Hartnett Middle School (grades 4–7, 487 students) and Blackstone Millville Regional High School (grades 8–12, 534 students). This is an unusual configuration — fourth graders attend the middle school and eighth graders attend the high school — and there are no elementary or alternative schools in this list. The district as a whole ranks 242 of 351 in Massachusetts, at the 31st percentile with 2 stars.
Frederick W. Hartnett Middle School is the standout, earning 3 stars in 2025–2026 and ranking 221 of 478 middle schools (54th percentile). Its rank has climbed steadily from 272 of 493 in 2023–2024. It beat the district in all three core subjects in 2025–2026: ELA 37.70% proficient, Math 38.16%, and Science 45.45%. Science is its clearest strength, above the state's 40.98%, though it fell from 58.33% the prior year. Grade-level highlights include 7th grade ELA at 45.45%, above the state's 39.91%, and 5th grade Math and Science at 44.55% and 45.45%.
Blackstone Millville Regional High School is not a standout overall. It ranked 227 of 353 high schools (36th percentile, 2 stars) in 2025–2026 — up from 26th percentile in 2024–2025, but still below its 2023–2024 mark. Core scores trail the district and state: ELA 21.26%, Math 16.13%, and Science 32.28%. Bright spots are Biology End of Course at 38.60%, above district and state, a 91.9% graduation rate, a 5.1% dropout rate, and a lower student/teacher ratio (13.5 vs. 15.0). Notably, the high school spends slightly more per student ($15,928 vs. $15,221) yet posts lower proficiency. Free/reduced lunch data is blank for both schools, so it should be treated as unknown.
