I found this to be a useful book. The approach it recommends is based on well-tired principles of positive behaviour management the author's style and obvious personal experience remind the reader to look beyond the challenging or nuisance element of behaviour to consider what that behaviour is trying to communicate, something that is equally applicable for all children - not just those with autistic spectrum disorders. I found this to be a very practical book and believe it would be a useful resource for anyone working with pupils whose behaviour is challenging, but especially those with autistic spectrum disorders.
