Onaga-Havensville-Wheaton

The three schools in Onaga-Havensville-Wheaton serve students from prekindergarten through grade 12: Onaga Elementary has 164 students, Onaga Middle School has 76, and Onaga Senior High has 86. In 2025–26, every school’s all-grades results were above the state figures in English language arts (ELA), math, and science. The biggest difference among schools is in science: results range from 40% at Middle to 63% at Senior High, a 23-point gap, even though Middle is still 2 points above the state. The most important takeaway is that strong overall results hide a particularly uneven science picture.

Onaga Senior High stands out in math and science, with 53% proficiency in each subject, while Onaga Middle School leads in ELA at 58%, 6 points above Senior High and 12 points above the state. Onaga Elementary is second in science at 60%, but has the group’s lowest ELA and math results, at 47% and 44%. SchoolDigger ranks Senior High 28th of 340 Kansas high schools, in the 92nd percentile with five stars; Middle is 82nd of 368 middle schools, in the 78th percentile with four stars; Elementary is 292nd of 657 elementary schools, in the 56th percentile with three stars.

Recent changes favor ELA but show weaker math momentum: the unweighted average across the three schools rose 6 points in ELA from 2024–25 to 2025–26, while its math average fell 6 points. The ELA average’s lead over the state grew from 2 to 7 points; the math lead narrowed from 15 to 7 points. Elementary’s science score rose 27 points, while Middle’s fell 3; together, their average moved from 3 points below the state to 12 points above it. Grade-level results add useful detail: Elementary grade 4 ELA was 21 points below the state, and Middle grade 6 ELA was 3 points below, despite both schools’ above-state all-grades results. Senior High has the lowest student-teacher ratio, 9.8, and lowest free/reduced-lunch rate, 36%; Middle has the highest ratio, 14.9, while Elementary has the highest lunch rate, 54%. These figures are context, not explanations for performance; the schools serve different grades, and group averages count each school equally.
