LARAMIE, Wyo. (AP) — The University of Wyoming Board of Trustees has approved raising tuition and fees over the next two years.

Under the plan approved Friday afternoon, tuition paid by resident students at the state's only four-year public university will increase 2 percent in each of the next two years while nonresident students will pay 4.5 percent more in each of 2013 and 2014.

For a resident undergraduate student, tuition that costs $104 per credit hour this year would increase to $108 per credit hour by 2014. Nonresident per credit hour tuition will go from $576 to $629.

Mandatory student fees will increase from just over $1,000 a year to about $1,164.

Even with the increase, a survey says UW has the lowest tuition and fees of all U.S. public doctoral institutions.
