The Families Matter series of papers from the Harvard Family Research Project advances the concept of family-centered child care, advocating an approach to early childhood education that addresses the development of the child and family together. Grounded in family support principles, which build on family strengths and work from a community's culture and resources, family-centered child care incorporates positive attitudes about working with parents and practical activities to serve the family. Asserting that a key place to promote widespread use of family support principles and practices is through the child care training system, the papers that make up the series focus on how the child care field trains providers to include family support. This volume in the series examines child care resource and referral agencies (CCR&Rs), private and public agencies that provide support and services to more than 2 million parents and providers. This volume profiles the family-supportive services and training efforts of CCR&Rs, drawing from a national survey and in-depth agency interviews. Innovative delivery of training and strategies for linking this delivery with family-centered training content also are discussed. The report suggests that through their philosophy and services, CCR&Rs demonstrate many ways of moving families from the margins to the center of child care practice, and through more consistent application of this knowledge to training efforts, providers' practices can be influenced. CCR&R agency profiles are included. Appendices contain survey materials. Contains 37 references. (EV)
