Summary:
The Bradley Bourbonnais CHSD 307 list includes one high school serving grades 9–12: Bradley-Bourbonnais C High School, with 1,914 students. Because it is the only school listed, parents cannot compare it with other schools in the area; the clearest comparisons are with state results and the school’s own results over time. The most important finding is that in 2025–2026, the school scored above the state in seven of nine matched subject-and-grade comparisons, up from four of nine the previous year.
Bradley-Bourbonnais C High School is both the highest- and lowest-ranked school in this one-school list, which does not indicate how it compares with other local schools. Its strongest latest comparison was grade 10 science, where 56% met proficiency compared with 48% statewide, a 7-point advantage. The only result below the state was grade 10 mathematics: 34% compared with 36%, a 2-point gap. Across all nine comparisons, its average advantage was about 2 points in 2025–2026, compared with about 1 point in 2024–2025.
Results improved overall, but not in every subject: all three grade 11 ACT results rose, by 4 to 5 points, and shifted from below to above state results. In contrast, grade 9 science fell 12 points, from 61% to 49%; it remained above the state, but its advantage narrowed from 10 points to 2. SchoolDigger placed the school at the 66th percentile in 2025–2026, after the 70th percentile in 2024–2025 and 57th in 2023–2024. Other indicators are mixed: graduation was 93%, 4 points above the state, while chronic absenteeism was 29%, 6 points higher; dropout was 2%, 1 point below the state. The student-teacher ratio was 15.3, and 50% of students were free/reduced lunch eligible in 2024–2025; these are context, not evidence of what drives results.
