Summary:
ZIP code 01504 in Blackstone, Massachusetts is home to a single middle school: Frederick W. Hartnett Middle School. It serves grades 4–7, enrolls 487 students, and belongs to the Blackstone-Millville district. Because it is the only middle school in the ZIP code, there are no in-ZIP peers to compare it against; the most useful comparisons are to its own district and to the state.
The school's clearest strength is that it outperforms its district in every reported 2025–2026 MCAS subject and grade comparison. Its rank has also improved steadily: from 272 of 493 (45th percentile, 2 stars) in 2023–2024, to 250 of 484 (48th percentile, 2 stars) in 2024–2025, to 221 of 478 (54th percentile, 3 stars) in 2025–2026 — moving above the 50th percentile and adding a third star. The district overall sits at 242 of 351, the 31st percentile with 2 stars. Science is the standout subject: all-grade science proficiency is 45.45%, versus 36.8% in the district and 40.98% statewide. Grade 7 ELA (45.45%) and Grade 5 math (44.55%) are also above both district and state.
Results are uneven by grade. The strongest state-relative results are Grade 7 ELA, 5.54 points above state, and Grade 5 math, 5.05 points above state. The weakest is Grade 6 ELA, 7.20 points below state; Grade 6 math and Grade 7 math also trail state by roughly 5 points. All-grade ELA (37.7%) and math (38.16%) remain below state by 2.33 and 2.95 points respectively, and science declined from 58.33% in 2024–2025. The student-teacher ratio is 15:1 (2024–2025) and per-student spending is $15,221 (2020–2021). Free/reduced lunch data are not available, so socioeconomic context cannot be assessed, and the grades 4–7 span is unusual for a middle school.
