Summary:
ZIP code 01075 covers South Hadley, Massachusetts, and contains five schools serving students from pre-kindergarten through grade 12: two elementary schools (Plains Elementary for PK–1 and Mosier for grades 2–4), one middle school (Michael E. Smith Middle School, grades 5–8), and two high schools (South Hadley High, grades 9–12, and Pioneer Valley Performing Arts Charter Public School, grades 7–12). Together they enroll 2,017 students; the four South Hadley district schools serve 1,620 of them, while the charter school enrolls 397 under Pioneer Valley Performing Arts Charter Public (District).
At the high school level, the two schools trade strengths. Pioneer Valley Performing Arts Charter Public School has the higher graduation rate (94.2% vs. 93.2%) but also the higher dropout rate (4.3% vs. 3.0%), and it posted the strongest current results in the group: 54th percentile with 3 stars in 2025–26, up from 43rd percentile, with 10th-grade ELA and Science both above state averages. South Hadley High has the lowest student-teacher ratio in the ZIP code at 8.5, but its rank slid from the 63rd percentile with 3 stars in 2023–24 to the 49th percentile with 2 stars in 2025–26, and its 10th-grade Science sits at 30.10%, about 10.4 points below the state. Its 10th-grade Math (42.06%) is near the state (43.73%), though down sharply from 51.64% a year earlier.
Math is the area-wide weak spot. Michael E. Smith Middle School, the largest school at 505 students, fell from the 56th percentile with 3 stars to the 42nd with 2 stars, and its all-grade math is 24.77% against the state's 41.11%. Mosier is the clearest improver, rising from 1 star to 2 stars, with math at 32.55% — above the South Hadley district average of 27.06% but still below the state. Plains Elementary has no MCAS scores because it serves PK–1, but it has the highest per-student spending ($18,585) and the highest student-teacher ratio (13.7). Free/reduced-lunch figures are blank for all five schools, so economic comparisons are not possible here.
