Since the 1988 Education Reform Act, parents have a right to choose which school their child should go to or whether to not send them to school at all and to home educate them instead. The concept of "school choice" introduces the idea of competition between state schools, a fundamental change to the original "neighbourhood comprehensive" model, and is partly intended as a means by which schools that are perceived to be inferior are forced either to improve or, if hardly anyone wants to go there, to close down. Government policy is currently promoting 'specialisation' whereby parents choose a secondary school appropriate for their child's interests and skills. Most initiatives focus on parental choice and information, implementing a pseudo-market incentive to encourage better schools. This logic has underpinned the controversial league tables of school performance.
