Three Rivers Montessori School

In this area, Three Rivers Montessori School is the only school, an elementary school serving grades K–6 with 119 students in Elk River, MN. It is also its own district, Three Rivers Montessori School, so district and school test scores are identical. Because there are no other elementary, middle, high, or alternative schools in this data set, parents should focus on this school’s own trends compared to Minnesota state averages.

The school has shown a strong upward trajectory: it moved from the 15th percentile in 2023–2024 to the 49th percentile in 2025–2026, a 34-point gain, with its star rating rising from 1 to 2 stars. Its rank improved by 306 positions. In 2025–2026, all-grade math is 45.1% proficient (0.2 points above state) and reading is 48% (0.6 points below state), after both were about 14–18 points below state in 2024–2025. Science improved from 9.09% to 20% but remains 5.5 points below the state average of 25.5%.

Grade-level results vary: 3rd grade reading is 52.6% proficient (5.8 points above state), 4th grade math is 55.6% (slightly above state), and 3rd grade math is 57.9% (equal to state). However, 5th grade math is 20% versus 41.9% state, a 21.9-point gap, and 4th grade reading is 44.4% versus 48.8% state. Science at 5th grade is 20% versus 25.9% state. Reading for 5th and 6th grades and math for 6th grade are suppressed by the state, meaning those results are unknown, not zero. With 119 students, small cohorts can cause large swings, so one strong year should be watched for sustainability. Also, the district is ranked 225 of 458 (51st percentile, 3 stars) while the school’s latest rank is 441 of 869 (49th percentile, 2 stars), showing that rankings depend on the comparison group.
