Summary:
Illini West H S District 307 has one high school, Illini West High School, serving grades 9–12 with 349 students; its clearest academic pattern is ELA near the Illinois average, while math and science results are substantially lower.
Because it is the only school in the list, Illini West is both the highest and lowest among the listed schools; that is not a comparison with other area schools. Against Illinois in 2025–2026, its average across the three reported ELA results was effectively even with the state, at 55% for each. Its math average was 28% versus 39% statewide, a 12-point shortfall, and its science average was 37% versus 48%, an 11-point gap. Ninth-grade ELA stands out positively: 70% were proficient, 9 points above the state. By contrast, 10th-grade math and science were each 15 points below Illinois. Other outcomes are mixed: graduation was 82% versus 90% statewide, dropout was 6% versus 2%, and chronic absenteeism was lower at 21% versus 24%.
Results improved relative to the state on average, though not in every subject. From 2024–2025 to 2025–2026, the average school-versus-state gap across the matched results narrowed from 12 points below to 8 points below—a 4-point improvement. Ninth-grade ELA rose 11 points, moving from 3 points below the state to 9 above it; meanwhile, 10th-grade science fell 7 points and 11th-grade ACT math fell 2. SchoolDigger’s school percentile ranking dropped from 54 in 2023–2024 to 36 in 2024–2025, then edged up to 38 in 2025–2026. For context, in 2024–2025 the school had a student–teacher ratio of 15 and 54% of students were free/reduced lunch eligible; these figures describe the school, not what drives its results.
