Summary:
Rochelle CCSD 231 has three elementary schools serving kindergarten through grade 5: Lincoln serves kindergarten–grade 1, Central serves grades 2–3, and Tilton serves grades 4–5. Chronic absenteeism is lower at all three schools than the state rate: 14% at Central, 15% at Tilton, and 17% at Lincoln, compared with 24% statewide. The most important finding is the sharp split in reported math results: Central was close to the state, while Tilton was well below it.
Among the schools with 2025–2026 IAR results, Central stands out and Tilton has the weakest reported results. Central had 38% proficiency in both ELA and math, while Tilton had 31% in ELA and 16% in math; Central’s leads were 6 points in ELA and 23 points in math. Central’s math result was 1 point below the 40% state result, while Tilton’s was 24 points below; their ELA results were 19 and 25 points below the state, respectively. At grade level, Tilton’s fifth-grade math proficiency was 11%, 26 points below the state benchmark. Lincoln has no supplied test-score entries, and the schools serve different grade bands, so their all-grades results are not fully like-for-like comparisons.
Results improved at Central in both subjects, while Tilton’s math result fell. From 2024–2025 to 2025–2026, Central rose 8 points in ELA and 8 in math; Tilton rose 3 points in ELA but declined 4 points in math. Tilton’s fifth-grade science result increased 2 points, though it remained 18 points below the state. As context—not an explanation for score differences—2024–2025 free/reduced lunch eligible shares were 57% at Central, 52% at Tilton, and 54% at Lincoln; student-teacher ratios ranged from 13.7 at Tilton to 14.3 at the other two schools. SchoolDigger placed Tilton at the 6th percentile in 2025–2026, down from the 22nd percentile the year before; separately, SchoolDigger ranked the district 703rd of 738 in Illinois, at the 5th percentile, with 0 stars.
