My ds(9) is just finishing Y.4, and for the last 2 years he's been in a mixed-age class with older children. He's bright, although he doesn't always apply himself, and this arrangement seems to have worked well as he naturally gravitates towards older children. However, for next year the school has divided the new Y.6's into two equal groups and added the brightest Y.5's - except that he's been separated from that group and put with the remaining Y.5's and a few bright Y.4's. I went in to question it as I was concerned that he would either be naughty because he was bored (as happened in Y.2 when he was in a mixed Y1/2 class) and/or stop making progress and adapt to the generally lower standards of the others.
I was told that they felt he thrived on responsibility and so would benefit from being one of the older ones. They denied classes had been divided by ability (which they obviously have if you know the children) and feel confident that he will be stimulated enough. I agree that he does respond well to being assigned responsibility, but I don't consider that to be particularly relevant within the classroom as he's there to learn and not just to help others. The teachers (a job share) are good, but I just worry that he won't be stimulated enough by the other kids to learn, and he said when they had a trial in the class the other day that he was the only one who knew what 'distinguishing' meant(!)
The question is: should we give up trying to change the school's mind (which I don't think will be changed), should we talk to the new teachers, should we just hope for the best - or am I just being precious?
