This article discusses the use of assistive technology (AT) in the context of three current international trends in the field of intellectual disability (ID) that are significantly impacting the delivery of services and supports to persons with ID: the provision of systems of supports based on the individual's assessed support needs, the increased use of AT, and the expectation that interventions will be founded on evidence-based practices. These three trends are described in reference to a social-ecological conceptualization of disability and a multidimensional model of human functioning. The article concludes with a list of potential research questions that integrate a framework of human functioning, supports, AT, and evidence-based practices. (Contains 1 table and 1 figure.)
