Summary:
High schools in zip code 60901 are represented by one school, Kankakee High School, which serves grades 9–12 and has 1,360 students. Its 2025–26 results show a consistent academic challenge: all nine reported test results were below state proficiency, by 19 to 28 percentage points, with an average gap of 24 points. That across-the-board shortfall is the most important finding for families considering the area’s high school.
Within this one-school group, there is no local school-to-school leader or trailer. The strongest current result was ninth-grade PreACT Secure English language arts, at 40%, though that was still 22 points below the state’s 62%. The lowest was eleventh-grade ACT mathematics, at 12% versus 40% statewide, a 28-point gap. The largest gaps were 28 points in ACT science and tenth-grade PreACT English language arts. Other outcomes are mixed: graduation was 92%, 2 points above the state, while chronic absenteeism was 53% versus 24% statewide, and dropout was 4% versus 2%.
Results improved overall, but not in every area. Ninth-grade PreACT math rose from 12% to 23%, an 11-point increase, while the state rose from 38% to 42%; the gap narrowed from 26 to 19 points. Eight of nine comparable test gaps narrowed, and the school’s average across the nine results rose from 21% to 23%, while the state average shifted from 48% to 47%. Tenth-grade PreACT English language arts was an exception: the school result fell from 29% to 25%, and its gap widened from 27 to 28 points. SchoolDigger places the school at the 13th percentile and awards one star for 2025–26; its percentile was 14 in 2023–24 and 15 in 2024–25. For context, 87% of students were free/reduced lunch eligible in 2024–25, and the student-teacher ratio was 15.6 that year. Because there is only one school, families cannot compare local schools against one another using these figures.
