Antisemitic legislation passed in 1933 led to the removal of all Jewish teachers, professors, and officials from the education system. Most teachers were required to belong to the Nationalsozialistischer Lehrerbund (NSLB; National Socialist Teachers League) and university professors were required to join the National Socialist German Lecturers.[344][345] Teachers had to take an oath of loyalty and obedience to Hitler, and those who failed to show sufficient conformity to party ideals were often reported by students or fellow teachers and dismissed.[346][347] Lack of funding for salaries led to many teachers leaving the profession.
