The Department for Education is carrying out a consultation on setting up a compulsory registration and monitoring scheme of children who are educated at home or not in mainstream schools. It ends on 24th June 2019. If you home educate your children this could result in a significant change as proposals include making a school attendance order for children whose parents fail to register them or whose education is deemed to be unsatisfactory.
