This research brief presents findings from a targeted literature review on home-based child care (HBCC) networks that support HBCC providers, including regulated family child care (FCC) providers, and/or family, friend, and neighbor (FFN) providers who are legally-exempt from regulation. The review was conducted by the Erikson Institute to inform the development of the benchmarks and indicators for HBCC networks that are described in the companion brief, Strengthening HBCC Networks: An Evidence-Based Framework for High Quality.
