This project was undertaken to collect information on the services offered to people with learning difficulties in seven diverse local authorities of the country and to involve providers of service in a systematic examination of it. A random sample of those people with learning difficulties in the community and under the age of 30 was drawn from the seven areas. Questionnaires were administered to parents, general practitioners, mental welfare officers, health visitors and school teachers. This volume comprises the findings from the records kept on the cases in the sample at the mental health departments.
