A single-subject, alternating-treatments with no baseline design was used to study the effectiveness of work systems in three children with autism. Work systems build on the strengths of children with autism, taking advantage of their visuo-spatial strengths by building on the principles of visual cueing and organization. Individual work systems were developed for each child, and the effects of these systems on on-task behavior, dependence, productivity and organization were studied. Results indicate moderate significance for the effectiveness of work systems in increasing on-task behavior and decreasing dependence in children with autism. Results also revealed substantial evidence for the effectiveness of work systems in increasing organization in these children. Most important, this study illustrates that successful empirical research can be conducted on work systems and their effects on children with autism.
