Marie Skłodowska-Curie Fellowship certificates are now available, upon request, for fellows who have completed a research period within one of the FP7 or H2020 Marie Skłodowska-Curie actions. Marie Skłodowska-Curie Fellowship Certificates can be requested through the project contact person or the legal entity authorised representative (LEAR) or the scientist in charge at the coordinating institution. The Certificate is not compulsory. It is a service offered to fellows requesting proof of their participation in a Marie Curie project.
