I think people should consider the following when claiming that a Grammar will enable local bright children to access a better standard of education:
You would think that if a Grammar School was set up in an area with crap comps. that local bright kids will benefit, yes?
Actually, what will likely happen is that they may do for a year, perhaps 2 if they are lucky. Then the clued up parents who think it is fine for their DC to do a journey an hour each way to school if it means they can go to a selective school (which gets 2% better GCSE results than their local comp.).
Then there are the parents who think it is OK for their DC to travel 2-3 hours each way to school if it means they can go to a selective school (which gets 2% better GCSE results than their local comp.).
Then there are the parents who know it is fine to rent near the school for a couple of months get their kids into the school and then move back out of the area. As the admissions criteria state that “they may be investigated” if they have a rental agreement for less than 12 months.
Then there are the parents who want to hedge their bets. They get the kids to sit the 11 plus in 2,3,4 or more areas. Which ever school they qualify for, that will do fine. Oh, hold on, how will their kids get to school. Who cares, they got a place didn't they. Oh the joys of hanging on the wait lists for those parents to realise that there is no way their kids can get to the school in less than 3 hours.
Then there are the parents who want to hedge their bets. Yes private is nice, bit expensive though. I know, why not send your DCs to a prep school. They can be taught to the test and have a private tutor or two (will work out cheaper than x number of years in private secondary). If they don't get into the selective state school they can stay on at the prep. and try for private secondary as a fall back.
Then there are the parents who don't believe in academic ability, it is all about hard work. Let them do 2,3,4 or more hours of tutoring each week, on top of their school day and throughout their weekend. Ability has nothing to do with it, just getting them into the school is all that matters.
