Why does the state control the education system in Germany?

1. because there are only state schools in Germany
2. because all students must obtain a school-leaving certificate
3. because there are various types of schools in the federal states
4. because it is its duty according to the Basic Law ✓

Article 7 of the Basic Law places the entire school system under state supervision, so overseeing schools is a constitutional duty. Within that framework each of the 16 federal states runs its own school system, which is why school types and holidays differ from state to state.
