Many students live in "doubled-up" housing, where families sharing housing with other families.

State Rep. Brittany Pettersen, D-Lakewood, wants to make it easier for homeless, unaccompanied and runaway students to pay for college. 

Colorado state law allows students under the age of 22 -- who can provide proof of state residency through their parents or guardians for at least one year -- to pay in-state tuition rates at Colorado colleges. But homeless students are often unable to produce the necessary paperwork, and are forced to pay out-of-state tuition for at least three years. 

Pettersen says the difference in cost -- which can be drastic -- is enough to deter potential students from beginning, or completing, postsecondary education. In the Legislature's next session, she plans to reintroduce a bill that she says will streamline the process for these students to prove they are Colorado residents. It failed last session.

Pettersen spoke to Colorado Matters host Ryan Warner.
