Summary:
ZIP code 60550 has one listed high school, Indian Creek High School, which serves grades 9–12 and enrolls 268 students. The clearest pattern is a strong grade 9 compared with the state, followed by results below the state in grades 10 and 11.
Because there is only one school in the ZIP code, families cannot compare it with another local high school in this dataset; against Illinois results, grade 9 is the school’s strongest area. In 2025–2026, its proficiency was higher than the state by 12 percentage points in English language arts, 9 in math, and 11 in science. Grade 10 was below the state by 2 points in English, 6 in math, and 7 in science. Grade 11 was further below in every subject: 9 points in English, 7 in math, and 10 in science. Other measures offer some positive context: graduation was 91%, compared with 90% statewide, while chronic absenteeism was 19%, below the state’s 24% but above the Indian Creek CUSD 425 rate of 13%.
Results generally improved from 2024–2025 to 2025–2026: eight of nine grade-and-subject scores rose, with grade 11 science the exception, falling 1 point. Across the nine comparisons, the average gap from the state improved by about 8 points, though grade 11 remained below state levels in all three subjects. SchoolDigger’s ranking also moved from 381 of 698 schools (45th percentile, 2 stars) to 262 of 620 (58th percentile, 3 stars); the number of schools ranked changed. The school reported a student–teacher ratio of 12.9 in 2024–2025 and 38% free/reduced lunch eligible in that school year. These figures describe the school, but the single-school list does not show how it compares with similar schools.
