Henning Graner co-founded one of the first Democratic Schools in Germany in 2008 and has been working there ever since as a staff member. In 2010 and 2013, he and other activists launched a popular initiative to change the Berlin school system: Schools should be able to shape the content and quality standards of their work autonomously and all schools should be funded equally. In 2023, Henning was one of the initiators of a resolution adopted at the International Democratic Education Conference in Nepal. The resolution clarified that the wording “compulsory education” in the Convention on the Rights of the Child is only meant as a guarantee of access to education, not as forcing the child to attend a school in violation of the best interest of the child.
