The Higher Education Law distinguishes between two categories of academic staff in higher education. These are professors and other staff (among others assistants, academic associates, lecturers, guest lecturers). Professors are holders of the relevant teaching qualifications or of other expert know-how and pedagogic eligibility; they are appointed in an appointment procedure determined by the higher education institutions. The title of a professor is bound to the activities at the higher education institution. Further academic staff includes persons with the relevant expert know-how and pedagogic eligibility. Their appointment is not determined by an appointment procedure. The structure of the academic staff together with other regulations on higher education staff are determined in the organisation guidelines as well as in the service and salary regulations by the supreme management body of the higher education institution; the same applies to the relevant pay table and fee regulations.The labour law and service law relevant to the academic staff are determined by the higher education institution within the framework of superior legislation (cf. Art. 33).
