The National Institute of Child Health and Human Development (NICHD) and the National Council for Accreditation of Teacher Education (NCATE) collaborated on a child and adolescent development project involving roundtables of knowledgeable researchers and teacher educators. This summary report discusses major issues faced by teachers and schools, and the resources needed to address them---such as translating child and adolescent development literature into a user-friendly format for delivery in courses and links to the accreditation process. The underlying premise guiding the roundtable discussions: If educators are to empower all individuals to learn, they must know and be able to apply information from human development and cognitive science within their own professional practice. The following issues were discussed: (1) the state of practice in teacher education highlighting the ways in which child and adolescent development research is currently integrated into teacher preparation curricula; (2) ongoing investigations of child and adolescent development from selected research studies, and how aspects of these studies may be applicable to teacher preparation; (3) issues and challenges in translating research to practice; and (4) applications and action steps for linking child development research with teacher preparation practices. This report highlights principles and theories derived from ongoing research studies and investigations presented at the roundtable meetings. The focus of the discussions centered largely on the social and emotional domains of development, with the expectation that other domains will be explored at future meetings. Specific policy recommendations based on the ideas presented in this report are beyond the scope of this collaboration. The summaries of research and the corresponding questions raised in this report may help NCATE frame their standards and set their agenda for improving practice at all levels of the education system. The following are appended: (1) The Integration of Child/Adolescent Development in Teacher Preparation Programs at NCATE-Accredited Institutions: Survey Results; and (2) Child and Adolescent Development Research and Teacher Education: Evidence-Based Pedagogy, Policy, and Practice--Research Questionnaire.
