This brief defines peer support and describes how peer-to-peer sharing can enhance the effectiveness of family child care support initiatives. Peer support strategies may enhance provider well-being and sustainability, increase provider engagement in publicly funded systems, promote quality improvement, and increase provider leadership experience. Peer support strategies may be particularly important for providers of color who may face unique structural challenges when navigating early care and education systems and may therefore enhance racial equity. The considerations for planning a peer support initiative, the planning tool, and the examples from the field are intended to help state and local programs build upon and elevate providers’ expertise and knowledge to support the family child care sector.
