Two schools stand out. Sarah W Gibbons Middle sits in the 95th percentile of Massachusetts middle schools and has held five stars for three straight years; in 2025–26 it led the district in all-grade ELA (70.71 vs. district 61.29) and math (73.19 vs. 68.01, with civics at 69.04). Westborough High is also five-star, ranking in the 91st–93rd percentile over three years, with a 96.6% graduation rate and 10th-grade scores far above the state — math 76.07 vs. state 43.73. Mill Pond School posts the strongest single math result in the file: 6th-grade math at 78.29, 35.70 points above the state. Its civics score is not reported.
Among the elementaries, J Harding Armstrong improved math by 4.66 points to 65.06, while Annie E Fales — the highest spender at $19,476 per student — saw the largest math decline, down 9.88 points to 62.03. Elsie A Hastings Elementary has the lowest current elementary proficiency (ELA 52.78, math 55.56) despite the lowest student–teacher ratio, 8.9. ELA fell almost everywhere year over year, most sharply at the high school (−10.53). Every school remains above state averages in every reported subject, but free/reduced-lunch data is blank for all schools, so economic context cannot be compared.
