Illinois State Board of Education (ISBE) records show that 58.5 percent of Wilmington High School's (WHS) 2015 graduating class enrolled in college within 12 months of graduation.
The 2015 state average for students in public schools was 70 percent.
For WHS, its college enrollment rate marks a decline since 2014, when 61 percent of its graduates chose post-secondary education.
The data, collected by the National Student Clearinghouse, includes two- and four-year colleges.
Enrollment at WHS in 2015 was 480; 122 (25.42 percent) were seniors.
Also according to ISBE, 46 percent of WHS seniors were "college ready" in 2015, versus an average of 46 percent statewide.
All students who score a 21 on the ACT qualify as "college ready."
