There are various regional and national university accreditation agencies. It is not merely enough to look for an accredited MBA program, you should look at the reputation of the accreditation agency. The top MBA programs have both a regional accreditation and accreditation from the Association to Advance Collegiate Schools of Business accreditation (AACSB). There are six regional accreditation agencies in the United States, which are:
The MSA typically accredits colleges and universities in Delaware, the District of Columbia, Maryland, New Jersey, Pennsylvania, Puerto Rico, and the Virgin Islands.
The NEASC typically accredits colleges and universities in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.
The NCA typically accredits colleges and universities in Arizona, Arkansas, Colorado, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, New Mexico, North Dakota, Ohio, Oklahoma, South Dakota, West Virginia, Wisconsin, and Wyoming.
The NWCCU typically accredits colleges and universities in Alaska, Idaho, Montana, Nevada, Oregon, Utah, and Washington State.
The SACS typically accredits colleges and universities in Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia.
The WASC typically accredits colleges and universities in California, Hawaii, Guam, American Samoa, Federated States of Micronesia, Republic of Palau, Commonwealth of the Northern Marianas Islands, the Pacific Basin, and East Asia.
The AACSB is well respected and has high standards that colleges and universities must adhere to. Most of the top MBA programs have both AACSB accreditation and one of the six regional accreditations.
The DETC only accredits distance learning programs and is thus fairly new and is not as prestigious as the six regional or AACSB accreditations. However, the DETC is growing quickly as more insitutions are developing distance learning programs.
