59^th

SchoolDigger Rank ?

of 1,737 Illinois Elementary Schools

Better than 97% of Illinois elementary schools

Summary

Cossitt Ave Elementary School serves 472 students in kindergarten through grade 6 in La Grange, as part of La Grange School District 102. The central takeaway is that its 2025–2026 proficiency results in English language arts (ELA) and math were well above both district and state results.

Cossitt was third among nine nearby schools with reported all-grade results in both ELA and math, and it led the same-district K–6 schools with reported scores. ELA proficiency was 89%—11 points above the district and 33 above the state—while math was 80%, 13 points above the district and 40 above the state. Grade 5 science was another strength compared with the state: 74% proficient, 27 points higher, and 8 points above the nearby-school average; however, Cossitt ranked fourth among nine nearby schools. Results vary by grade: grade 5 ELA was 80%, below the school’s 89% all-grade result, while grade 3 ELA reached 93%. In math, grade 3 reached 90%, 13 points above grade 4.

Both tested subjects have improved since 2023–2024: ELA rose 15 percentage points to 89%, and math rose 13 points to 80%. The advantage over the state remained broadly stable rather than steadily increasing. SchoolDigger ranked Cossitt 59th of 1,737 Illinois schools in 2025–2026, in the 97th percentile with five stars; the district ranked 143rd of 738, in the 81st percentile with four stars. The student-teacher ratio was 11.5 in 2024–2025, nearly matching the nearby average. Free/reduced lunch eligible students made up 3% in 2023–2024, down from 5% in 2021–2022. One result to ask about is SchoolDigger’s Disabled Students standing: the school was in the 71st percentile in 2025–2026, compared with its overall 97th percentile and the group’s 96th percentile the prior year; caution is warranted because the latest comparison pool included just 21 schools, versus 1,049 the year before.
