Summary:
ZIP code 60532 has four schools serving pre-K through grade 12: one elementary school, two junior highs and one high school, with 2,499 students enrolled. The schools report different assessments across grade levels, so their results are most useful for comparing schools serving similar grades. Most importantly, all four schools scored above state results in the subjects and grades reported for 2025–2026, but the middle-school results—especially in math—show a substantial gap between local schools.
Kennedy Junior High School stands out among the middle schools, leading Lisle Junior High School by 12 percentage points in all-grades ELA (90% versus 78%) and 27 points in math (82% versus 54%). Lisle Junior High has the weaker middle-school math result, though it remains above the state’s 40%. Lisle Elementary School, the only elementary school in the list, also exceeded state proficiency: its results were 71% in ELA, 63% in math and 74% in fifth-grade science. Lisle High School was above the state in all three grade-11 ACT subjects and had a 95% graduation rate, compared with 90% statewide. One counterpoint is attendance: chronic absenteeism at the high school was 22%, above the Lisle district’s 17%, though below the state’s 24%.
Recent trends are mixed. Lisle High’s ACT proficiency fell by 17 percentage points in ELA, 9 in math and 19 in science from 2024–2025 to 2025–2026, while its PreACT results varied by grade and subject. SchoolDigger’s percentile rankings from 2023–2024 to 2025–2026 slipped from 99th to 98th for Kennedy, 88th to 82nd for Lisle Elementary and 89th to 81st for Lisle Junior High; Lisle High rose from 89th to 91st. School characteristics offer context, not an explanation for these results: in 2024–2025, free/reduced lunch eligible students made up 11% at Kennedy and 33% at Lisle Junior High, while student–teacher ratios were 14.1 and 10.7, respectively.
