Summary:
Zip code 60561 has seven public schools—four elementary, two middle, and one high school—serving students from elementary through high school across several districts. Proficiency results are available for five schools; results were not supplied for Mark DeLay School or Elizabeth Ide Elementary School. Most importantly, the four schools with all-grades IAR results average above Illinois in both ELA and math, but the differences among local schools—especially in math—are substantial.
Concord Elementary School leads the all-grades math comparison at 70% proficient, 31 points above the state’s 40% and 25 points above the lowest result, Eisenhower Junior High School at 46%. In ELA, Cass Junior High School leads at 76%, compared with 59% at Eisenhower and 56% statewide. The gap between the highest and lowest school is 25 points in math and 17 in ELA. Hinsdale South High School, the area’s only high school, is also above Illinois in all three reported ACT subjects, by 14–15 points.
Recent changes are mixed: the four-school IAR ELA average rose 3 points from 2024–2025 to 2025–2026, while math rose less than 1 point. Fifth-grade science gains at Lace Elementary School and Cass were larger—28 and 23 points, respectively, compared with 7 points statewide. SchoolDigger ranking percentiles fell most at Eisenhower, from 70 to 54 over three years, and Lace, from 79 to 68; these rankings are separate from proficiency scores. Student-teacher ratios range from 9.4 at Eisenhower to 17 at Elizabeth Ide, with no simple relationship to results. For context, the reported free/reduced lunch eligible figures for six schools are for sy 2024–2025; Hinsdale South’s 19% figure is for sy 2021–2022, so it is not a like-year comparison.
