Summary:
Zip code 67428 has one listed school, Canton-Galva Junior/Senior High, serving grades 6–12 with 174 students. In 2025–26, its all-grades proficiency was 40% in English language arts (ELA), 31% in mathematics and 29% in science, compared with Kansas rates of 46%, 41% and 38%. ELA was closest to the state rate, while mathematics had the largest gap. The most important overall finding is that the school was below Kansas in all three subjects, by 6 points in ELA, 10 in math and 9 in science.
There is no meaningful local top-or-bottom comparison because this is the only school listed, but results vary considerably by grade. Grade 8 was a bright spot: Canton-Galva Junior/Senior High was above Kansas by 3 points in ELA, 1 in math and 2 in science. Some high-school results were much lower: grade 10 ELA was 12 points below the state, and grade 11 science was 14 points below. Across the grades reported, the school’s results spanned 21 points in ELA, 14 in math and 25 in science, so an all-grades figure does not tell the whole story for a particular grade.
Recent progress is strongest in ELA and science, while math remains a concern. From 2024–25 to 2025–26, the school’s ELA rate rose from 31% to 40%, and its gap with Kansas narrowed by 7 points; science rose from 22% to 29%, narrowing its gap by 10 points. Math rose from 29% to 31%, but its gap widened by 1 point as the state improved slightly more. SchoolDigger gives the school 1 star and ranks it 278th of 340 schools, in the 18th percentile; its percentile ranking fluctuated from 13th to 23rd and back to 18th over three years. Other context includes a 12.7 student-teacher ratio and a 37% free/reduced-lunch rate. The 2023–24 graduation rate was 93%, above Kansas at 90%, while 2025–26 chronic absenteeism was 47%, compared with 18% statewide.
