Summary:
Elementary schools in the Mendon-Upton district of Massachusetts serve two schools: Memorial School in Upton (grades K–4, 493 students) and Henry P Clough in Mendon (grades PK–4, 398 students), together enrolling 891 students. The district itself is ranked 101st of 351 districts statewide, at the 71st percentile with 4 stars — an above-average profile. Both schools share that district, but their individual results differ sharply.
Memorial School is the standout. Its 2025–26 rank is 129th of 899 schools (86th percentile, 4 stars), up from 168th (81st percentile) in 2024–25 and 264th (71st percentile) in 2023–24 — a steady climb. Its 2025–26 scores are strong across the board: 59.5% proficient in ELA and 66% in math, with 4th-grade math at 71.28%, the highest reported score in this data set. Memorial is above both the district and the state in every reported 2025–26 metric.
Henry P Clough is moving the other way: 432nd of 899 (52nd percentile, 3 stars) in 2025–26, down from 307th (66th percentile) in 2023–24. Its greatest weakness is ELA — 35.92% proficient overall, below the district's 47.82% and the state's 40.03%, and just 26.51% in 4th grade, the lowest reported score here. Math is a relative strength at 50.35%. Notably, Clough spends slightly more per student ($17,375 vs. $16,874) and has a similar student-teacher ratio (14.2 vs. 14.0), so on-paper resources do not explain the outcome gap. Clough also includes prekindergarten, so its enrollment is not directly comparable to a K–4 tested population. The percentile gap between the two schools has widened from 5 points in 2023–24 to 34 points in 2025–26.
