Illinois' guaranteed-tuition law making college less affordable

A study by University of Illinois experts found that Illinois' guaranteed-tuition law has led to a 26-30% increase in annual tuition rates and a 6-7% increase in four-year tuition rates compared to trends at other institutions. This trend suggests that the policy may not be effective in promoting affordability.
