Summary:
Zip code 60109 has one listed high school, Central High School, serving grades 9–12 and enrolling 1,575 students. The strongest headline for families is that Central’s 2025–26 proficiency rates were above Illinois’ in all nine reported subject-and-grade results, with advantages ranging from 14.7 to 24.8 percentage points.
There is no local top-to-bottom comparison because Central is the only school listed. Its results were consistently strong relative to the state: the largest lead was in grade 11 ELA, at 75% versus 50%, or 25 points; the smallest was in grade 9 ELA, at 76% versus 62%, or 15 points. Across the three grade-and-test comparisons in each subject, Central’s average advantage was about 20 points in ELA, math and science, showing a broadly balanced profile rather than one standout subject or an obvious relative weakness.
Scores changed in mixed directions: Central rose in four of nine matched comparisons and fell in five. All three grade 11 ACT results improved, including science by 8 points, while grade 10 science fell 9 points and grade 9 ELA fell 7. Across the nine comparisons, the average lead over the state narrowed by about 1 point, from 21 to 20.
