Summary:
ZIP code 55057 is served by a single public middle school: Northfield Middle, a grades 6–8 school with 845 students located at 2200 Division St S in Northfield, part of the Northfield Public School District. Because it is the only middle school in the ZIP code, all middle-grade students in the area attend this one campus, so its results are the full picture for local middle school performance.
Northfield Middle has been a 5-star school in each of the last three reported school years and ranks in the top 10% of Minnesota middle schools: 52nd of 546 schools (90th percentile) in 2025–2026, 44th of 519 (92nd percentile) in 2024–2025, and 32nd of 545 (94th percentile) in 2023–2024. Reading is its strongest subject, with all-grades proficiency of 60.6% versus 48.6% statewide — a gap of 12.0 points — and 6th-grade Reading at 68.8% against the state's 53.4%. Math proficiency is 53.8%, which is 8.9 points above the state, but it dropped 4.43 points from the prior year, a steeper decline than the district's 0.96-point and the state's 0.31-point drops. Science, at 27.4%, is the lowest proficiency area, yet it is still 1.9 points above the state all-grades figure and 10.7 points above the 8th-grade state score of 16.7%.
For context, 28.28% of students qualified for free/reduced-price lunch and the student/teacher ratio was 19:1 in 2024–2025. Against its district, the school looks slightly behind at the all-grades level (Math −5.1 points, Reading −0.4, Science −9.0), but at the actual middle-grade level it ties or beats the district in every reported subject and grade — a reminder that district all-grades averages include grade levels outside this 6–8 school. The two items worth watching are the slow percentile drift from 94 down to 90 and the sharper year-over-year Math decline.
