I wonder which schools have already posted their applications in the post box!
It is going to be fascinating who is going to be the first to declare their intention to become a grammar. I personally think the first out of the box if you like will be Dame Alice Owen's , the two Watford ' Grammars' and other 'Comps' of similar ilk!
However, the proposals stating that any school can become selective, could lead to some interesting other potential ideas ! A 'bizzare' but feasible is the possibility that a high performing Modern school (such as Wellington/Waddesdon ) could set an exam . The exam might be set at a level that 80 % of the current cohort would pass, however meaning the few low ability pupils would not pass.
This means you would have the 'strange' situation of 'Grammar' being created (albeit a low admittance one).
