Even in the digital era, the regulation of educational institutions is left to each state. The resulting array of requirements confuses both students and institutional faculty and staff. The State Authorization Reciprocity Agreement (SARA) was created to apply consistent review standards across the states.
An institution approved in its home state is eligible to enroll students (within limits) in any other SARA member state. As of this writing, 36 states have joined in a little over two years. That number may approach 45 by the end of 2016.
