ABSTRACT
The term “early intervention” has been applied to a variety of services and supports offered to young children with disabilities, or those children at-risk for disabilities, and their families (Bailey & Wolery, 1992). Children from birth to 8 years of age might be considered appropriate for early intervention based on the rapidity and types of human development occurring in these years. In this paper, we include descriptions of early intervention (El) principles and practices and a review of the status of OBM in early intervention. Related literature is reviewed for implications affecting the adoption of OBM practices in El. We devote final sections to descriptions of opportunities for research and challenges to applying OBM practices in early intervention services.
