Summary:
Medfield is a PK–12 public school district in Massachusetts with five schools — three elementary, one middle, and one high school — serving 2,478 students, and the district as a whole is rated 5 stars, ranking 12th of 351 districts in the state (97th percentile). The district is one of the highest-performing in Massachusetts, though performance varies by school and grade level.
Medfield Senior High is the standout: it ranks 7th of 353 high schools in 2025–2026 (98th percentile), up sharply from 25th the prior year. Its 10th-grade proficiency is roughly double the state's — about 80% in ELA, 81% in math, and near 90% in science and biology, with a 97.8% graduation rate and 1.1% dropout rate. Thomas Blake Middle ranks 24th of 478 (95th percentile), with civics at 80.79% and science at 77.27%; math is its relative soft spot at 70.24%, just below the district's 72.04%. Dale Street ranks 65th of 899 (93rd percentile) but has slipped recently. Ralph Wheelock School posts strong 3rd-grade results, and Memorial School serves PK–1 and therefore has no state test scores in this data.
Looking at trends, the high school is clearly rising, while Dale Street fell by about 5 points in ELA and math and 12.5 points in science year over year, and Ralph Wheelock's math dropped about 6 points. Even so, every school with test data remains well above state averages in every subject. Thomas Blake Middle has the highest per-student spending and lowest student-teacher ratio, while the two early-elementary schools have the largest classes. Note that free/reduced-lunch percentages are blank for all schools here, so socioeconomic context is unavailable and those blanks should not be read as 0%.
