Words like “cheap” and “basic” do not belong in the same sentence, when talking about care for disabled children and young people with complex neurodevelopmental problems and challenging behaviour.
Who do you think is going to be willing to work in this respite centre, for children who apparently can’t be in schools, because staff shouldn’t be expected to keep them in their sight and below their level all the time?
People are only going to be prepared to work there, when the children and young people are properly assessed for staffing. The staff want to know someone has their back. If they need 2:1, 3:1 or 4:1 in their waking hours, the last I heard (about 15 years ago) was £250,000 pa for 2:1! It takes 3 full time staff to provide 1:1, so 3:1 is going to be at least £325,000 and 4:1 £400,000 pa. Then, the staff really need back up from clinical psychologists, speech and language therapists, consultant child psychiatrists, etc to tell them how to handle the behaviour - none of which comes cheap!
Challenging behaviour arises from unmet needs per The Challenging Behaviour Foundation.
It is as @flawlessflipper says, cheaper to give them the education, which meets their needs, such as how to communicate to get what they want, social skills, how to self regulate, etc in an environment, where they can cope!
Language is an intrinsic and extrinsic regulator of emotion - and children can sound very articulate (because they can regurgitate what they have heard very well); but it doesn’t mean to say they know what it means; or if you asked them how to play Monopoly, they could put the language together to do so; or they understand empathy? Teaching children with social communication problems to say sorry, can just give them the message, they can do whatever they like and all they have to is say sorry, to make everything alright again!
