The 2015 state average for students in public schools was 70 percent.
For RBHS, its college enrollment rate marks a decline since 2014, when 70 percent of its graduates chose post-secondary education.
The data, collected by the National Student Clearinghouse, includes two- and four-year colleges.
Enrollment at RBHS in 2015 was 417; 106 (25.4 percent) were seniors.
Also according to ISBE, 51.4 percent of RBHS 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."
