The most important finding is that Lisle is ahead of the state across all its reported subject and grade results.
There is no second school in this area’s list to compare at the top or bottom, so Lisle is the only school-level option represented. Its strongest grade-subject result relative to the state was 7th-grade math: 62% proficient, 22 percentage points above the state result. Eighth-grade math was a comparatively weaker spot, at 48% proficient and 13 points above the state; its advantage was still positive, but smaller than in other grade-subject comparisons. Chronic absenteeism was also lower than the state rate in 2025–2026: 15% at Lisle versus 24% statewide, and 17% in the district.
