The SLDS Early Childhood Integrated Data System Toolkit was designed for use by any state regardless of where it is in the process of developing an ECIDS. The Toolkit has seven components: (1) Purpose and Vision, (2) Planning and Management, (3) Stakeholder Engagement, (4) Data Governance, (5) System Design, (6) Data Use, and (7) Sustainability. Each component has a set of key indicators that describe the "what" is ideal for the specific component and each indicator has elements that discuss "how" to accomplish the "what" outlined in the indicator.
