Summary:
ZIP code 56183 has just one school: Westbrook-Walnut Grove Secondary, a high school serving grades 7–12 with 198 students, part of Westbrook-Walnut Grove Schools in Westbrook, Minnesota. It is the only school in the ZIP, so it serves as the combined middle and high school for the area. Because there are no other schools to compare it with locally, the most useful comparisons are against district and state averages.
The school's clearest strength is getting students to graduation. In 2024–2025 it had a 95.8% graduation rate — matching its district and 10.9 percentage points above the state's 84.9% — and a 0.0% dropout rate, compared with 4.2% statewide. Eighth grade was the academic bright spot in 2025–2026: students scored above the state in math (56.3% vs. 42.3%), reading (53.1% vs. 50%), and science (19.4% vs. 16.7%). All-grade math also improved year over year, from 36.36% to 40.2%.
Overall test proficiency, however, trails Minnesota in all three subjects. Reading shows the widest gap: 33.3% for all grades versus 48.6% statewide, with 7th grade reading at 18.9% against the state's 43.5%. Math (40.2% vs. 44.9%) and science (21% vs. 25.5%) are below state but closer. The school holds a 2-star rating and ranked 306 out of 473 schools in 2025–2026 — the 35th percentile, below its district's 50th percentile. About 56.06% of students are eligible for free or reduced-price lunch, and the student-teacher ratio was 11.7. With only 198 students across six grades, yearly and grade-level results can shift noticeably from small changes in a single class.
