This paper examines the role of augmentative and alternative communication (AAC) in fostering the successful inclusion of students with the most severe disabilities in general education. Best practices in AAC are identified and multiple examples of their implementation are presented. Particular emphasis is placed on the need to integrate AAC into daily school life as a means of fostering all students' access to and participation in the general education curriculum. A primary premise is that inclusion must be more than just a place; it must constitute a context in which meaningful learning occurs. It is demonstrated that when administered appropriately, interventions involving uses of AAC can foster students' access to the general education curriculum and acquisition of skills tailored to their individual and diverse needs.
