The Communicative Development of Toddlers with Cerebral Palsy (COCP) project developed an assessment-intervention program for non-speaking children with cerebral palsy. The goals of the project's Assessment-Intervention protocol are to teach the child to communicate in an appropriate, effective, and efficient way in different situations and with different communication partners, and to teach communication partners to stimulate the communicative behavior of the child, in particular by adapting their own behavior to the communicative needs of the child and by modeling the use of communication aids. The program is aimed at different communication partners, including parents, other important adults in the home environment, those responsible for the child's transport, teachers and teachers' assistants, and therapists. Use of the protocol involves gathering background information, conducting a formal assessment, describing communicative behaviors of both adult and child, setting goals, developing an intervention plan, implementing the intervention, and conducting an evaluation. A case study illustrates use of the protocol. Three figures are included. An appendix lists 10 strategies to facilitate communicative interaction. (JDD)
