Summary:
ZIP code 66531 has two listed public schools: Riley County Grade School, serving prekindergarten through grade 8, and Riley County High School, serving grades 9–12. Both schools are above state proficiency rates in every reported subject for 2025–26. The most important finding is that both compare favorably with the state, although the high school’s science result is its closest margin: 9 percentage points above the state, compared with the grade school’s 26-point lead.
Riley County Grade School leads the two schools in all three reported subjects, with 69% proficiency in ELA, 69% in math and 64% in science; the high school reports 63%, 59% and 47%. The gap between the schools is largest in science at 17 points, followed by 9 points in math and 6 in ELA.

From 2024–25 to 2025–26, the grade school’s ELA and science results fell by 1 and 3 percentage points, while math rose by 1; the high school’s ELA rose by 4 points and math fell by 1. Across the two schools, the math advantage over the state narrowed by 2 points. The grade school has 514 students, a 12.9 student-teacher ratio and a 23% free/reduced-lunch rate; the high school has 232 students, a 10.4 ratio and a 21% rate. High school chronic absenteeism was 10%, below the state’s 18%; the grade school’s 16% was below the state but above the district’s 14%. Because the schools serve different grade spans, their All Grades results are not a same-grade comparison.
