Summary:
Wellesley has one middle school, Wellesley Middle, serving grades 6–8 with 919 students. It belongs to the Wellesley district, which ranks 5th of 351 Massachusetts districts (99th percentile, 5 stars). Because it is the only middle school in the area, it is the sole option for families here — and it is an exceptionally strong one. It has been ranked among the top middle schools in the state for three consecutive years: 11th of 493 in 2023–2024, 12th of 484 in 2024–2025, and 7th of 478 in 2025–2026, each year at the 98th–99th percentile with 5 stars.
On the 2025–2026 MCAS Next Generation tests, proficiency rates far exceed state averages. Math is the strongest subject at 80.95% proficient, versus 41.11% statewide, followed by science at 78.62% (state: 40.98%), English language arts at 75.42% (state: 40.03%), and 8th-grade civics at 77.63% (state: 39.77%). Eighth grade is remarkably balanced: 81.37 in ELA, 81.46 in math, 78.62 in science, and 77.63 in civics. Math and science both improved year over year (math up 5.50 points, science up 7.49 points), and science moved above the district average after trailing it in 2024–2025.
The one watch item is ELA, which slipped from 77.03 to 75.42 and sits just under the district average of 75.70. The drag comes mainly from grades 6 and 7 (72.47 and 72.11), while 8th-grade ELA stands at 81.37 — still about 32 points above the state. Resources look favorable: a student-teacher ratio of 8.9 and spending of $23,154 per student in 2020–2021, though that spending figure is several years old. The free/reduced-lunch percentage is blank in this data, so it is unknown rather than zero, and no demographic breakdowns are provided.
