Over the past decade, public policy has increasingly focused on Home-Based Child Care (HBCC) networks as a promising strategy for supporting regulated family child care (FCC) and legally-exempt family, friend, and neighbor (FFN) caregivers. Stimulated by early research findings of networks’ potential to support quality caregiving for affiliated providers (Bromer et al., 2009), in 2015 the federal Office of Child Care officially endorsed the states’ use of Child Care Development Funding to contract with networks to increase the supply of high-quality HBCC (Office of Child Care, 2015). Newer research and a federally-funded brief pointed to networks’ role in improving HBCC quality, citing evidence of promising service delivery dimensions that could be applied to the implementation of networks (Bromer & Porter, 2017; Porter & Reiman, 2015). In 2019, 18 states reported that they were using CCDF funds to support networks as a strategy for building the supply of child care for infants and toddlers (Office of Child Care, 2016).
