(SOUTH FLORIDA SUN-SENTINEL) Many Florida families have been paying up to 25 percent of median income for public in-state college costs — out of reach for some middle-class parents who have taken recent pay cuts or lost jobs, according to a new study.

Some South Florida families are paying even more — plunking down what amounts to about a third of the median income for Floridians for students to attend Florida International University orFlorida Atlantic University, according to the study co-written by the Research Institute on Social and Economic Policy at FIU.

With 15 percent tuition hikes starting this fall, FAU students will pay more than $17,000 a year, including room and board. FIU students face similar costs.
