Summary:
The two elementary schools in ZIP code 60457 serve 1,080 students across prekindergarten through grade 5: Glen Oaks Elementary School serves grades 2–5, and Dorn Elementary School serves prekindergarten–grade 1. Both are in North Palos School District 117, which SchoolDigger rates five stars and ranks 47th of 738 statewide. The most important finding is that Glen Oaks’ available test results are well above state proficiency in both subjects: 84% in ELA versus 56% statewide, and 75% in math versus 40%.
Glen Oaks stands out in the achievement data, while Dorn’s academic results cannot be placed above or below it because no test scores are supplied for Dorn. Glen Oaks’ advantage over the state is 27 percentage points in ELA and 35 points in math; its math result is also 1 point above the district, while its ELA result is 1 point below. Fifth-grade math is a particular strength: 75% proficient, compared with 36% statewide, a 39-point gap. In school context, Dorn has a higher student-teacher ratio—16.5 versus 12.7 at Glen Oaks—and higher 2025–2026 chronic absenteeism, 12% versus 7%; these are differences in context, not academic rankings.
Glen Oaks’ state-relative position improved in math and science but narrowed in ELA over the two years supplied. Its ELA proficiency stayed at 84% as the state rose from 53% to 56%, narrowing Glen Oaks’ lead by 3 points; its math rose from 71% to 75%, widening its lead by 3 points, and fifth-grade science rose from 54% to 64%, widening its lead by 4 points. SchoolDigger ranks Glen Oaks 133rd of 1,737 schools, at the 92nd percentile—up 39 rank positions from the prior year, with the same percentile. As additional context, in 2024–2025, 60% of Glen Oaks students and 67% of Dorn students were free/reduced lunch eligible, a 7-point difference; the schools also differ in grade span, so families may want to weigh these contextual measures alongside the available achievement results.
