Summary:
ZIP code 56726 contains exactly one high school — Greenbush-Middle River Secondary, serving grades 7–12 with 102 students in the small rural community of Greenbush, Minnesota, as part of the Greenbush Middle River Schools district. Because it is the only school in this area, there are no other local high schools to compare it against; the more useful comparison is between this school and statewide averages.
The school's strongest results are in graduation and dropout outcomes: 91.6% of students graduated in 2024–25, well above the state's 84.9%, and the dropout rate was 0.0% versus the state's 4.2%. Science is a relative bright spot, with All Grades Science at 32.4% in 2025–26 (above the district's 23.2% and the state's 25.5%) and End-of-Course Science at 47.1%, far above the state's 35%. Middle-school Math also looks solid, with 7th and 8th grade both at 47.1%, above state averages. The school's latest rank is 226 of 473 schools — 52nd percentile with 3 stars — up from 2 stars in the two prior years.
Reading is the clearest area of concern. All Grades Reading stood at 31.4% in 2025–26, well below the state's 48.6%, and 7th, 8th, and 10th grade Reading were all below state as well — a sharp reversal from 2024–25, when Reading was 52.17% and above the state's 49.59%. Overall Math was 41.7%, slightly under the state's 44.9%, with 11th grade Math at 28.6% versus the state's 35.3%. In a school of 102 students, percentages can swing widely from year to year, so families should look at multi-year trends rather than any single result.
