In the case of an individual doctorate, a doctoral candidate is supervised by a supervisor through talks on the work on the dissertation (at least twice per semester) and possibly by private supervisors / colloquia held by the supervisor.
As a rule, the doctoral candidate is not involved in any superordinate structures and is therefore relatively independent. At the beginning, he / she chooses a supervisor with whom the dissertation topic is determined. Ideally, an application for admission to the doctoral program will then only be submitted to the study and examination department.
Many individual doctorates do not come within the scope of employment relationships or with the support of scholarships; the duration therefore always depends on other professional activities that are undertaken to finance the doctoral program.
A decisive advantage of this type of doctorate is the possibility of free time allocation, however, due to the lack of involvement in a group of researchers (supervisors as well as doctoral students), a high degree of independence and self-motivation for a successful and timely (three to five years) permanent doctoral degree necessary.
