The Erasmus program is the largest mobility program at TU Dortmund University. The exchange of students is based on Erasmus+ contracts, which the respective faculty has concluded with partners at foreign universities. The Faculty of Social Sciences currently has contracts with about 10 universities in Europe. On average, 2-3 places are available per university.

As part of an Erasmus stay, students can study abroad for one or two semesters. Thereby, any tuition fees are waived, and the academic achievement done abroad can be recognized at the home university. In addition, there is a mobility grant, which depends on the destination country. Scholarships or grants can usually continue to be obtained in parallel.
