This case study explores effective practices within a district's early care and education model. Interviews were conducted with eight parents of high-performing students and seven district ECE partners from Promise City. The results of this case study lead to the development of a model that comprises best practices within the (a) informal ECE subsystem, (b) formal ECE subsystem, and (c) intersection of the informal and formal subsystems. The model incorporates the best practices identified by Ma et al's. (2016) meta-analysis, as well as unique best practices found within Promise City. The findings highlight the importance of both informal and formal learning environments and actively working to bridge these environments.
