Summary:
ZIP code 60091 has seven schools—four elementary and three middle schools, with no high schools—and the reported results cover elementary and middle grades. In 2025–2026, the seven schools averaged 87% proficiency in English language arts (ELA) and 82% in math, compared with state results of 56% and 40%; the most important takeaway is that every school’s reported all-grades result was well above the state in both subjects.
McKenzie Elementary leads the elementary schools overall, with 92% in ELA and 90% in math; its math result is 9 points above the other schools’ average. Marie Murphy School leads the middle schools overall at 93% in ELA and 87% in math, and leads the available same-grade comparisons in grades 6–8. Not every grade-level leader is the same: Central Elementary has the highest grade 3 math result, at 95%. At the lower end, Harper Elementary is lowest among the elementary schools in both all-grades subjects (80% ELA and 76% math), while Wilmette Junior High School has the lowest middle-school all-grades math result, at 69%. Both remain above their respective state results.
Results generally rose from 2024–2025 to 2025–2026, but ELA gains lagged the state: the schools’ average rose about 1 point, compared with a 3-point state increase. Average math rose about 1 point, essentially matching the state’s gain. Science improved at all three schools with two-year results, including an 9-point rise at Highcrest Middle School and a 7-point rise at Marie Murphy. SchoolDigger’s listed percentile increased from 97 to 99 for McKenzie and from 96 to 98 for Marie Murphy, while it declined from 95 to 93 for Harper and from 96 to 93 for Wilmette Junior High. As context, 2021–2022 free/reduced lunch eligible shares ranged from 1% to 7% at the elementary schools and from 3% to 8% at the middle schools; 2024–2025 student-teacher ratios ranged from 9.4 at Romona and Marie Murphy to 13.5 at McKenzie. These figures describe different aspects of the schools and do not by themselves explain results.
