In 2014 the German Academic Exchange Service (DAAD) initiated the programme "Postdoctoral Researchers International Mobility Experience" (PRIME) to support the international mobility of postdoctoral researchers by temporary positions at German universities in place of conventional scholarships. The programme has been funded by the German Federal Ministry of Education and Research (BMBF) and the European Union (EU/FP7/Marie Curie Actions/COFUND). Funding is provided for 18 months, in which 12 months have to be spent abroad and 6 months (re-integration phase) at a German university. The re-integration phase is mandatory. The German university administrates the salary during the whole funding period.
