Summary:
Zip code 66090 has one middle school, Riverside Middle School in Wathena, serving grades 6–8. With no other middle schools listed locally, families can compare Riverside’s results with Kansas and its district, but not with another school in the ZIP code. In 2025–26, Riverside was below the state in all three all-grade subjects: 42% in ELA versus 46% statewide, 33% in math versus 41%, and 35% in science versus 38%. The most important finding is that math is Riverside’s largest statewide shortfall, at 8 percentage points below Kansas.
Within Riverside, grade-level results show both bright spots and a clear area of concern. Seventh-grade ELA reached 46%, about 2 points above the state’s 44%, while sixth-grade math was 43%, about 2 points above the state’s 41%. Eighth-grade math was the weakest result: 28% proficient, compared with 40% statewide, a 12-point gap. Since Riverside is the only school listed, there is no local school-to-school leader or lowest-performing school to identify. These grade differences also show why the all-grade results do not tell the whole story.
Results changed in different directions from 2024–25 to 2025–26: Riverside gained 4 points in ELA and science, but fell 4 points in math. Its equal-weight average across the three subjects rose by 1 point, and the gap with Kansas narrowed from 6 points to 5; however, the math gap widened by 6 points while the ELA and science gaps narrowed. SchoolDigger ranked Riverside 216th of 368 schools in 2025–26, at the 41st percentile, after a 45th-percentile ranking the prior year. The Riverside district was ranked 200th of 268 by SchoolDigger and received 1 star. Other context includes 143 students, a 12.9 student-teacher ratio, and a 58% free/reduced-lunch rate; chronic absenteeism was 15%, below the district’s 19% and Kansas’s 18%.
