IUCA has been included in the World Higher Education Database (WHED). All academic programs of IUCA and GTC regularly undergo accreditation by the EdNet agency, which is a full member of the Asia-Pacific Quality Network (APQN) as well as the European Association for Quality Assurance in Higher Education (ENQA).

In 2025, the EdNet agency became the first and, so far, the only international member of the Council for Higher Education Accreditation (CHEA, USA), the most influential accreditation organization in the United States. Thus, an IUCA diploma has international status.
