Oh wow, this post is something else!
The outcomes for children in care, or previously in care are generally pretty poor.
My two children were taken into care at the age of 14 months and just over 2 years old.
By the age of 2 and a half and three and a half, they had a brand new mum and dad and a boat load of trauma to deal with. I'm surprised they are still standing quite frankly.
But they are, and they are meeting expectations. They bloody amaze me..every day.
I wouldn't put them through the 11+, because I would feel it would be just too much for them. They are still standing and doing ok - that's quite a feat after what they have been through.
Children who are in care or who were previously in care, do get first priority on school selection. It is literally one of the very few benefits they get.
Imagine getting a brand new mum and dad at that age (and not all of them even get that), having to deal with all the shit that life's already piled on you, and then someone else getting pissy because, for once, you were allowed at the front of the queue.
BTW - they only get to the front of the queue, not because everyone cares so much, but because they get extra funding for the school - for the school, not for them personally.
