On 25 April 1933, the Nazi government introduced a 1.5 percent quota for new admissions of German Non-Aryans—i.e. essentially of German Jews—as core issue of a law claiming to generally limit the number of (Aryan and non-Aryan) students admitted to high-schools (höhere Schulen) and universities. In addition, high-schools and universities deemed to have more students than required for the professions for which they were training their students were required to reduce their student enrollment; doing so, they had to reach a maximum of 5 per cent of German non-Aryan students. The law was supposedly enacted to avoid overcrowding schools and universities,[4] which referred to German concerns at the time that large numbers of students would decrease the quality of higher education.
