Summary:
Elementary schools in this area consist of just one public school — Three Rivers Montessori School in Elk River, Minnesota — a K–6 school with 119 students that also operates as its own district, Three Rivers Montessori School.
Because it is the only school here, it is the standout by default, and its story is rapid improvement rather than top-tier results. Its rank percentile climbed from 15 in 2023–24 to 25 in 2024–25 and 49 in 2025–26, with its star rating rising from 1 star to 2 stars. Every reported all-grade subject improved between 2024–25 and 2025–26: Reading gained 16.75 percentage points, Math gained 13.85 points, and Science gained 10.91 points. In 2025–26, Math (45.1) is just above the state (44.9) and Reading (48.0) is just below the state (48.6), so both core subjects now sit near state averages. Science is the clear weakness, at 20.0 versus a state figure of 25.5. Grade-level results are uneven: 3rd-grade Math (57.9) is exactly at state, 4th-grade Math (55.6 vs 55.2) is above state, and 3rd-grade Reading (52.6 vs 46.8) is a bright spot. The largest gap is 5th-grade Math at 20.0 versus state 41.9, and 5th-grade Science is also below state at 20.0 versus 25.9. Upper-grade Reading and 6th-grade Math cannot be evaluated because the state suppressed those figures; a dash means unknown, not a weakness.
Context matters for interpreting these numbers: with 119 students across K–6, grade-level cohorts are small, so a few students can shift percentages considerably — which also explains some suppressed figures. The 2024–25 free/reduced lunch rate of 30.25% suggests a moderate economically disadvantaged population, and the 15.8 student-teacher ratio adds further context. Note also that school and district proficiency figures are identical since it is a single-school district, though the rankings differ slightly: the district is listed at 225 of 458, 51st percentile with 3 stars, while the school's 2025–26 rank history shows 441 of 869, 49th percentile with 2 stars.
