The main aim of this paper is to describe a working protocol which can offer practising educational psychologists a rational framework within which to investigate and understand the complex problems of children and young people in school and to provide appropriate advice to teachers, parents/carers and LEA decision makers on how they can best manage such problems more effectively. In particular, the quality of psychological advice (Appendix D) arising from the statutory action assessment process relating to children and young people with special educational needs will be considered, some improvement suggestions will be highlighted and wider issues surrounding the use of such a protocol will be considered.
