An ABA Primer (with application to teaching children with autism) can be of immense help to the parents and instructors of children with autism since (1) it is inexpensive, particularly as an e-book, (2) it provides a very good introduction to teaching in general and teaching children with autism in particular, (3) it can guide parents through the entire process of getting their children to be able to fit in educationally and socially, (4) it tells you the skills to look for in supervisory staff, and (5) it provides a list of almost thirty common ABA errors which you and any staff you hire might want to avoid.
