The study of transition process for young children with disabilities and their families is complex. This complexity is reflected in efforts by researchers and policy makers to understand the phenomenon and determine ways to improve the transition experiences and outcomes of young children with disabilities and their families. This article synthesizes the literature from early childhood special education as well as general early childhood in an effort to exemplify the current understanding of transition processes and practices. Future directions for more integrated approaches to transition research, policy, and practice are presented. (Contains 1 figure.)
