I understand your point about out of county children taking up Kent Grammar places which must be frustrating if you are having children from miles away taking up spaces from kids who live on the doorstep. However, there are also a lot of Kent kids who come over the border to Sussex for the good comprehensives which we have here.
As I said earlier the net effect often comes down to local boys who passed the 11 plus being forced into to choosing between being displaced to other schools in places like Sittingbourne, two or three hours travel away, or going to the local non-selective boys' school, Wilderness, which is a challenging learning environment to say the least.
But anyway, if the local comprehensives are so good why don't you send your children to them? The fact that you have good local schools open to everyone undercuts the argument that you need to ship children into another county to secure a 'good' education.
In response to Bexley Mum 2, again I am willing to be corrected, but I think that you'll find that all the Bexley grammars have a sibling/distance factor in the over-subscription criteria. So there may well be children who have a sibling in the school who subsequently moved to Kent and get in on the sibling rule. Or there may well be children who live close to the school but in 'Kent'. Although looking at the map where the Bexley schools are situated that seems pretty unlikely. Judd and Skinners are odd because they apply effectively a first past the post system and will, in theory take you from anywhere in the country.
I have problems with children travelling long distances to school in any event. Attending school is being part of a community and once children get to their teens they want to be out in the evenings or at weekends with their friends.
How can they do that if they live miles and miles away? And what about after school activities? How can they fully participate in the life of the school? I don't think that they can. I think that sending your children to a school a long way away runs the real risk of socially isolating a child - just about the worst thing you can do to a teenager, as far as he/she is concerned anyway.
Finally, once they get to a grammar school they have large amounts of homework. How can they do their homework properly if they are spending hours every day travelling to and from school? Can't see it.
