Summary:
Zip code 01588 covers Whitinsville, Massachusetts, where all three public schools — Northbridge Elementary School (PK–5), Northbridge Middle (6–7), and Northbridge High (8–12) — belong to the Northbridge district and together enroll 1,838 students. The elementary school alone has 973 students, more than the middle and high schools combined, and free/reduced lunch information is blank for all three schools, so family-income comparisons are not possible from this data.
Northbridge Elementary School has the strongest test-score profile: in 2025-26 it beat the district in ELA (36.62%), Math (37.79%), and Science (39.16%), while still trailing the state in all three. Results vary sharply by grade — 5th grade ELA (44.76%) and 4th grade Math (43.92%) were at or above state levels, but 4th grade ELA (29.05%) and 5th grade Math (29.37%) fell well below state. School-wide averages hide very different grade-level needs.
Northbridge High posts the best high-school outcomes — an 85.8% graduation rate, an 11.3% dropout rate below the district's 11.7%, the lowest student/teacher ratio (10.7), and the highest per-student spending ($17,485) — yet science is its clearest weak spot: 10th grade Science 25.69% and Biology EOC 24.49%, both far below state. Northbridge Middle is the most stable, holding around the 45th percentile for three years on the lowest spending ($14,657), but its scores generally sit below district and state. Notably, the Northbridge district ranks 255 of 351 (27th percentile, 1 star) while each school shows 2 stars and percentiles in the low-to-mid 40s, and spending and staffing levels do not line up simply with results.
