Summary
West Carroll High School in Mount Carroll, Illinois, serves grades 9–12 and enrolls 245 students. English language arts (ELA) is its relative academic strength, but it still trails the state; mathematics and science are larger concerns. In 2025–2026, 11th-grade ACT proficiency was 41% in ELA, 21% in math and 26% in science, with state gaps of 9, 19 and 22 percentage points, respectively. Most importantly, the school was below Illinois in every reported subject-and-grade comparison.
Compared with nearby schools, West Carroll’s test results are generally near the bottom: it had the lowest reported 11th-grade ACT science result and ninth-grade PreACT math result, and its 11th-grade ACT ELA result was second-lowest. There is a notable positive beyond test scores: its 2025–2026 graduation rate was 93%, above Illinois’ 90% and equal to the rate for West Carroll CUSD 314; it ranked third among the six nearby schools. Attendance is a greater concern: chronic absenteeism was 30% at West Carroll, compared with 24% statewide and 20% in the district, the highest rate among the nearby schools.
Results over time are mixed: 11th-grade ACT ELA rose from 25% to 41% between 2024–2025 and 2025–2026, and ACT math rose from 11% to 21%, while ninth-grade PreACT math fell from 27% to 17%. SchoolDigger’s overall standing also declined, from the 54th percentile in 2021–2022 to the 21st in 2025–2026; its latest rating was 1 star, the lowest among nearby schools, and its rank was 490 of 620. Some subgroup standings were stronger: SchoolDigger placed students in its “Low Socio Economic Status Students” group at the 44th percentile in 2025–2026, compared with the school’s overall 21st, a measure of how the school serves that group relative to similar students statewide. The school’s student-teacher ratio was 12.6 in 2024–2025, the highest among nearby schools, and 49% of students were free/reduced lunch eligible that year, also the highest nearby share.
