Summary:
Zip code 60151 has one listed elementary school, Lily Lake Grade School, serving kindergarten through grade 5 with 275 students. In 2025–2026, its all-grades proficiency was 75% in English language arts (ELA) and 65% in math; fifth-grade science proficiency was 76%. Those results were above Illinois rates by 19 points in ELA, 25 points in math, and 28 points in science. The most important takeaway is that the school scored above the state in every reported subject and grade comparison.
There is no meaningful top-versus-bottom school comparison: Lily Lake is the only school in the list. Its strongest state-relative result was fifth-grade science, while math had a larger state advantage than ELA despite a lower school proficiency rate. Grade-level scores show some variation: math ranged from 75% in grade 3 to 57% in grade 5, and even the lower result was 21 points above the state. The district comparison offers another perspective: Lily Lake’s all-grades ELA result was 5 points below Central CUSD 301, although its ELA results were higher than the district’s in each reported grade. Its all-grades math result was 2 points above the district’s.
Results increased in all three subject comparisons from 2024–2025 to 2025–2026, but ELA and math changed by less than a point at the school, and their advantages over Illinois narrowed by 3 points and 1 point, respectively. Fifth-grade science rose by 8 points, and its state-relative advantage widened by 1 point. SchoolDigger ranked Lily Lake 234th of 1,737 schools, at the 87th percentile, in 2025–2026; its percentile placement was broadly steady at 88th in 2024–2025 and 86th in 2023–2024. Other context includes a 14.8 student-teacher ratio (SY 2024–2025) and 24% free/reduced lunch eligible (SY 2024–2025). With only one school listed, the data cannot show how these context figures compare with nearby schools.
