Summary:
ZIP code 55901 in Rochester, Minnesota, is home to just one high school in this data set: John Marshall High School, a large public school serving grades 9–12 with 1,549 students in the Rochester Public School District.
Because John Marshall is the only high school in this ZIP code, there is no local peer to compare it against, so the most useful benchmarks are its own district and the state of Minnesota. Its clearest strength is completion: the graduation rate is 89.8%, above the district's 86.2% and the state's 84.9%, and the dropout rate is 1.7%, well below the district's 3.0% and the state's 4.2%. The school has been rated 2 stars in each of the last three reported years, with percentile ranks of 44, 48, and 46 — placing it in the middle-to-lower-middle range of Minnesota high schools, slightly below the district's own 3-star, 50th-percentile rating. About 40.74% of students qualify for free or reduced lunch.
Academically, math is the largest gap: 28.4% of students were proficient at the all-grades level in 2025–2026, compared with 41.2% in the district and 44.9% statewide. Reading dropped from 48.32% in 2024–2025, when it was slightly above the district, to 41.6% in 2025–2026, now 5.5 points below the district and 7.0 points below the state; the exam label also changed from MCA-III to MCA-IV, so that one-year comparison should be read with caution. Science is mixed: at the all-grades level, 26.2% were proficient, marginally above the district's 25.4% and the state's 25.5%, but on the science End of Course exam the same 26.2% falls below the district's 32.5% and the state's 35.0%. The 2024–2025 science result is suppressed by the state, and the student-teacher ratio is not reported, so those gaps limit trend and staffing analysis.
