Summary:
Zip code 55964 covers Plainview, Minnesota, and contains just two schools in the Plainview-Elgin-Millville district: Plainview-Elgin-Millville Pk-3, an elementary school serving grades PK–3 with 441 students, and Plainview-Elgin-Millville High, serving grades 9–12 with 414 students — 855 students combined, with no middle school or alternative school listed in this zip code.
The elementary school is the clear academic standout. In 2025–2026, 71.2% of its students were proficient in math, compared with 48.7% across the district and 44.9% statewide, and 61.5% were proficient in reading, versus 53.7% district and 48.6% state. Both subjects improved sharply over the prior year, up 11.82 points in math and 10.46 points in reading (though the reading exam label changed between years, so that comparison should be read with some caution). Notably, the elementary school has a higher free/reduced lunch rate than the high school, 36.96% versus 25.85%, and a lower student-teacher ratio, 12.8 versus 17.5 — about 37% smaller classes at the elementary level.
The high school is stable but mixed. It has held 4 stars and roughly the 81st percentile for three straight years, graduates 90.5% of students versus 84.9% statewide, and its science proficiency rose from 25.84% to 36.4%, now well above both district (27.8%) and state (25.5%). Math (47.6%) and reading (52.3%) sit slightly below district averages, and reading slipped about 3.5 points year over year. The biggest concern is the dropout rate of 8.4%, double the state's 4.2%, even though graduation remains above state. Parents should also note that these scores often reflect a single tested grade, and that grades 4–8 are not covered by any school in this zip code.
