district and below every nearby Needham peer. Math is mixed — below district overall, but fifth-grade math (76.32%) is above district and the highest among nearby Needham schools. Science is a relative strength, above the district average.
Scores declined from 2024–2025 in all three subjects — steeper than the district's own dip — and the school's rank moved from 95th percentile (5 stars) to 87th percentile (4 stars). Grade-level results vary, so needs look targeted rather than school-wide. The strongest subgroup result is for special education students (92nd percentile, 5 stars). Reported per-student spending of $19,506 (2020–2021) is the lowest in this comparison group, and the student-teacher ratio is 12.5.
