We are a way off this but I was browsing the entrance requirements of our nearest Trafford grammar - which told me that 50% of children come from Manchester LEA, as places are given on a combination of score and distance (we are on the border). But when I look at the Manchester secondary school nearest to us you have to be in a feeder primary school to get a place. So, it looks to me like Manchester children can attend Trafford schools (the selective ones, at any rate) but Trafford children can't attend Manchester schools. Is that right?
