The chapters which constitute this book are based on papers delivered at the International Special Education Congress held in Cardiff in the summer of 1990. At this conference staff training was one of the central themes on which the call for papers was based. The decision to make staff training a major focus of the congress was a bold move on the part of the organisers, for while many appear to recognise the importance of specialised staff training in relation to special educational needs, few have written about it or spoken about it at national and international conferences.
