In Switzerland, the main responsibility for education and culture lies with the cantons. They coordinate their work at the national level. The 26 cantonal ministers of education together form a political body to carry out this work: the Swiss Conference of Cantonal Ministers of Education (EDK). Legally binding, intercantonal agreements (known as concordats) form the foundation for the work of the EDK.
The EDK has a secondary function and fulfills tasks that cannot be performed by the regions or cantons. The EDK programme of activities describes the current projects of the Conference.
