'Free schools' are a recent introduction by the coalition government which basically allows anyone to set up a school in response to need. See definition:
"Free Schools are non-profit making, independent, state-funded schools. There is not a ’one-size-fits-all’ approach. They are not defined by size or location: there is not a single type of Free School or a single reason for setting them up. Free Schools could be primary or secondary schools. They could be located in traditional school buildings or appropriate community spaces such as office buildings or church halls. They could be set up by a wide range of proposers – including charities, universities, businesses, educational groups, visionary teachers or committed parents – who want to make a difference to the educational landscape. They might be needed because there simply are not enough school places in a local area and children have to travel too far to the nearest school.The thing which unites all Free Schools is that they are being set up in response to real demand within a local area for a greater variety of schools, they meet rigorous standards and they are all absolutely committed to providing young people with the best possible chance to succeed."
You can set up schools on the basis of gender and religion, but not race. I think the idea of one for boys which offers dance is a great idea. I think I also read about one that is going to set up on the basis of military discipline for parents who think that current state schools offer little in this area. Free schools are about responding to requirements of parents and children and increasing choice, moving away from the 'one size fits all' comprehensive state education, controlled by local authorities.
