Hmm. Our school is one where those who start ahead tend to stay ahead. We had a few mother's early on insisting that their children were particularly bright. They needed to be going up a reading level/guided reading group/maths group etc. These were the people having 'conversations' with the teachers right from the start.
Curiously, they were usually listened to and these 'intelligent' children were thus 'made' rather than born IMO.
By Y1 this was yet more prevalent. I didn't do it at all I have to say, even when I thought my son merited going up a level/set etc I trusted the teacher to do what was best.
Last year the Y1 teacher admitted to me that the pressure had been immense to do as the parents requested, those in the top set really needed to buck up etc. These same parents were consolidating the curriculum at home on a daily basis. Their children thus pulled further ahead and ended up receiving different work, work that my son was more than capable of IMO.I wish I had spoken out earlier and been more 'visible' at school.
Our school, in Y1, had general ability sets - not differentiated for english or maths and movements were very rare. So those brilliant sparks in reception were the same ones in the top set at the end of Y1.
By Y2 it's the same old story. Finally my son is almost sitting where his current attainment suggests he should be, but I can honestly say if I hadn't said or done anything this wouldn't be the case at all. He's quiet in a large, noisy class of 30.
Not every school works in this way but given what I know now next time around I plan to be rather more pushy and rather more visible shall we say :).
