INDIANAPOLIS (AP) — Indiana University says its Board of Trustees has approved freezing undergraduate tuition rates for the next two years for Indiana residents attending the main campus in Bloomington.

The school says the trustees voted Wednesday to approve the recommended freeze that IU President Michael McRobbie presented two weeks ago.

The trustees also approved a 1.5 percent increases for out-of-state students on the Bloomington campus for the next two years. Tuition increases at Indiana University-Purdue University Indianapolis and IU’s five regional campuses will increase by an average of 1.65 percent.

Graduate school tuition increases for Indiana residents will vary by school but will average about 2 percent and won’t exceed 3 percent. Nonresident graduate school tuition would increase just under 3 percent on average.
