The Wisconsin Early Childhood Data System, set to launch later this year, will
draw on three state agencies' early childhood data to provide a comprehensive picture of young children and families. A new case study of WI ECIDS, from the
Early Childhood Data Collaborative
, highlights their model of interagency collaboration and makes recommendations for others working on data integration. One recommendation: building a data system that draws on agencies' existing systems, rather than requiring agencies to adapt to a completely new and untested model.
