There is a large population of children with speech, language and communication needs who have additional special educational needs (SEN). Whilst professional collaboration between education and health professionals is recommended to ensure an integrated delivery of statutory services for this population of children, formal frameworks should be developed for the exchange of information during identification and assessment of needs and planning of intervention strategies. In this study an audit was carried out to examine practical and conceptual issues which might arise in a piloted communication system between educational psychologists and speech and language therapists. Whilst it was found that 62.8% of newly referred children with SEN had some history of co-existing communication and education needs, it was shown that duplication of work exists and communication is onerous. It was also shown that schools were not fully informed about children's needs. Joint commissioning of services is required to facilitate individual practitioners in collaborating to serve the needs of these children. (Contains 2 figures and 4 tables.)
