There is also a "national" accrediting agency called DETC, however, its accreditation though recognized by the government http://www.ed.gov/admins/finaid/accred/accreditation_pg8.html#det is not considered nearly as valuable by most employers and universities as regional accreditation, so this accreditation should not be considered adequate when selecting the best online degree programs.
