This article examines the planning processes involved for students with developmental disabilities (i.e., intellectual disability and autism spectrum disorders) as they transition through different stages of schooling in the United States. In order to obtain an understanding of current practices in this area, 167 teachers from three states (California, Texas and North Carolina) were surveyed about transition practices for students with developmental disabilities. The transitions from primary to middle school, middle to high school, and high school to post-school life, as well as home-school collaboration, were the focus. The teachers responded to demographic and open-ended survey questions. Findings indicated that the lack of active student involvement in transition planning remains a serious concern across all three transitions.
