People who cannot communicate through spoken language need support in communication and the development of their communicative skills. The book demonstrates how to establish access to individuals with communication impairments or autism spectrum disorders using the communication concepts PECS and TEACCH, both of which utilize visual signs, without the need for elaborate or expensive materials. This enables these individuals to express themselves, understand others, and build social relationships. The authors have been working with these two communication systems for years and share their personal experiences in implementing the concepts through case studies drawn from their extensive practical experience. The CD includes working templates such as questionnaires on the status of communication ability, PECS checklists, documentation of the PECS phases, and more.
