Summary:
Zip code 66064 has two high-school options in Osawatomie, Kansas: Osawatomie High and Osawatomie Virtual School, both serving grades 9–12. The high school enrolls 295 students, compared with 18 at the virtual school. The clearest concern in the reported achievement results is science: proficiency is 25% at Osawatomie High and 0% at the Virtual School, while the state rate is 38%.
Osawatomie High has the only reported all-grades ELA and math results, at 41% and 37%, respectively, compared with state rates of 46% and 41%; ELA and math cannot be compared between the schools because the Virtual School has no reported results in those subjects. In science, Osawatomie High is 14 points below the state, and the Virtual School is 38 points below it; the gap between the schools is 25 points. Their attendance and dropout figures point in different directions: chronic absenteeism is 49% at the high school and 3% at the Virtual School, against 18% statewide, while the Virtual School’s dropout rate is 17%, compared with 1% statewide.
Osawatomie High’s ELA and math results improved substantially from 2024–25 to 2025–26: ELA rose 10 points and math rose 18 points, narrowing its gaps with the state from 14 to 5 points in ELA and from 20 to 4 in math. A grade-level comparison is more encouraging: in 10th-grade ELA and math, the school is essentially even with the state. SchoolDigger’s percentile ranking for the high school rose from 12 in 2023–24 to 45 in 2025–26. The schools also differ in reported context: the high school’s student–teacher ratio is 10.8 and its free/reduced-lunch rate is 56%, compared with 17% at the Virtual School; those figures describe differences, but do not explain achievement results.
