The Early Childhood Advisory Council (ECAC) acknowledges that data is a critical asset as it supports evidence-based decision-making and drives informed action. The ECAC is committed to implementing inter-agency data governance structure and processes to support the South Carolina (SC) Early Childhood Integrated Data System (ECIDS) and its linkage to future longitudinal data systems. Participating programs in the SC ECIDS seek to develop a common understanding of early childhood data that is collected across South Carolina and will work to resolve data issues to achieve higher data quality.
