The AAC/AT Interdisciplinary Assessment Team Initiative is a collaborative effort between the Exceptional Children Division of the NC Department of Public Instruction and the Carolina Institute for Developmental Disabilities (formerly the Center for Development and Learning) at the University of North Carolina at Chapel Hill. The goal of this ongoing project is to establish a network of school-based teams that have the capacity and capabilities to effectively assess children with significant communication difficulties and to determine their need for alternative or augmentative communication systems or devices.
