In the light of recent guidance published by The National Institute for Health and Clinical Excellence (NICE) on the diagnosis and management of attention deficit disorders in children, young persons and adults, Gill Salmon, a consultant Child and Adolescent Psychiatrist based in Swansea, South Wales, and Amanda Kirby, Professor of Developmental Disorders in Education based at the University of Wales, Newport, give an overview of the rationale for involving teachers in the assessment of children with AD/HD and the development and implementation of subsequent educational interventions. They also review the resulting training implications; explore some of the obstacles to multi-agency, multi-disciplinary working; and examine how current special educational needs policy goes hand-in-hand with the tiered approach to provision of child and adolescent mental health services in offering a graduated response to these children.
