I wasn't slating ABA, but the way it is done in this country. Applies to TEACHH too.
What I don't like about TEACHH is that the strategies only reach a point. That point is when the person no longer needs a carer or person to help. It doesn't seem to go beyond that.
Prompts and reinforcers are not faded. They are seen to be doing a job and so they stay.
Also, I don't think being dependent on a set of visuals is independence. It might be as independent as a person can get in their lifetime, but for the many that can move on from them, well there isn't really a strategy to enable that.
Lastly, there is an implication in the UK, that TEACHH enables a child to be independent of a 1:1 or carer, or interventionalist, which is a person. I want my child to be DEPENDENT on people, as a NT child would be, to learn, garner information, seek directions, interact, develop a relationship, - as much as they are able and without ever giving up.
