Are there any legal documents that assure selective status of grammar schools that converted to academies?
From this website:
The academy scheme has been controversial, not least because there is concern that creaming off the funds used for central educational services to academies would deprive other, more needy schools of resources.
There were also initial suspicions that grammar schools might lose the statutory protection of requiring a parental ballot before they are turned into comprehensive schools. These fears were denied by the government, which claimed that there would be no change to the selection arrangements for grammar schools that chose to convert. These fears seem to have abated, although some grammar schools may have stepped back from the brink while they wait for more clarification.http://www.elevenplusexams.co.uk/schools/grammar-to-academy-status
What if in 2015 a new goverment decides to require that grammars stop being selective or cuts the funding?
Even if that is not very likely, is it still a remote possibility? I imagine it could only affect those applying from at least 2016.
