Tool for families, educators, teachers: what have I read this earlier! The book is not too technical, rather accessible. Objective enough (ie neither too pessimistic nor too optimistic). Lets take a step back in many situations, to enlighten behaviors or thoughts turnings ... The title "Understanding" is really well chosen. Special message to teachers: let alone "diagnostic", openness to other types of behavior and other ways of thinking - not quite in the standard, nor quite extraordinary - is present in this book.
