Robert Kelchen and Luke J. Stedrak:

States have traditionally provided funding for public colleges and universities based on a combination of the number of students enrolled and how much money they were allocated previously.

But, in the face of increasingly tight budgets and pressures to demonstrate their effectiveness to legislators, more and more states are tying at least some higher education funding to student outcomes.

As of 2015, 32 states have implemented a funding system that is based in part on students’ performance in at least some of their colleges. In such states, a portion of state funding is based on metrics such as the number of completed courses or the number of graduates.
