Summary:
Countryside, Illinois, has one listed school: Ideal Elementary School, serving kindergarten through grade 6 with 258 students, in La Grange School District 105 South. Its 2025–26 results show a clear subject-area contrast: ELA proficiency is above the state, while math is nearly level with it overall but varies sharply by grade. The most important finding is that ELA is Ideal’s clearest strength, with results above the state in every tested grade.
Since Ideal is the only school in the list, it is the highest- and lowest-ranked locally by default; that is not a meaningful school-to-school distinction. Against Illinois, Ideal’s 2025–26 all-grades ELA proficiency was 64% versus 56%, an 8-point advantage. Its all-grades math result was 39% versus 40% statewide, essentially level and less than a point below. The biggest concern is sixth-grade math: 26% were proficient, compared with 36% statewide, an 11-point gap. Grade 5 science was 43%, 5 points below the state’s 48%.
Results improved from 2024–25 to 2025–26 in all three reported subject comparisons. ELA rose 12 points at Ideal, compared with 3 points statewide; grade 5 science climbed 20 points, versus 7 statewide, though it remained below the state. Math increased 4 points, compared with 1 statewide. SchoolDigger rates Ideal three stars and ranks it 856th of 1,737 schools, at the 51st percentile; its percentile was nearly unchanged from 2024–25. For context, the school’s 2024–25 student–teacher ratio was 8.7, and 72% of students were free/reduced lunch eligible that school year. Chronic absenteeism in 2025–26 was 22%, below the state’s 24% but above the district’s 13%. With only one school listed, there is no meaningful local school-to-school comparison.
