Summary:
ZIP code 66423 has one listed elementary school, Mission Valley Elementary, serving prekindergarten through grade 6 and enrolling 236 students. In 2025–26, its proficiency results were below Kansas averages in ELA, math, and science, with science showing the largest gap. Because it is the only school listed, families cannot compare local schools against one another; the clearest takeaway is that the school’s latest results were below the state in all three subjects.
Mission Valley Elementary is both the area’s only school and its only possible standout—not a local leader or trailer. Its 2025–26 proficiency was 39% in ELA, 29% in math, and 24% in science, compared with 46%, 41%, and 38% statewide. That puts the school about 7 percentage points below Kansas in ELA, 12 points below in math, and 14 points below in science. It was roughly level with the Mission Valley district in ELA, but 7 points lower in math and 13 points lower in science. Grade-level results show some variation: fifth grade was closest to the state in both ELA and math, while fourth-grade math was 21 points below the state.
Results moved in different directions over the last two years: the school’s ELA score rose 3 points, while math fell 5 points and science fell 13 points. Its state gap narrowed in ELA, from 8 points to 7, but widened in math, from 5 to 12 points, and science, from 5 to 14 points. SchoolDigger’s statewide ranking also declined, from 449th of 653 schools (31st percentile) in 2023–24 to 524th of 657 (20th percentile) in 2025–26; its rating went from 2 stars to 1. The school’s 13.1:1 student-teacher ratio and 39% free/reduced-price lunch rate provide context, but there are no comparable local-school figures to show how distinctive they are.
