Emily Bouck, policy and advocacy director at Higher Learning Advocates and previously served as deputy legislative director to U.S. Senator Marco Rubio (R-Fla.), writes:  While it may not receive the same splashy headlines as student debt, our accreditation system holds the key to ensuring the quality of America’s colleges and universities and strong stewardship of taxpayer dollars.  America’s approach to higher education quality is the result of decades of gradual policy change and arrangements between government and academe convenient at the time, but no longer adequate for community and workforce needs. Accreditation began as a regional process of voluntary peer review in the 19th century, but has turned into something very different.
