Best Public Schools in South Elgin, IL

South Elgin, Illinois, has six schools serving elementary through high school: four elementary schools, one middle school and one high school, with five in U-46 and Corron Elementary School in St Charles CUSD 303. The data includes mostly 2025–2026 results and shows substantial variation between schools. The most important finding is that the area’s elementary results are uneven, largely because Corron’s scores are far higher than those of the other schools.

Corron stands out in matched grade 3–5 averages, scoring 84% in ELA and 82% in math, compared with 53% and 44% at the next-highest school, Clinton Elementary School. Corron also led grade-5 science at 68%, versus 36% at Willard Elementary School and 48% statewide. Willard had the lowest grade-3–5 averages, at 50% in ELA and 37% in math, while Fox Meadow Elementary School was lowest in grade-3 ELA and grade-6 math. The middle school, Kenyon Woods Middle School, was above state results in ELA and science but below in math. South Elgin High School was below state ACT results in all three reported subjects.

Recent elementary averages improved overall, but not at every school: all-grades ELA rose from 56% to 61% and math from 45% to 50% between 2024–2025 and 2025–2026, while Fox Meadow’s ELA result fell 6 points and Clinton’s rose 8. SchoolDigger ranked Corron in the 95th percentile statewide; the other schools ranged from the 37th to 51st percentiles, and most had lower percentile positions than in 2023–2024. Context also differs: in 2024–2025, free/reduced lunch eligible measures ranged from 15% at Corron to 55% at Willard. Elementary student-teacher ratios ranged from 14.3 at Corron to 20.6 at Clinton; these figures provide context but do not explain test results.
