My son has just had his first day at secondary. He tells me that that his year has 3 top sets and 3 bottom sets for maths. He is in one of the bottom sets for maths inspite of getting a level 5 in maths. He is very pleased because he is with his friend who wasn't entered for SATS and is working at level 2. I imagine that at least half the children got a level 5 in their maths in their SATs.
I am concerned that the level of differentiation to stretch such a range of ablity will be impossible. I am really surprised that the school has not chosen to have 6 sets for maths or maybe 3 sets. It seems odd to have two levels of maths classes when the school has 180 children in the year.
