This report describes what selected state officials and local child care providers identified as (1) the benefits to integrating funding from federal Head Start, CCDF, and state Pre-K programs and partnering with other providers; (2) factors that adversely affect integration and partnering; and (3) ways these adverse impacts were mitigated. To gather information about the factors that affected integrating funds and partnering, we conducted 24 interviews with state officials and local providers in four states (Colorado, Maryland, Washington, and West Virginia). We initially identified states using recommendations from HHS, state officials, and child care stakeholder groups. The final list of states we selected was based on the following criteria: (1) participation in HHS's EHS-CCP grant program; (2) experiences with partnering among early care and education programs; (3) variation in licensing standards; and (4) differences in state income eligibility levels for CCDF. In each state, we selected 2 to 5 providers for interviews, also based on recommendations of state officials or providers that were integrating funds or partnering as part of their provision of early care and education services. We also conducted interviews with HHS, Education, and representatives of child care stakeholder groups. We also reviewed relevant federal laws and regulations, agency documentation, and literature. Enclosure I of this report provides a detailed presentation of our work and findings in a briefing to our requesters on May 19, 2016. (author abstract)
