I'm a teacher in a Nurture Group.
I have a DS with autism, I am not sure if that's relevant.
I am very experienced and we have plenty of de-escalation strategies at school. We, meaning myself and 2 teaching assistants have asked for restraint training. Not got it.
To keep the anxious child safe two of us have to remove them from the room. We cannot be alone with a child. That leaves one member of staff with the rest of the group, who are also very challenging. If appropriate we evacuate our classroom leaving the child and 2 staff in there. The other children have to be 'taught' in the corridor.
This is a mainstream school.
I am regularly spat on, slapped and kicked. Me and the other staff care very much for the pupils. They are highly rewarding.
Send them to special schools? Nope. They are poor enough but the special schools are academies now. They don't want ge kids with the behaviour problems. Which leaves us dealing with kids they won't.
I don't know what happened at that school. All I see is staff and the pupils under pressure.
