The Iowa Board of Regents is backing another tuition freeze for undergraduate students at the state's three public universities. The board of regents called for the freeze during a meeting Wednesday in Cedar Falls. The proposed tuition freeze is included in a $652 million request to the Legislature for funding in 2014. That's an increase of nearly $44 million from the current budget. If approved, it would be the first time since 1975 that the universities didn't increase tuition for two consecutive years. Tuition was last increased in the 2012-2013 school year, when it rose 3.75 percent.
