Education Bill

My Lords, the question of evidence is close to my heart, having chaired the Science and Technology Select Committee. I absolutely agree that we should achieve an evidence-based policy. Seldom do we do so, but we ought to. My question is simply this. If there is no evidence that this is needed, is there evidence that training is needed, in the many other provisions of the Bill? We are all very strong on the importance of training. I am just concerned about having blanket legislation that could rule out the unforeseeable—and I think we have accepted that just occasionally some teachers have experienced that.
