Access to college is not a given for everyone. Money and geography can both play a role in locking some people out of the promise of a higher education.

With several presidential campaign candidates pushing the idea of free college, On Campus Radio looks at how this idea is playing out in places where it’s already being offered.

We'll visit Tennessee, a state that allows all new high school graduates to enroll in a post-secondary associate or certificate program without having to pay out of pocket for tuition.

We'll also go to Rhode Island, where the Ocean State is in the middle of a four-year pilot for a similar program.

Then, we'll hear from Matthew Chingos, who directs the Urban Institute's Center on Education Data and Policy, about how free college proposals really work and why it isn't always easy as it sounds.
