Summary:

Zip code 61523 has one high school, Illinois Valley Central High School, serving grades 9–12 with 650 students. In 2025–2026, its graduation rate was 94%, compared with 90% statewide, and chronic absenteeism was 16%, compared with 24% statewide. The clearest overall academic pattern is that ELA and math results are generally near or above state rates, while science results are below the state in all three reported grade-and-test comparisons.

Because it is the only high school in the list, there is no local school-to-school top or bottom; the standout results are within this school. Its strongest comparison was grade 9 PreACT Secure ELA, with 73% proficient versus 62% statewide, or 12 percentage points higher. Its largest shortfall was grade 10 PreACT Secure science: 39% proficient versus 48% statewide, or 10 points lower. In grade 11 ACT results, ELA was 3 points below the state and math was 2 points below, while both grade 9 and grade 10 PreACT math results were above state rates.

Results moved in mixed directions from 2024–2025 to 2025–2026: grade 9 PreACT ELA rose 6 percentage points, while grade 10 PreACT science fell 6 points, widening its gap with the state. SchoolDigger gives the school 3 stars for 2025–2026, while its percentile ranking declined from the 71st percentile in 2023–2024 to the 60th in 2025–2026. Other context includes a 14.7 student–teacher ratio and 44% free/reduced lunch eligible in 2024–2025. The school’s relatively high graduation rate and lower-than-state absenteeism offer additional positive context, alongside the consistent science shortfall.
