(USA Today) — Colleges are tacking on mandatory student fees at a time when state funding is dwindling and public universities are trying to hold the line on tuition. Indiana University-Bloomington is adding a $180 “temporary repair and maintenance fee” this fall; next year it doubles. Freshmen and transfer students this fall at Southern Illinois University in Carbondale will be charged a one-time $150 “matriculation fee” for orientation costs. Students at Georgia’s public universities will pay 3% more in tuition, but with fees the increase jumps to an average 9% more than last year. The rise is driven primarily by a “special institutional fee” that will cost as much as $1,088 next year for some students. For Georgia Tech freshmen, all fees total $2,370 — about a quarter of the total charge, $9,652.
