Summary

Powder Mill School is an elementary school in Southwick, MA serving grades 3–6 in the Southwick-Tolland-Granville Regional School District, enrolling 383 students. In 2025–2026 it ranked 469 out of 899 Massachusetts elementary schools, placing it in the 48th percentile with 2 stars—roughly the middle of the state. That is a real improvement over 2017–2019, when it sat in the 30th–35th percentile with 1–2 stars, though it has hovered near the middle since 2020–2021 and slipped relative to nearby schools this year.

Science is the standout: 51.16% proficiency, about 10 points above the state, with grade 5 science roughly 8 points above state. ELA has quietly climbed to 40.11%, essentially level with the state's 40.03%, and grade 5 ELA is very strong at 51.16% versus 38.15% statewide. Math is the clearest concern. At 36.81%, it is 4.3 points below the state and down from 43.35% in 2024–2025. Grade 4 math (28.24% vs. 43.20% state) and grade 6 ELA (29.70% vs. 40.26% state) are the weakest spots.

Subgroup results are uneven: low-income students rank in the 68th percentile with 3 stars—higher than the school overall and sustained for three years—while special education students rank in the 15th percentile (down from 28th) and the White students subgroup in the 28th percentile. Resources look favorable, with a student-teacher ratio of 10.8 (lower than most neighbors) and mid-pack spending of $15,317. Locally, Powder Mill trails Tatham, Clifford M Granger, Highland, William P. Sapelli Elementary, and Southampton Road, but leads James Clark School, Paper Mill, and Munger Hill. Nearby Woodland School serves PK–2 and has no current test data, making it more a feeder than a comparison. Note that neighbors mostly serve K–4 or PK–4, grade 6 has no local comparator, and free/reduced lunch data is not reported—so comparisons are directional.
