The 2015 state average for students in public schools was 70 percent.
For MHS, its college enrollment rate marks a decline since 2014, when 62 percent of its graduates chose post-secondary education.
The data, collected by the National Student Clearinghouse, includes two- and four-year colleges.
Enrollment at MHS in 2015 was 590; 128 (21.7 percent) were seniors.
Also according to ISBE, 33.9 percent of MHS seniors were "college ready" in 2015, versus an average of 46 percent statewide.
