Abstract
The current status of preventive intervention programs for young children at environmental risk designed to reduce the school readiness gap is examined in the context of developmental science. A review of program effectiveness suggests that future progress may depend upon committing to a specific developmental approach consistent with the knowledge base of developmental science and establishing a generally agreed upon and unambiguous framework, set of goals, and associated mechanisms. The Developmental Systems Approach is suggested as one model that is consistent with developmental and existing intervention science, supporting an emphasis on program continuity, relationships, and comprehensiveness. A long-term plan for community-based systems development is presented.
