||The objective of the National Survey of Early Care and Education (NSECE) is to document the nation's current utilization and availability of early care and education (including school-age care), and to deepen understanding of the extent to which families' needs and preferences coordinate well with provider's offerings and constraints. The experiences of low-income families are of special interest as they are the focus of a significant component of early care and education/school-age (ECE/SA) public policy. The NSECE calls for a nationally-representative sample including interviews in all fifty states and Washington, DC. Data are scheduled to be collected December 2011-May 2012. The final NSECE design includes four survey components and four related questionnaires: (1) The Household Survey conducted with a parent or guardian of a child or children under age 13. Eligible respondents are to be identified through the Household Screener, and information collected about every child under age 13 in each sampled household, including all the regular ECE arrangements. Data include 17,512 interviews with adults in households with children under age 13; (2) The Family, Friend, Neighbor and Nanny (FFNN) Survey conducted with individuals who care in a home-based setting for children under age 13 who are not their own (and who do not appear on an administrative list of ECE/SA providers). Eligible respondents are to be identified through the Household Screener, and estimated data will include approximately 5,000 completed interviews with FFNN providers; (3) The Formal Provider Survey conducted with directors of ECE/SA providers who can be identified from administrative lists such as state licensing lists, Head Start program records, or pre-K rolls, including regulated or registered home-based providers who appear on state-level administrative lists. Data will include interviews with 18,800 programs; (4) The Workforce Provider Survey conducted with one staff member from each of the sampled formal providers after each Center-based Provider interview is completed. Data will include interviews with workforce members from 10,800 programs. The NSECE contract also includes an option for States to contribute to the study to supplement samples in order to conduct state-level studies of populations of interest. Preparatory work for the NSECE was accomplished through the Design Phase of the National Study of Child Care Supply and Demand.
