Iowa’s Integrated Data System for Decision-Making (i2d2) is an integrated data system, overseen by a governing board and coordinated among health, social service, and education agencies, that comprehensively identifies and addresses the needs of Iowa’s young children and families. Since launching in 2016, i2d2 has been used to better understand early childhood service utilization and the early childhood workforce, including supporting a comprehensive statewide needs assessment as part of a Preschool Development Grant B-5.
