The federal department of education no longer categorizes accrediting agencies as regional or national.
On November 1, 2019, the Federal Department of Education released final rules and regulations regarding Accrediting Agencies.  As per the Federal Register / Vol. 84, No 212: “In general, these final regulations will simplify the labeling of agencies to better reflect their focus.  Therefore, the Department will no longer categorize agencies as regional or national; we will instead include them under a combined umbrella identified as “institutional” or “nationally recognized.”  The terms “regionally accredited” and “nationally accredited” related to institutional accreditation will no longer be used or recognized.”
