Summary:
ZIP code 66521 has one middle school, Onaga Middle School, serving grades 6–8 and enrolling 76 students, so families do not have another local middle school for comparison. Its 2025–2026 all-grade proficiency was above Kansas in ELA, math, and science, though the science advantage was small.
With just one school on the list, Onaga Middle School is the local leader and trailing school by default, rather than a meaningful top-or-bottom performer in a local ranking. Its strongest subject was ELA: 58% proficient, 12 percentage points above Kansas and 6 points above the district. Math was 48%, 7 points above the state and 2 above the district. Science was 40%, just 2 points above Kansas but 13 below the district’s 53%, making it the school’s relative weak spot. Attendance was a bright spot: reported chronic absenteeism was 2%, compared with 13% in the Onaga-Havensville-Wheaton district and 18% statewide.
Recent results show a strong ELA gain but a notable math decline. From 2024–2025 to 2025–2026, Onaga Middle School’s ELA proficiency rose 10 percentage points, widening its lead over Kansas from 4 to 12 points. Math fell 11 points as the state rose 2, shrinking Onaga’s advantage from 21 to 7 points; science declined 3 points, while Kansas also declined 3. Grade-level results add important context: sixth grade was below the state in both ELA and math, while seventh and eighth grades were above it in both. SchoolDigger ranked the school 59th of 363 in 2024–2025 and 82nd of 368 in 2025–2026; the district has four stars and ranks 39th of 268. Other reported context includes a 14.9 student-teacher ratio and a 46% free/reduced-lunch rate.
