of 473 Minnesota High Schools

Better than 92% of Minnesota high schools

Summary

Kasson-Mantorville Senior High is a public high school in Kasson, Minnesota, serving 671 students in grades 9–12 as part of the Kasson-Mantorville School District in a small community near Rochester. It ranks 37th of 473 Minnesota high schools in 2025–2026 — the 92nd percentile, or 5 stars — while its district ranks 24th of 458. Its rank history is striking: after a 2-star year in 2021–2022, when it placed 274th of 472, it has stayed in the top decile for four straight years, peaking at 15th of 450 in 2024–2025.

Graduation outcomes are among the school's strongest features. In 2024–2025, 96.7% of students graduated and just 0.6% dropped out, well ahead of Minnesota's 84.9% and 4.2%. Test scores also exceed state averages in all three high-school subjects: math 52.8%, reading 59.6%, and science 45.6%. Among nearby schools, Kasson-Mantorville posts the highest math proficiency — ahead of Byron Senior High School's 44.7% — and is essentially tied with Byron in reading (59.6% vs. 59.7%). Science is the clearest gap: Byron reaches 61.0%. Class sizes have improved too, with a student–teacher ratio of 17.2, down from 21.3 in 2022–2023.

Two things are worth watching. First, scores have softened from 2024–2025 peaks — reading fell from 72.11% to 59.6% and science from 52.74% to 45.6% — and math, while well above the state, sits below the district's 57.1%. Second, subgroup results are strong for most groups, including low-income students (94th percentile) and Hispanic students (93rd percentile), but special education students rank at the 21st percentile, down sharply from 74th the year before. With a free/reduced lunch rate of 20.12% — higher than Byron's but far below John Marshall High School's 40.74% — the school produces notably strong outcomes.
