Summary:
Zip code 60521 has six schools—four elementary schools, one middle school and one high school—with strong reported results across the area. In 2025–2026, all four elementary schools scored above state results in both all-grades IAR subjects; their average proficiency was 91% in ELA and 90% in math, compared with 56% and 40% statewide. The clearest overall finding is that all four elementary schools performed well above state results, with Oak Elementary School leading the shared comparison.
Oak had the highest elementary all-grades scores, at 94% in both ELA and math—4 and 6 percentage points above the other three schools’ averages. Madison Elementary School was lowest in all-grades ELA at 89%, while The Lane Elementary School was lowest in math at 87%; both still exceeded state results. Grade-level results add important exceptions: in grade 5 math, Lane scored 72% and Oak 95%, a 23-point gap. Madison also stood out for grade 3 ELA at 75%, well below the other elementary schools’ 90%–92%. Hinsdale Middle School exceeded state results by 29 points in ELA and 37 in math; Hinsdale Central High School was 38, 46 and 35 points above the state in grade 11 ACT ELA, math and science, respectively.
Elementary all-grades averages slipped from 2024–2025 to 2025–2026: ELA fell from 92% to 91%, and math from 91% to 90%; because state results rose, the average school–state gaps narrowed. Grade 5 science improved from an 85% average to 90%. Middle- and high-school trends varied by subject, so recent results do not point to one uniform area-wide trend. SchoolDigger ranks the four elementary schools in the 99th or 100th statewide percentile, Hinsdale Middle in the 95th and Hinsdale Central in the 98th. Elementary student–teacher ratios range from 11.3 to 13.7. All schools with reported income data use the free/reduced lunch eligible measure for sy 2021–2022: 0.7%–1.2% at the elementary schools, 2.7% at the middle school and 5.7% at the high school. These figures provide context, not an explanation of test results.
