Georgia's public colleges and universities will have to earn the money they get from taxpayers by helping more students get a degree.

The change is part of a new funding formula approved Wednesday by a commission appointed by Gov. Nathan Deal.

The new formula links the state funding colleges receive to their improving student success and the number of degrees or certificates awarded.

The plan won't go into effect for a couple of years, but it represents a drastic shift from the current system that focuses on enrollment and how many credits students take, with little attention paid to whether they ever graduate.
