In fourth-grade ELA, results range from 84% at Chelsea Elementary School to 55% at Peotone Intermediate Center, a 29-point spread. The most important takeaway is that school results vary substantially, so the experience depends on the school and grade.

Chelsea and Hickory Creek Middle School are the clearest achievement standouts in their comparable grade groups: Chelsea leads the reported elementary comparisons in grades 3–5, while Hickory Creek scores higher than Summit Hill Junior High School in every supplied seventh- and eighth-grade subject comparison. Hickory’s seventh-grade math result is 83%, compared with 48% at Summit Hill, a 35-point difference. Peotone’s fourth-grade ELA result is the lowest in the matched elementary comparisons and just below the state’s 56%; its math result is 49%, while Chelsea’s is 78%. At high school, Lincoln-Way East High School is well above the state in all reported ACT subjects, including a 32-point advantage in math.

Year-to-year results are mixed: school scores rose in some comparisons, but state results often rose faster, narrowing schools’ advantages. Lincoln-Way East’s ACT gaps widened by 2 to 5 points, while its tenth-grade PreACT scores fell. SchoolDigger rankings also declined from 2023–24 to 2025–26 at several schools, including Summit Hill, from the 90th to the 72nd percentile, and Indian Trail, from the 97th to the 84th; Hickory Creek remained high, moving from the 99th to the 98th. Student–teacher ratios range from 9.5 at Dr Julian Rogus School to 18.1 at Lincoln-Way East.
