Summary
Decatur Community Junior/Senior High serves 144 students in grades 7–12 in Oberlin, Kansas. Its latest results put it below state and district proficiency rates in English Language Arts (ELA), math, and science, with ELA the clearest concern: 19% of students were proficient, compared with 46% statewide.
Math is the school’s strongest subject compared with both the state and the Oberlin district, while ELA is weakest. School proficiency was 35% in math and 24% in science, versus 41% and 38% statewide; ELA was 19% versus 46%. The school was also below district results in all three subjects, by 6 points in math, 10 in science, and 16 in ELA. Grade results vary sharply: 10th-grade math reached 50%, 14 points above the state, while 7th-grade math was 18%, 20 points below. Eighth-grade science was another weak spot, at 17%, 22 points below the state. There are no other schools within 20 miles, so local school-to-school comparisons are unavailable.
Math has improved over the longer term, rising 15 percentage points from 2022–23 to 2025–26, although it fell from a 45% high in 2024–25 to 35%. Over the same period, ELA rose 6 points but its gap with the state widened by 7 points; science fell 4 points and its gap widened by 11. SchoolDigger placed the school at the 47th percentile, with 2 stars and a rank of 179 out of 340 in 2025–26, down from the 93rd percentile and 5 stars in 2021–22. Its low-socioeconomic-status subgroup percentile also dropped sharply, from 84 in 2024–25 to 41 in 2025–26, below the overall percentile of 47. The student-teacher ratio was 7.7 in 2024–25, down from 8.5, and the free/reduced-lunch rate was 56%. Other indicators offer some encouragement: the latest graduation rate was 95%, above the state’s 90%, and chronic absenteeism was 17%, slightly below the state’s 18%.
