Since 2006/07 the Universities of Trento, Regensburg and Budapest issue a Joint Diploma and a Joint Diploma Supplement to students who successfully complete the programme. The University of Ljubljana joined in 2010.
Master CoDe was part of a pilot EU project aiming at a joint accreditation process at the European level. The project implementer was the Dutch Accreditation Agency, while Master CoDe accreditation was coordinated by the Hungarian Accreditation Committee in cooperation with the German Accreditation Council and the Slovenian Council for Higher Education.
The project started in June 2009 and was successfully concluded in June 2010 with Master CoDe accreditation by the European Consortium for Accreditation.
