Children with disabilities, and those with physical and intellectual disabilities in particular, need co-ordinated multidisciplinary approach as no single profession can hope to achieve very much single-handed. In order to provide appropriate services we should work with and through others who interact with these children. While one of the hallmarks of the good professional is collaboration, collaborative practices are all too infrequent. Some related problems currently affecting the development of services for children with special needs in the U.K. are outlined. Examples of actual and possible productive practice between and among teachers and other professionals are provided, with the desirability of active and systematic joint planning and problem solving, emanating from a base of shared training, stressed.
