Query: A good overview of ABA therapy

A very well written book which is easy to read and is good value. I would recommend it be used in conjunction with " A Work in Progress" by Leaf and McEachlin to understand ABA therapy for Autism. "The ABA Program Companion" book gives an overview of what ABA is, rather than a specific program. A "Work in Progress" gives a specific comprehensive program especially suited for a younger child.As a parent (and qualified school teacher), I have used the book to give my son therapy whilst waiting for Professional Services to become available and found it most useful.You may want to borrow a copy instead of buying it, if you are a parent as it mainly provides background information.
