Summary:
Bismarck, Illinois, has three listed schools serving prekindergarten through grade 12: Bismarck-Henning Elementary School (PK–4), Bismarck-Henning Junior High School (5–8), and Bismarck-Henning Rossville-Alvin Cooperative High School 1 (9–12). In 2025–2026, the two schools with results averaged 69% proficiency in English language arts (ELA), compared with 56% statewide; their math average was 39.8%, essentially even with the state’s 39.6%. The clearest overall finding is that the area’s results were notably stronger in ELA than in math relative to the state.
Bismarck-Henning Elementary School had the higher latest all-grades scores in both subjects: 76% in ELA versus 62% at junior high, a 14-point lead, and 53% in math versus 26%, a 27-point lead. Both schools were above the state in ELA, but junior high math was 13 points below it; elementary math was 14 points above. Results also vary by grade: elementary grade 3 was 31 points above the state in ELA and 27 points above in math, while its grade 4 math score was 7 points below. At junior high, grade 6 was above the state in both ELA and math, by 19 and 6 points, respectively.
Both schools improved over the two years of reported all-grades scores, with the largest gains in elementary ELA. From 2024–2025 to 2025–2026, that score rose 42 points, while junior high ELA rose 5 points; the two-school ELA average gained 24 points, compared with 3 statewide. The math average gained 8 points, compared with 1 statewide. SchoolDigger’s percentile rose from 42 to 74 for elementary between 2023–2024 and 2025–2026, while junior high moved from 51 to 52. The schools had similar reported context measures in 2024–2025: enrollments of 309 and 246, student-teacher ratios of 13.4 and 13.6, and free/reduced lunch eligible shares of 41% and 44%; these figures are context, not an explanation for score differences.
