The tasks of determining training capacity and setting admission figures are also subject to supervision by the higher education supervisory authority. Higher education institutions or rather the respective Land ministries issue ordinances or regulations on admission figures for the number of available places in higher education. These require education and training capacity to be used to the full, subject to budgetary constraints and the available premises, and to subject-related factors. The quality of research and teaching, and the proper performance of the functions of the higher education institution, particularly in research, teaching and study, must be guaranteed.
