Summary:
Alton CUSD 11 includes nine schools in Alton: seven elementary schools, one middle school and one high school, serving 5,259 students from kindergarten through grade 12. Four elementary schools serve only kindergarten through grade 2 and have no test scores in this data, so score comparisons cover the other three elementary schools, the middle school and the high school separately. The most important finding is that every reported 2025–2026 test result for these schools fell below its corresponding state benchmark.
East Elementary School led elementary ELA at 39.4%, just ahead of North Elementary School at 38.6%—a 1-point gap—and 8 points ahead of West Elementary School at 31.3%. North led in math, scoring 32% versus 30% at East and 25% at West, and in fifth-grade science, with 40% compared with East’s 36% and West’s 28%. West had the lowest results of the three in all three subjects. SchoolDigger’s statewide ranking percentiles were highest for North at 23 and lowest for West at 9; East was at 19, Alton Middle School at 10 and Alton High School at 20.
Results over time are mixed: North’s math score rose 6 points from 2024–2025 to 2025–2026, while fifth-grade science improved at all three tested elementary schools; their average rose from 22% to 35%, though it remained below the state result. Alton High’s grade 11 ACT scores fell in all three subjects, including an 8-point drop in science. Attendance is another concern: chronic absenteeism was 32% at Alton High and 36% at Lovejoy Elementary School, compared with 24% statewide; seven of nine schools were above that state rate. School context varies, too: in 2024–2025, free/reduced lunch eligible students made up 51% at North, 65% at East and 57% at West, while student-teacher ratios were 16.1, 12.9 and 13.2, respectively. These are useful context for comparing schools, not explanations for their results.
