We estimate that 38 per cent. of current head teachers will have retired by 2015. Dealing with the loss of their skills and experience will be a challenge and an opportunity. We have invested £30 million through the National College for Leadership of Schools and Children's Services succession planning strategy to ensure that this demographic challenge is managed effectively. The national college continues to work closely with schools, local authorities and faith bodies around the country to find, develop and keep excellent head teachers.
