Schools in Zip Code 56143

Zip code 56143 has two schools — one elementary and one high school — both part of the Jackson County Central School District in Minnesota, together serving about 682 students, with no middle or alternative school listed in this area.

Riverside Elementary serves PK–3 with 350 students, a 13:1 student-teacher ratio, and 40% free/reduced lunch. It stands out for early reading: in 2025-2026 its all-grades reading score of 55.4 was 6.8 points above the state (48.6) and 6.7 points above the district (48.7), and its 3rd-grade reading of 55.4 was 8.6 points above the state 3rd-grade figure of 46.8. Math is subtler. The all-grades math score of 55.4 beat the state (44.9) by 10.5 points, but because the school only serves PK–3, that figure is essentially the 3rd-grade score — and 3rd-grade math was 2.5 points below the state's 57.9. Reading jumped 12.22 points, from 43.18 in 2024-2025 to 55.4, while math slipped 4.83 points from 60.23. Its older rank history shows improvement, from 41st percentile / 2 stars in 2016-2017 to 67th percentile / 3 stars in 2018-2019.

Jackson County Central Senior High serves grades 9–12 with 332 students, a 15.9:1 ratio, and 35.24% free/reduced lunch. Completion results are its strength: a 94.1% graduation rate against the state's 84.9%, and a 2.3% dropout rate against 4.2% statewide. Reading is solid too — 50.7 in 2025-2026, above district and state, with 10th-grade reading 8.2 points above state — though it fell from 55.41. Math and science are weaker: all-grades math of 34.3 trails the state by 10.6 points, though 11th-grade math (34.3 vs. state 35.3) is only 1 point behind. Science dropped sharply from 34.72, which was 8.57 points above state, to 19.1, which was 6.4 points below, with Science End of Course at 19.1 vs. state 35.0. Its rank fell from 70th percentile / 4 stars to 53rd percentile / 3 stars, below the district's 65th percentile. In short, the elementary leans on early reading while the high school relies on completion outcomes.
