Summary:
Naperville CUSD 203 has 14 elementary schools: 13 serve kindergarten through fifth grade, and Naper serves kindergarten through fourth grade. In 2025–26, the schools averaged 83% in all-grades English language arts (ELA), 75% in math, and 75% in fifth-grade science, each above the state averages of 56%, 40%, and 48%, respectively. The biggest school-to-state advantage was in math, at 35 percentage points. Most importantly, every school was above the state result, but results varied considerably from one local school to another: the spread was 19 points in ELA, 28 in math, and 32 in science.
Meadow Glens led ELA at 93% and fifth-grade science at 97%, and placed second in math at 87%. Highlands led math at 89% and was close behind in ELA at 93%; Prairie was strong across all three subjects, with 92% ELA, 84% math, and 83% science. At the lower end, Kingsley had the lowest ELA and math results, at 75% and 61%. Its math score was 15 points below the average for the other schools. Elmwood had the lowest science result, at 65%.
Recent changes were mixed: average ELA was nearly unchanged, math fell 2 points, and fifth-grade science was essentially flat. Ellsworth stood out for an 8-point ELA gain, while Kingsley’s math fell 13 points. SchoolDigger ranked Meadow Glens 14th, Highlands 15th, and Prairie 21st among Illinois elementary schools; Kingsley ranked 308th. School characteristics do not neatly predict results: for example, Mill Street’s free/reduced lunch eligible measure was 35% in 2024–25, the highest in the group, yet its ELA and math results were 84% and 72%, both above the area averages. By contrast, Kingsley’s measure was 16%, alongside the lowest math result. These figures offer context, not an explanation for school performance.
