The authors describe the research and evaluation activities connected to the new Maternal, Infant and Early Childhood Home Visiting program. The goal of these activities is to provide information on federal, state, and local efforts to strengthen programs by providing much needed knowledge on the best ways to support the implementation of home visiting programs at multiple levels--with families, home visitors, supervisors, organizations, and others. The collection of research and evaluation activities has a strong emphasis on capacity building, both for grantees and for the research community as a whole. This article aims to support the dissemination of research to the practice community by highlighting the resources currently available and to come.
