Show answer and explanation
B the federal states die Bundesländer
Why?
School and education policy is mainly decided by the federal states (Bundesländer), so school types and rules can differ between states. This is part of the states' 'cultural sovereignty' (Kulturhoheit). Teachers and universities do not set school policy, and the federal family ministry is not responsible for schools.
Erklärung auf Deutsch
Die Schulpolitik bestimmen vor allem die Bundesländer. Deshalb gibt es in den Ländern unterschiedliche Schulformen und Regeln. Lehrer, Universitäten und das Familienministerium machen keine Schulpolitik.
Remember: Schools = Länder business.
