Summary

Ambrose Elementary is a K–5 school serving 398 students in Winchester, Massachusetts, a Boston-area district ranked 7th of 351 in the state, and it is currently the 4th-ranked elementary school in all of Massachusetts — the top 0.5% statewide. Ambrose has earned 5 stars every year for a decade, and it has climbed steadily from 61st in 2022–23 to 34th, then 9th, and now 4th. In 2025–26, 77.3% of students were proficient in English language arts, 85.64% in math, and 85.45% in science — roughly twice the state's rates in each subject.

Among the schools nearby, Ambrose leads in both ELA and math. Its math score tops the next-closest school, Vinson-Owen Elementary (73.37%), by 12.3 points — the largest gap of any subject — and its ELA score (77.3%) beats Lynch Elementary (73.58%) and Lincoln Elementary (72.67%). Its science score ranks third in the group, just behind John A Bishop in Arlington (89.23%) and Lincoln (86.44%). Schools in other districts range widely: Peirce and M Norcross Stratton in Arlington, Harrington in Lexington, and Brooks School in Medford all post solid results but trail Ambrose, while Clyde Reeves in neighboring Woburn — about 1.7 miles away — sits near 47% in both subjects in a 2-star district. Even a strong district does not guarantee strong school-level results, and vice versa.

Ambrose's results are unusually even: its three grade-level math scores fall within 1.35 points of each other, pointing to school-wide teaching rather than one strong class. It also ranks among the top 3% of Massachusetts schools for its special education students. Two caveats for parents: free/reduced-price lunch data is not reported, so economic context can't be compared, and the per-pupil spending figure ($18,931, the highest among Winchester's elementary schools) dates to 2020–21, while test scores are from 2025–26.
