ABSTRACT
High-technology, aided Aided augmentative and alternative communication (AAC) systems include electronic or powered components. These devices include speech output, speech-generating, and the ability to store and retrieve messages. Thus, assessment focused on identifying an appropriate display is essential in the communicative competence of students with AAC needs. While various research supports the use of an array of displays, the goal is to select a display that encourages efficient symbol use while considering student preference. High-technology AAC systems are comprised almost exclusively of symbols to facilitate the student's communication. The messages section is primarily focused on evaluating how symbols are used to create messages and how they are emitted to the communication partner. There are two types of selection techniques, direct and indirect. Fortunately, some manufacturers will loan a device so the AAC team can conduct an assessment and to give the student a brief period to try out the device prior to making a purchase.
