Today, there is a lack of consensus for the full implementation of common programmes recognizing the “highest” level of higher education in Europe. Even though cotuttelle agreements are widely used for international joint supervision of PhD theses, these are merely bilateral and individual case-based agreements, far away from a real joint degree under a legal framework that establishes the programme. This article aims to describe the experience of the authors in the management and coordination of a joint doctoral programme between 2015 and 2019 and the results obtained from the interrogation of official websites about the reality in Europe concerning such programmes. Our conclusion is that, still in the 21st century, there is a huge gap to be overcome before the existence of Joint International/European Doctorates can be considered an everyday reality. Although various attempts have been made in the last 20 years, there is still a long way to go for Higher Education institutions to integrate all aspects of such programmes, and to make them something more and different than an additional Diploma Supplement. In the authors´ opinion, major efforts must be made by the administrative bodies, although the drive of the academic staff is crucial for success.
