A co-tutelage doctorate enables doctoral students to carry out their doctorates in two countries. They are supervised jointly by a faculty member of the Faculty of Arts and Humanities of the University of Cologne entitled to supervise dissertations and a professor at an international partner university. After the successful completion of a doctoral defence, a doctoral degree recognised by the University of Cologne and the partner university is awarded jointly.

The co-tutelage doctorate includes an obligatory stay of at least one semester at the partner university. This is to improve the doctoral researcher's language skills, support his/her intercultural competence, and help him/her become familiar with the research cultures of other countries. This makes later professional work abroad easier and supports international networking.

The conditions for awarding the degree as well as all other details are laid out in a co-tutelage agreement that is prepared for each doctoral researcher individually and is then signed by the doctoral student, the two supervisors, the two deans, and the two rectors.
