For four years ending in 2022, the nine nonprofits in the Detroit Early Childhood Education Support Initiative worked with and on behalf of over 100 early childhood centers through whole child and the whole family programs ranging from healthy living and nutrition to parent and caregiver engagement and advocacy.  The case study details how their cohort — supported by nonprofit Mathematica — worked to collectively strengthen the early childhood system, improve coordination with families and providers, and leverage each other’s programming to more holistically serve the needs of children and families. The nine nonprofits in the initiative were ACCESS, Children’s Center of Wayne County, Inc., Detroit Educational TV, Detroit Hispanic Development Corp., Keep Growing Detroit, Learn Early, Living Arts Detroit, Mothering Justice and the National Kidney Foundation.
