Let me get this straight, Trump “university” is not event accredited by BBB, but the Con Man goes around touting the supposedly “A” rating.
The rating and accreditation are NOT connected to each other. Accreditation comes from becoming a “member” of the BBB by donating.
The rating is based on complaints received.
As far as I know, being accredited does not affect the rating at all, although some potential investors/buyers will look for BBB accreditation as a sign of an upstanding business.
