PhD students perform training/research periods (each of at least six months) in two or more European Consortium partners.
Home institutionThe full partner institution that draws up the employment contract with the student, is called the 'home institution'.
Host institutionAny other institution where the student spends training/research periods is called a 'host institution'.
One or more of the institutions (including the home institution) where the student performs training/research may be a non-degree awarding research institute (NDRI). There, the student is guided by one or more mentors. An NDRI may appoint a (co-)promoter in a Higher Education Institute (HEI), which is a Consortium partner. This HEI needs to have a strong affinity with the NDRI (e.g. when the director of the NDRI or a mentor at the NDRI is also a professor at the HEI). This HEI then officially takes part in awarding the degree (this is already common practice in fusion research in Europe).
The thesis proposal should be submitted by at least two degree-awarding HEIs. One of the HEIs is, or has been appointed by, the home institution. The professors in these HEIs are the promoters of the PhD.
On successful defence of the PhD thesis, these HEIs award the double/multiple or, preferably, joint PhD degree. It may happen that, although the NDRI where the training/research was performed is a full partner, the linked HEI that is appointed to jointly award the degree is an associate partner. In this case the associate HEI is required to agree before the submission of the thesis proposal that it will provide a double or joint degree. This will be an incentive to move even more universities toward co-tutelle.
