Summary:
Onaga has three schools serving prekindergarten through grade 12, with 326 students across elementary, middle, and high school. In 2025–2026, the schools’ average proficiency was above Kansas in all three subjects: 53% in ELA versus 46% statewide, 48% in math versus 41%, and 54% in science versus 38%. Science had the largest average advantage, 16 percentage points, but also the widest spread among schools. The main takeaway is that Onaga’s overall results are above state levels, but performance varies considerably by school and subject.
Onaga Senior High has the strongest all-grades profile in math and science, with 53% proficient in each subject and 63% in science; its results were 12 points above state in math and 25 points above in science. Onaga Middle School leads in ELA at 58%, 12 points above state, but has the lowest science result at 40%—just 2 points above state. Onaga Elementary is above state in all-grades results, including 60% in science, but its fourth-grade ELA and math results were 29%—21 and 15 points below state, respectively—while fifth grade was above state in all three reported subjects.
Results over time show gains in the area’s advantage over Kansas in ELA and science, but a narrower advantage in math: the school-average leads shifted from 2 to 7 points in ELA, 15 to 7 in math, and, for the two schools with comparable science results, from 3 points below state to 12 points above. SchoolDigger ranks Onaga Senior High at the 92nd statewide percentile, up from the 89th three years earlier; its current rank is 28 of 340. Elementary’s percentile rebounded to 56, while Middle’s moved down to 78. All three schools share SchoolDigger’s 4-star rating and district rank of 39 of 268. Ratios also vary: 9.8 students per teacher at High, 12.3 at Elementary, and 14.9 at Middle.
