The design and implementation of early childhood intervention programs: informing efforts to address risk and promote resilience.

With the goal of narrowing disparities in children's school success, a growing number of innovative early childhood interventions have been launched. As these interventions begin to show evidence of enhancing children's development, it is important that we understand the design of these interventions and their implementation. This themed issue of the Journal of Prevention and Intervention in the Community includes four articles that each highlight a different early childhood intervention program, and a fifth article that provides a commentary on the main set of articles, from a community perspective. The first article focuses on children with autism spectrum disorders (ASD) and a program that sought to integrate children with ASD into public schools. The next two articles center on children from low-income families, with a focus on preschool classrooms. The last article discusses a program that aimed to foster young children's school readiness as well as families' readiness for children's transition to school.
