The Wisconsin Early Childhood Integrated Data System integrates data from the state Departments of Children and Families, Health Services, and Public Instruction. The system links, collects, and monitors early childhood data from 11 state programs. The state engaged in an inclusive planning process to design the system, which, although not an integrated data warehouse, provides for data sharing among relevant state agencies. The system also has strong privacy protections, including an overarching memorandum of understanding and individual data-sharing agreements from the Departments of Children and Families, Health Services, and Public Instruction, which are used with each interagency data-sharing project.
