Summary:

ZIP code 55987 covers Winona, Minnesota, and contains 13 schools: 5 elementary, 1 middle, 5 high and 2 alternative schools, enrolling 2,797 students. They are run by four operators — Winona Area Public School District (7 schools, about 2,389 students), Bluffview Montessori (209 students), Riverway Learning Community Charter (124) and Hiawatha Valley Education District (75). Enrollment is concentrated: Winona Senior High (849 students) and Winona Middle (665) together serve 54.1% of all students in the ZIP.

The clearest academic standout is Bluffview Montessori, the highest-ranked district in the ZIP (rank 91 of 458, 80th percentile, 4 stars). Its 2025–26 All Grades proficiency is 47.4% math, 60.7% reading and 26.2% science, with reading 12.1 points above the state; it also has the lowest free/reduced lunch rate (22.01%) and lowest student-teacher ratio (6.8) among standard schools. Two schools improved sharply: Washington-Kosciusko Elementary rose from 1 star to 3 stars, and its 57.1% math score is the highest reported All Grades math result in the ZIP; Winona Middle moved from 1 star to 2 stars.

Outcomes vary widely. Winona Senior High has a strong 90.7% graduation rate and 3.2% dropout rate, both better than state, but reading proficiency of just 23.9%. Riverway Secondary posts the ZIP's highest reading score (61.3%) despite the highest poverty rate (73.02%) and student-teacher ratio (26.8), while its math (21.2%) and science (13.3%) are low. Alternative programs face steep challenges: River Valley Academy Alternative Learning Center has a 40% graduation rate and 15% dropout rate. Many small and alternative schools have test scores suppressed by the state — treat those as unknown, not zero.
