What was the first charter school?
Charter school
Due to Art. 7 of the Grundgesetz (German constitution), private schools may only be set up if they do not increase the segregation of pupils by their parents' income class.[24] In return, all private schools are supported financially by government bodies, comparable to charter schools. The amount of control over school organization, curriculum etc. taken over by the state differs from state to state and from school to school. Average financial support given by government bodies was 85% of total costs in 2009.[25] Academically, all private schools must lead their students to the ability to attain standardized, government-provided external tests such as the Abitur.[26]
