Planned Government changes to school funding could be “extremely destabilising” for teachers, councils in London have warned. Reforms for a national funding formula will not be flexible enough and poor pupils could be disadvantaged, according to London Councils, which represents the capital’s 33 local authorities. In its response to two Government consultations on school funding, the organisation also argues that academies and free schools should not be funded separately from maintained schools. Steve Reed, executive member for children and young people at London Councils, said: “A national funding formula will never have enough flexibility to respond to the specific needs of each school and the pupils who go there.”
