The Masters in Psychology and Counseling Accreditation Council (MPCAC) is an alternative to CACREP, at this time primarily being utilized by counseling psychology graduate programs (which are largely shut out of CACREP because of having psychologists on their core facilities). MPCAC is in the process of obtaining recognition by the Council for Higher Education Accreditation (CHEA).
Some of the primary differences between the two involve MPCAC allowing other professions to serve as facility for greater diversity of training, and requiring course work in social justice. An older analysis of the two sets of requirements is available here.
At this time there are six programs that are MPCAC accredited with several more in process. These include programs at University of Massachusetts, University of Wisconsin, University of Missouri-Kansas City, University at Albany, and Felican College.
