Washington State Department of Early Learning (DEL) contracted with Thrive by Five Washington to facilitate and write this report. A collaborative group of key stakeholders helped develop this plan, which consists of actionable policy recommendations in seven high-level focus areas. Within each area are specific "next steps" that build on existing efforts to improve services and achieve measurable outcomes for children and families. Most of these recommendations are based on strategies and policies identified in Washington's Early Learning Plan (ELP) and the 2009 Recommendations to the Governor. This Birth to 3 Plan includes the following: (1) High-level recommendations and a small set of clearly prioritized, feasible and actionable policy recommendations that are necessary now to foster the optimal health and development of infants and toddlers; (2) A summary of the context for this plan, including the importance of "birth to 3" in early learning and what data tell us about infants and toddlers in Washington state; (3) A description of the process involved in this plan's development; (4) Identified outcomes anticipated to result from the implementation of these policy recommendations; and (5) A summary of financing options and considerations. This Birth to 3 Plan begins with the recommended policies and critical next steps that would continue to build a comprehensive birth to 3 continuum of services in Washington. Each key area contains a high-level policy recommendation followed by more concrete "next step" policy recommendations. Existing foundational elements on which the recommendations will build are also highlighted. Three appendices are included: (1) Second Substitute House Bill 2867; (2) Outcome Map; and (3) Early Learning Plan Guiding Principles.
