Summary:
ZIP code 55964 has just one elementary school: Plainview-Elgin-Millville Pk-3, located at 600 W Broadway in Plainview, MN. It serves prekindergarten through 3rd grade, enrolls 441 students, and belongs to the Plainview-Elgin-Millville district. That district ranks 101 of 458 in Minnesota — the 78th percentile — and holds 4 stars. Because there is only one elementary school in this ZIP, there are no local peers to compare against, so the most useful benchmarks are the district and the state.
For 2025–2026, the school's proficiency rates beat both benchmarks in the reported subjects. Math came in at 71.2 for all grades and 3rd grade, well above the district's 48.7 for all grades and the state's 44.9 for all grades. Reading was 61.5, above the district's 53.7 and the state's 48.6. Since the school serves PK–3 and MCA testing generally begins in 3rd grade, those "all grades" figures essentially reflect the tested 3rd-grade class — which is why they match the 3rd grade results exactly. Against the state, that is +26.3 points in math and +12.9 points in reading; against the district, +22.5 in math and +7.8 in reading.
Improvement is another bright spot. From 2024–2025 to 2025–2026, math rose from 59.38 to 71.2 (+11.82 points) and reading from 51.04 to 61.5 (+10.46 points), while district and state results stayed flat or slipped slightly. Reading also moved from 2.86 points below the district to 7.8 points above it. One caution: the 2024–2025 reading exam is labeled MCA-III and the 2025–2026 one MCA-IV, so that year-over-year reading comparison may not be exact. For context, 36.96% of students qualified for free/reduced lunch in 2024–2025, and the student/teacher ratio is 12.8:1. No test-score values were suppressed, bounded, or reported as ranges.
