DALLAS -- Gov. Rick Perry has formally pitched a four-year tuition freeze for incoming college freshmen and renewed his call for bachelor's degrees costing as little as $10,000.

Perry offered his latest input on skyrocketing tuition costs in Texas at a Dallas high school Monday.

Perry also proposed tying 10 percent of an institution's state funding to the number of graduates. The governor's office says less than 30 percent of students at four-year schools graduate in four years.

The governor also renewed his call for more transparency so families will know the full cost of a delayed graduation.

Perry's call for a four-year tuition freeze has drawn support from educational leaders, including University of Texas at Austin President Bill Powers.

The governor's office says nine institutions have implemented the $10,000 degree.
