The focus of current research for children with autism spectrum disorder transitioning to adulthood addresses the negative outcomes in employment, postsecondary education, socialization, community integration, and financial effects from the parent perspective. Currently there is little known about the parent experiences of transitioning their child to adulthood from a qualitative perspective. The purpose of this qualitative phenomenological study is to explore ASD adults transitioning from the parent lived experience. This study is grounded in symbolic interactionism which includes tenets of how interactions with others provide a catalyst for meaning development and subsequent human action. A phenomenological design is used with a purposeful sample of 8-12 parents of children with ASD transitioning to adulthood. Interviews will be conducted with a Zoom platform or phone calls to explore participant perspectives transitioning their child with ASD to adulthood. Interviews with parents provides access to in-depth, rich information to answer the research question. Thematic analysis will be applied to the data by coding, categorizing, and building themes from the parent information.
