The Ministry grants licences for schools to operate, develops policies to guarantee the right to education and freedom of education, proposes changes to the legal framework governing education, develops compulsory components of the curriculum, monitors school and student performance, and assigns and distributes school subsidies. There is a difference in the degree of autonomy between municipal and privately managed subsidised schools (in which more than 50% of students are enrolled), including administrative, financial and work restrictions. Privately managed schools have full autonomy. Municipal schools also have high levels of autonomy: about half of the decisions that affect educational practice take place at the school level with the remaining half at the municipal level.
