Summary:
Wesclin CUSD 3 has four schools—two elementary schools, one middle school and one high school—serving students from elementary through high school. In 2025–2026, all four had lower chronic absenteeism than the statewide rate: Trenton Elementary School was at 5%, New Baden Elementary School at 10%, Wesclin Middle School at 10%, and Wesclin Senior High School at 16%, compared with 24% statewide. The clearest overall strength is that attendance at every school was better than the state comparison.
The elementary schools each lead in a different third-grade subject: Trenton reached 80% proficient in ELA, 11 points above New Baden’s 69%, while New Baden reached 76% in math, 4 points above Trenton’s 72%. Both were well above state results of 48% in ELA and 49% in math. Wesclin Middle was above the state in every reported grade and subject; its strongest comparisons were grade 4 math, 77% versus 42% statewide, and grade 7 ELA, 82% versus 58%. Its smallest edge was grade 8 ELA, 64% versus 63%. The high school was above the state in eight of nine reported results. The exception was grade 10 ELA, where it scored 50% versus 54% statewide.
Recent changes were mixed: from 2024–2025 to 2025–2026, Trenton improved 17 points in ELA and 5 in math, while New Baden declined 2 points in ELA and 4 in math. Wesclin Middle’s all-grades results rose 4 points in ELA and 8 in math; high-school trends varied by grade and subject, including a 8-point drop in grade 10 ELA and a 14-point rise in grade 9 math. SchoolDigger ranks the district 217th of 738, in the 71st percentile, with four stars; its ranking histories place Wesclin Middle in the 71st percentile and Wesclin Senior High in the 70th. As context, 2024–2025 free/reduced lunch eligible shares ranged from 34% at the high school to 41% at New Baden; elementary student-teacher ratios were 14.7 at Trenton and 14.4 at New Baden. These figures do not align with a simple school-by-school achievement order.
