Summary:
Zip code 66056 has one elementary school, Jayhawk Elementary, serving prekindergarten through sixth grade in Mound City, with 311 students. There is no other school in the list to compare with it, so its results are best understood against Kansas and across its own grades. In 2025–26, the school was above the state in English language arts and math but below it in science: about 6 percentage points above in ELA, 3 points above in math, and 8 points below in science. The most important finding is that the latest results are mixed by subject, with science the clearest concern.
There is no school-to-school top or bottom performer in this zip code, but grade-level results show a clear bright spot and areas to watch. Sixth-grade results were strong: about 60% were proficient in ELA, compared with 42% statewide, and about 60% in math, versus 41% statewide. Other comparisons were weaker: fourth-grade ELA was about 39%, versus 50% statewide; fourth- and fifth-grade math were 8 and 9 percentage points below state results. Fifth-grade science was about 30%, compared with 46% statewide—a gap of 16 points. These contrasts show why the all-grades averages do not describe every grade equally well.
Results declined from 2024–25 to 2025–26 in all three subjects, with the largest drop in science: ELA fell about 2 percentage points, math about 3, and science about 21, while statewide science fell about 3 points. The school’s state gaps also narrowed or reversed; science went from 10 points above the state to 8 points below. SchoolDigger’s rating moved down from 249th of 656 schools (62nd percentile, 3 stars) to 349th of 657 (47th percentile, 2 stars). Chronic absenteeism was 30.1% at the school, compared with 29.5% in the Jayhawk district and 17.8% statewide. The student–teacher ratio was 12.3, and the free/reduced-lunch rate was about 59%—context for families, not an explanation of results.
