It is right that schools set their behaviour policies, but of course those have to be reasonable, and that is what we expect throughout the system. We have guidance on these things, and as part of the response to this report, I have committed to update the guidance on a range of matters relating to exclusions and behaviour, including that one. That is not to say that the use of isolation as a punishment and a deterrent is wrong in all cases. When people use that term, it does not mean the same thing in all schools, and what the hon. Gentleman describes is not necessarily what we find in other places.
