A specialized residential unit was assembled at a state residential facility for mentally retarded residents in order to provide services for individuals who lacked functional speech but who were capable of learning manual signs.Program development focused on four areas. First, a routine was designed to engage residents in functional training activities throughout the day. Second, opportunities to teach signed verbal behavior within all components of the routine were identified. Third, structured training sessions were developed to augment training within normal daily living activities. Fourth, multiple staff training strategies were initiated. Initial outcome data indicate that signing skills of both staff and residents improved.In institutional settings there resides a large population of severely/profoundly retarded children and adults who have few functional verbal skills. Many residents who have been institutionalized for long periods of time have little opportunity to learn language. Often staff anticipate their needs and provide objects or assistance before the residents can indicate that something is desired, thereby preempting language initiations by the residents (Oliver & Halle, 1983).Another problem in both institutional settings and in the community is that the composition of residential units is based on age, sex, vulnerability, scores on standardized tests, or county of service rather than on common training needs of the residents. This can result in a hodge-podge environment that makes training difficult.
