I got back my book that I was going to steal the info on copying from. I had forgotten how very good it is and I really think you should get a copy. Its a little dated and is US-orientated but has good stuff on What to Teach, How to Teach and a chapter on School Inclusion that I think you would find interesting (ignore US stuff). I'm sure I mentioned it to you before, so sorry to be an ABA bore!! The info is:
Behavioural Intervention for Young Children with Autism by Catherine Maurice and Gina Green, Stephen Luce ISBN # 0-89079-683-1, Available in the UK from Taskmaster Ltd, Morris Road, Leicester, LE2 6BR, Tel: 0116 2704286 www.taskmasteronline.co.uk (their website is crap).
Not sure of cost, would say £20-£25.
