Summary
Isanti Middle School is a grades 6–8 school in Isanti, Minnesota, serving about 449 students as part of the Cambridge-Isanti Public School District, which is ranked in the middle of Minnesota districts statewide.
The school currently ranks 250th of 546 Minnesota middle schools, placing it in the 54th percentile with a 3-star rating — above average statewide, but below its own historical peak in the 70th percentile a decade earlier. It has rebounded from the 42nd percentile in 2023–2024. On 2025–2026 state tests, math proficiency was 38.8% (district 43.2%, state 44.9%), reading was 44.1% (district 42.1%, state 48.6%), and science was just 10.8% (district 22.7%, state 25.5% on all-grades figures; 8th grade 10.8% vs. state 16.7%). Reading is the one subject where Isanti beats its district average, though it remains below the state. Science is the clear outlier, and it has been low for years — 15.09%, 14.61%, 8.96%, then 10.8% — so it looks systemic rather than a one-year dip.
Compared with nearby schools, Isanti sits in the middle. It outranks North Branch Area Middle School and Art & Science Academy Middle School but trails Cambridge Middle School, Oak View Middle, Zimmerman Middle, Princeton Middle School, and St. Francis Middle. Cambridge Middle School, its same-district neighbor just 4.24 miles away, scores higher in every subject (math 49.3%, reading 53.6%, science 20.4%) despite similar free/reduced-lunch rates — while Isanti has a lower student-teacher ratio, 14.1 versus 17.1, and lower than most nearby middle schools. Grade-level results are uneven: 8th grade math and reading are above state, but 7th grade reading and math and 8th grade science lag. The school stands out for its work with low-income students, who rank in the 76th percentile statewide, while special education students rank in the 26th percentile.
