The successful implementation of an augmentative and alternative communication (AAC) system often depends on the quality of the training of the communication partners. This single-subject, multiple-probe investigation was designed to determine whether using specific teaching strategies with the communication partners of adults with complex communication needs (CCN) in Guatemala would improve the quality of communicative interactions through the increased use of open-ended questions, expectant delay, and aided AAC modeling using a static visual screen display (VSD).
