Summary:
Morrison, Illinois, has four schools serving prekindergarten through grade 12: Northside School (PK–2), Southside School (3–5), Morrison Junior High School (6–8), and Morrison High School (9–12). The results vary considerably across grades and subjects: for example, junior high ELA results exceed state results at every tested grade, while Southside ELA results fall below the state in grades 3–5. Northside has no test scores in the supplied records. The most important finding is that no single school-level headline captures this uneven academic picture.
Morrison Junior High School stands out in ELA, with proficiency above the state by 16 points in grade 6, 10 in grade 7, and 3 in grade 8. Morrison High School also stands out on 11th-grade ACT results: 12 points above the state in ELA, 3 in math, and 10 in science. By contrast, Southside School is below the state in ELA in all three grades, including 24 points in grade 5; its grade 5 science result is a brighter spot, 4 points above the state. High school results also differ by grade: grade 10 PreACT proficiency is below the state in all three subjects, including 17 points in science.
Recent all-grades IAR changes diverge: junior high ELA rose 24 points and math 3 points from 2024–25 to 2025–26, while Southside ELA fell 9 points and math 17. SchoolDigger’s percentile rank for Southside fell from 66 in 2023–24 to 29 in 2025–26; junior high ended at 57, down 11 points over that period, while the high school stayed nearly level at 59. Attendance provides another contrast: Southside had the lowest chronic absenteeism, 7%, while the high school had the highest, 17%; both were below the state’s 24%. For 2024–25, free/reduced lunch eligible shares ranged from 34% at the high school to 45% at Northside. These figures describe different aspects of the schools and do not by themselves explain academic results.
