Summary:
Carterville CUSD 5 serves 2,162 students across four schools, from kindergarten through grade 12: Tri-C Elementary School, Carterville Intermediate School, Carterville Junior High School, and Carterville High School. The clearest overall signal is that every school’s reported 2025–2026 test results were above the state result for the same grade and subject.
Carterville Intermediate School stands out most in grades 4–6: its ELA results were 23–30 points above the state, math was 37–43 points above, and grade 5 science was 28 points above. Tri-C Elementary School also had a strong grade 3 showing, 28 points above the state in ELA and 22 in math. Carterville Junior High School had the narrowest advantage in math—11–16 points—though its ELA results were 17–18 points above the state. Carterville High School was above the state in all three grade 11 ACT subjects, by 15 points in ELA, 16 in math, and 6 in science. Because the schools serve different grades, their scores do not support a fair all-school ranking.
Recent results show gains and setbacks rather than one uniform trend. The three schools reporting IAR results in both years improved in ELA, with their margins over the state widening; math margins widened at Intermediate but narrowed slightly at Tri-C and Junior High. At High, grade 10 PreACT results rose in all subjects, while grade 9 results fell; grade 11 ACT ELA and science also dropped 12 and 11 points, respectively, though all three ACT subjects remained above the state. High’s graduation rate was 100%, versus 90% statewide. SchoolDigger ranks the district 94th of 738 with four stars; its latest listed school ranks are High 100th of 620 and Junior High 274th of 1,126. Student–teacher ratios range from 14.0 to 17.0. All four schools report free/reduced lunch eligible for 2024–2025, ranging from 43% at High to 47% at Intermediate.
