ISU trustees approved a 13.5 percent tuition and fee increase for new in-state students that will boost the average annual cost by about $920 a year. The rate will not change during their four years of school because of the state's guaranteed tuition law.

ISU President Al Bowman says the increase is needed because state funding for ISU has declined by more than $60 million since 2002.

Trustees also boosted room-and-board rates by more than seven percent for incoming students next fall.

Combined, new on-campus students will pay nearly $14,000 to attend ISU next fall, about $1,400 more than this year's incoming students.
