Summary:

Lyons School District 103 includes six schools—five elementary schools and one middle school—with 2,042 students and enrollments ranging from 228 to 659. The schools show meaningful differences, but none reaches the state’s all-grades proficiency results in either subject: in 2025–26, their average was 46% in English language arts (ELA) and 28% in math, compared with 56% and 40% statewide.

Costello School leads in ELA, with 54% proficient—10 points above the other schools’ average, though 2 points below the state. Edison Elementary School leads in math at 37%, 11 points above the other schools’ average and 2 points below the state. At the lower end, Home Elementary School has the lowest all-grades ELA result, 37%, while Washington Middle School has the lowest math result, 18%—12 points below the other schools’ average. Grade-level results add important detail: Costello exceeds the state in grade 3 ELA, while J W Robinson Junior Elementary School exceeds it in grade 4 ELA and grade 5 math.

Recent results point in different directions: the schools’ average ELA proficiency fell 1 point from 2024–25 to 2025–26 as the state result rose 3 points, widening the average gap from 6 to 10 points. Average math proficiency rose 2 points, and the gap to the state narrowed slightly, from 12.2 to 11.8 points. SchoolDigger’s percentile rankings also varied: Robinson gained 15 points from 2023–24 to 2025–26, while Home fell 28. The reported free/reduced lunch eligible measure for 2024–25 ranged from 72% to 87%; Robinson had the highest share, yet its ELA and math results were second-highest. Student-teacher ratios ranged from 8.5 to 11.1, and the results do not sort neatly by either measure.
