Summary:
The two middle schools in O Fallon CCSD 90 are Fulton Junior High School and Amelia V Carriel Junior High; both serve grades 6–8 and enroll nearly the same number of students, 667 and 664. In 2025–2026, both schools scored above the state in all three reported comparisons: all-grades English language arts (ELA) and math, and eighth-grade science. The clearest finding is that Fulton leads Carriel in every reported subject and grade.
Fulton is the academic standout, while Carriel is lower in each all-grades or grade-matched comparison. In 2025–2026, Fulton’s proficiency was 80% in ELA, 61% in math, and 77% in eighth-grade science, compared with Carriel’s 71%, 48%, and 69%. Those school-to-school gaps were 9, 13, and 7 percentage points, respectively. Carriel still exceeded state results by 15 points in ELA, 9 in math, and 17 in science; Fulton’s science result was 25 points above the state. The two-school average was 21 points above the state in science, 19 in ELA, and 15 in math. Carriel’s results were below the district in all three comparisons, while Fulton’s were above it.
Scores increased at both schools from 2024–2025 to 2025–2026, especially in science and math, though ELA gains were small. Fulton rose by 1 point in ELA, 4 in math, and 5 in science; Carriel gained less than 1 point in ELA, 3 in math, and 9 in science. SchoolDigger’s ranking percentiles fell over the same period despite the score increases: Fulton went from the 92nd to the 89th percentile, and Carriel from the 82nd to the 73rd. As context, Fulton’s student-teacher ratio is 18.5, compared with Carriel’s 17.9; their 2024–2025 free/reduced lunch eligible shares were 19% and 27%, respectively. Chronic absenteeism in 2025–2026 was 8% at Fulton and 12% at Carriel. These observations do not explain why scores differ.
