Summary:
Zip code 67361 has two schools serving prekindergarten through grade 12: Sedan Elementary (PK–5, 178 students) and Sedan High (grades 6–12, 182 students); there is no middle school. Because the schools serve different grade spans, their all-grades test results are not like-for-like comparisons. The most important finding is that the two schools have sharply different academic profiles: in 2025–26, elementary proficiency was well above state rates in all three subjects, while the high school’s all-grades rates were below state rates in all three.
Sedan Elementary stands out: its all-grades proficiency was 65% in ELA, 62% in math and 44% in science, exceeding state rates by 19, 21 and 6 percentage points, respectively. Sedan High recorded 38% in ELA, 30% in math and 31% in science—7, 11 and 7 points below state rates. The elementary school’s rates were higher by 26 points in ELA, 33 in math and 14 in science. SchoolDigger ranked the elementary school 138th of 657 (79th percentile, four stars) and the high school 204th of 340 (40th percentile, two stars). High-school grade results include exceptions: grades 6 and 7 ELA and grade 7 math were above state results, as was grade 11 science; grade 8 math was especially low at 17%, 23 points below state.
Recent trends run in opposite directions: from 2024–25 to 2025–26, Sedan Elementary fell 9 points in ELA, 7 in math and 25 in science, while Sedan High rose 8, 2 and 10 points. The equal-weight averages of the schools’ results remained above state rates in ELA and math, but the advantage narrowed from 8 to 6 points in ELA and from 10 to 5 in math; science shifted from 4 points above to 1 point below. SchoolDigger’s rankings reflect the different trajectories: the high school rose from the 11th percentile in 2023–24 to the 40th in 2025–26, while the elementary school, after reaching the 96th percentile, was at the 79th. The high school also had a 96% graduation rate, 7 points above state, alongside higher chronic absenteeism (20% versus 18% statewide). Its student-teacher ratio was 8.5, compared with 10.2 at the elementary school.
