Tuition will increase by $420 for Illinois residents and $750 for non-residents, bringing tuition totals to $8,835 for in-state students and nearly $21,790 for out-of-state students. However, the tuition bills for existing students will remain unchanged.
Students from Missouri, Iowa and five other nearby states pay the same rate as their Illinois classmates.
Board Chairman Randal Thomas says school officials don't want to raise tuition, but it must be done since Gov. Bruce Rauner has proposed cutting state university funding by 31.5% next year.
The tuition hike is expected to generate an additional $162,000 in revenue for the school.
