International activities in both research and teaching are central to the Department of Cultural Policy. The UNESCO Chair "Cultural Policy for the Arts in Development", which is hosted by the Department since 2012, is key to its internationalisation strategy. Moreover, strong ties and a long history of cooperation and shared projects links the Department to the Aix-Marseille Université in France. Core projects include the two-year double degree programme Kulturvermittlung/Médiation culturelle de l'Art (M.A.) and a Franco-German PhD-Track, both supported by the Franco-German University.

For B.A. students, the Department - together with the faculty - developed a four-year programme called Bachelor Plus "Cultural Policy in International Contexts". Selected students spend a year abroad - mixing studies and training - in either France, Turkey, Lithuania, Morocco or South Africa. The programme includes a phase of intensive preparation in intercultural matters and international cultural policy questions before going abroad, as well as a follow-up upon returning to Hildesheim. Erasmus Agreements with numerous higher education institutions across Europe offer further study abroad opportunities.

In West-Africa, the UNESCO Chair, together with the Center for World Music, is active in the project SDG Graduate School "Performing Sustainability. Cultures and Development in West-Africa" which receives funding from the DAAD and explores the role of the arts in situations of conflict and processes of social transformation.
