This resource focuses on how early childhood leaders and coalitions are designing and implementing plans to sustain progress and achieve goals developed through Race to the Top--Early Learning Challenge (RTT-ELC) as Federal funding ends. Although each State is unique, and State approaches will vary, some sustainability themes and processes are relevant to all States. Examining these themes and processes can guide State sustainability work. This document addresses core questions and issues regarding sustainability planning and implementation. The questions and issues were recently identified by State leaders, and the answers are culled from recent resources on sustainability planning and implementation. (author abstract)
