Summary:
The three schools in Central CUSD 4 serve kindergarten through grade 12: Chebanse Elementary serves K–4 with 343 students, John L. Nash Middle serves grades 5–8 with 278, and Central High serves grades 9–12 with 298, for 919 students total. The most important takeaway is that results vary sharply by grade and subject: grade 3 math at Chebanse was 66% proficient, while grade 10 PreACT math at Central High was 20%.
Nash Middle stands out in IAR English language arts (ELA), with 63% proficiency across its grades in 2025–2026, compared with 50% at Chebanse—a 13-point difference. Nash was 7 points above the state rate, while Chebanse was 6 points below. Chebanse’s grade 3 math was 17 points above the state, and Nash’s grade 5 science was 14 points above. The clearest low result was Central High’s grade 10 PreACT math, 16 points below the state. Grade 11 ACT results at Central High were stronger in ELA and science, 7 and 6 points above the state, but math was 4 points below. Because schools serve different grades and use different tests, these comparisons are descriptive rather than a fully grade-adjusted ranking.
Recent trends are mixed: Central High’s grade 11 ACT proficiency rose 8 points in ELA, 8 in math, and 12 in science from 2024–2025 to 2025–2026, while its grade 10 PreACT results fell 7, 15, and 5 points in those subjects. Nash’s all-grades IAR ELA and math rose 12 and 5 points; Chebanse’s fell 5 and 10. SchoolDigger’s 2025–2026 percentile rankings were 50 for Chebanse, 55 for Nash, and 52 for Central High; Chebanse had dropped from 72 the prior year.

Free/reduced lunch eligible rates in 2024–2025 were 49% at Chebanse, 41% at Nash, and 38% at Central High; these figures provide context, not an explanation for test results.
