Family child care (FCC) providers often experience isolation from other early childhood and child care professionals. Yet, research suggests that providers who network with other providers, engage with community resources, and belong to support groups tend to offer higher quality child care. For example, the Family Child Care Network Impact Study found that relationship-based network supports delivered by a specially trained staff person were associated with higher quality caregiving among network-affiliated family child care providers. The authors present the study and describe the dimensions and components of a relationship-based training program, developed on the basis of the research findings, for support staff members who work with FCC providers.
