Most programs extend the WRGP rate to a student for the duration of their graduate studies, or a reasonable time to complete them. Most institutions don’t make you reapply each year, but some do; check directly with your enrolling institution to find out what the rules are. In all cases though, WRGP students must maintain good academic standing to keep their discounted tuition rate.
Colorado is one of the most educated states in the nation, ranking high in the percentage of adults who attended college and hold bachelor's degrees. But state funding for higher education isn't what it used to be -- according to the American Council on Education, state support shrank nearly 70 percent between 1980 and 2011. The same study says funding could dry up completely by 2019; so perhaps it's no coincidence that the revenue public colleges and universities here get from tuition has increased every year since 2007.
