This paper presents a summary of best practices for communication assessment and intervention with individuals who are deaf/blind and have a severe intellectual impairment. Focus is on individuals who have difficulty both receiving and understanding auditory, visual, and tactual information. The impact of sensory losses on communicative development is considered, followed by a discussion of general practices for communication intervention which stress a functional approach linking assessment and intervention and a multimodal delivery form. Means of facilitating communicative development include creating an optimal communication environment, using the team approach effectively, developing augmentative communication modes, and using compensatory teaching approaches and prompting techniques that bypass the sensory impairment. Recommendations address collaboration between organizations, increasing the number of potential communicative partners, early intervention, utilization of technological advances, and personnel preparation and inservice training. The paper concludes with a list of 52 references and related resources including 20 related articles, 5 assessment tools, 15 monographs and books, 9 video training tapes, 6 organizations, and 8 technological aids.
