Arcola CUSD 306

Arcola CUSD 306 serves the Arcola area with two schools: Arcola Elementary School, serving PK–6 with 410 students, and Arcola High School, serving grades 7–12 with 299 students. In 2025–26, both schools’ reported all-grades IAR results were below state results: Elementary scored 42% in ELA and 20% in math, while High School scored 39% in ELA and 18% in math. The clearest shared concern is math: the schools’ equal-weight average was 19%, compared with 40% statewide, a 21-point gap; the average ELA gap was 16 points.

Elementary has the higher reported all-grades IAR results, leading High School by 3 points in ELA and 2 points in math, though the schools serve different grades and this is not a like-grade comparison. Its standout grade-level result is sixth-grade ELA: 63% compared with 59% statewide, 4 points higher. The largest supplied gaps include Elementary third-grade math, 24% versus 49% statewide (25 points lower), and High School eighth-grade ELA, 41% versus 63% (22 points lower). High School has a separate bright spot: its graduation rate is 93%, 3 points above the state’s 90%.

Recent results are mixed: from 2024–25 to 2025–26, ELA rose 7 points at High School but fell 1 point at Elementary, while math fell 6 points at each school. SchoolDigger rates both schools at one star: Elementary is at the 21st percentile and High School at the 27th, down from 41 and 40, respectively, in 2024–25. Staffing and income context also differ: student–teacher ratios are 13:1 at Elementary and 11:1 at High School; in 2024–25, free/reduced lunch eligible students made up 46% and 57%, respectively. These figures describe different school contexts and do not explain the test results.
