FIBAA
The International Business Administration Accreditation (FIBAA) was founded in 1994 and hence became one of the first agencies to be accredited by the German Accreditation Council. Since 2002, it has been entitled to award the Seal of the Accreditation Council for degree programmes in Germany. Internationally FIBAA's certificates are not particularly well known.
