UCM, re your comment "Lots of parents try to label their children as being SN because it takes the parenting issue from them. It's then turned over to the government. Therefore, their children are 'special needs'".
Many parents, myself and close friends included, have children who do have special educational needs.
And these needs are routinely denied and/or ignored by the school and the LEA.
Because they don't have, or won't spend, the money required to provide adequate or appropriate support.
I don't know anyone who has attempted to label their child without that child having genuine difficulties in the school environment.
It really does terrify me that these already vulnerable children will simply be cowed into sitting still and shutting the hell up, for fear of being hit by a member of staff.
It would no doubt work, but it would also give the education system even more leeway to ignore the root problems, and to deny the support they are legally obliged to give.
It's all a bit too Dotheboys Hall for me, I'm afraid.
