No. In this case, you don’t need WRGP. You will already get the resident tuition rate offered by your home state. WRGP can only help students from Western WICHE states who are leaving their home state and enrolling in a participating graduate program located in the WICHE region but not in their home state.
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.
