Without going into the actually history of the two accrediting agencies, there are a few issues that should concern individuals when choosing between regionally and nationally accredited colleges and universities.
For one, the regional accreditation standards are higher than that of the national accreditation agency. Thus, the regional accreditation is preferred by colleges and universities who wish to be recognized as institutions that possess excellence within higher education.
Second is the issue of transferability of credits. Nationally accredited institutions typically accept credits from regionally accredited colleges and universities, where regionally accredited colleges and universities will not accept credits from nationally accredited institution. This means if you have a coursework and/or a degree from a nationally accredited institution, it would be like starting all over again should you decide to transfer to a regionally accredited school (which most all recognized colleges and universities are). This should also be a great concern should you plan on pursuing advance degrees (master’s, doctorate) at a later date. The degree from a nationally accredited school would not be recognized.
Third, employers who are aware of the difference in regional and national accreditations may not recognize your education that was completed at a nationally accredited institution
