Head Start is a national program that promotes school readiness by enhancing the social and cognitive development of children through the provision of educational, health, nutritional, social, and other services to enrolled children and families. The Head Start program provides comprehensive child development services to economically disadvantaged children and families through grants to local public and private nonprofit and for-profit agencies. This report includes key information on the Head Start Family and Child Experiences Survey 2014-2018 (FACES 2014) study design; in addition, a set of data tables presents descriptive statistics for the characteristics of programs, centers, classrooms, and teachers serving Head Start children and families in spring 2017. The purpose of this report is twofold: (1) to provide information about the FACES study, including the background, design, methodology, measures, and analytic methods; and (2) to report detailed descriptive statistics and related standard errors in a series of tables on the programs, their staff, and classrooms. The data provide descriptive information from classroom observations and staff surveys about Head Start's efforts to help children and families meet their goals, and local efforts to meet the Head Start Program Performance Standards.
