She said in a press statement that,"Our forty five years' of experience have shown that our most able children work best when they are being stretched and challenged with like-minded peers or in classes where activities are well-differentiated. Teaching to the average drags everyone down but having low expectations for those with high potential can be particularly damaging on the learning of the child and their social and emotional development. This is not good for either the child or our position in the education league tables. At NAGC, we have seen too many able children coast, underachieve or even drop out of education altogether where, with the right support, they can maximise their potential.

"There are some excellent schools out there that are working hard to support their most able pupils. Let's learn from them and raise our performance in every school in the country."
