The former education minister and champion of free schools and academies under the last government regrets that independent schools have not taken up his invitation to get involved with the running of the state run independent schools
This idea was always going to be a non starter as the fee paying parents of pupils to private schools would not want to see their money invested in this way and the personnel of such institutions aren't known for their altruism.
Whether a school which becomes an academy would benefit from the sponsorship of a private school is also debateable. The cynicism in me seems to think it would only get involved if it had a vested interest like creaming off its most able pupils with the enticement of scholarships and bursaries.
In view of the market failure of academies to attract the private school sector, might that be a wider indicator as to why they are a bit of a gimmick to help bridge the divide between state and private sector and should instead continue to be maintained under LEA control?
