Summary:
Eureka CUD 140 has one middle school, Eureka Middle School, serving grades 5–8 and enrolling 436 students. Its 2025–2026 proficiency rates were above state rates in every listed subject and grade: all-grades ELA was 78% versus 56% statewide, and math was 58% versus 40%; grade 5 and grade 8 science were 78% and 71%, compared with 48% and 52% statewide. The most important finding is that the school outperformed the state in every reported 2025–2026 subject and grade.
Eureka Middle School is the only school in the list, so there is no meaningful local top-versus-bottom comparison. Its clearest relative strength is ELA: the school’s advantage over the state was 22 percentage points in all-grades ELA, compared with 18 points in math; grade 5 science had the largest listed advantage, at 30 points. The school’s ELA rate was also 1 point above the district, while its math rate was 3 points below it. SchoolDigger gives the school 4 stars and ranks it 161st of 1,126 Illinois schools, at the 86th percentile.
Scores improved from 2024–2025 to 2025–2026, but the school’s leads shifted: ELA rose by 1 point while the state rose by 3, narrowing the ELA advantage by 3 points; math rose by 4 points while the state rose by 1, widening the math advantage by 3 points. Science scores rose in both tested grades: the grade 5 state advantage grew by 1 point, while the grade 8 advantage narrowed by 1 point. SchoolDigger’s percentile ranking moved from the 91st percentile in 2023–2024 to the 89th in 2024–2025 and 86th in 2025–2026, and its rating changed from 5 stars to 4. Other context: the 2024–2025 student-teacher ratio was 15:1, and 26% of students were free/reduced lunch eligible; in 2025–2026, chronic absenteeism was 6%, versus 11% districtwide and 24% statewide. Because this area has just one middle school, these figures cannot show how school characteristics compare with results across local schools.
