Students often cooperate with companies or organisations when writing major assignments, such as theses and reports – for the sake of simplicity called 'assignments’ in the following. In the Examination Order, it is stipulated, among other things, that it is agreed between the student, the university and the third party to which extent the third party's data may be used. An agreement on confidentiality ensures that the third party’s information about internal business matters will not be disclosed to unauthorised persons. Trade secrets are also protected in accordance with the legislation on trade secrets.
