This paper reports findings from an evaluation study of the Communication Aids Project (CAP), focussing on the perspective of children at points of educational transition and the parents, education staff and Speech and Language Therapists who support them. All participants took part in structured interviews, the individual children face-to-face on a one-to-one basis and the adults over the telephone. Those involved with the study reported positive effects of the communication aid, including in speech and communication activities relevant at transition. They also raised three main concerns regarding the use of the aids during and after transition, namely the portability and security of aids in the new setting; managing the flow of information between schools and in particular the availability of continued training in the support and use of communication aids.
