IF: Is it allowed for the MSCA IF researcher during the research project running time to be part-time involved in the teaching course at the hosting University?

Teaching can be considered as a complementary research competence within the Marie Sklodowska Curie Actions although this activity must not jeopardize the execution of the research projects as set out in the Grant Agreement. Any teaching activity shall not be substantially relevant in terms of time devoted to it, and should be preferably mentioned in the proposal.
Nevertheless, specific requests received during the project implementation will be examined on an individual basis, taking into account the career development of the fellow. Such requests would then be approved by the Project Officer on a case by case's basis.
