This report provides a portrait of children who entered Head Start for the first time in fall 2009 and completed a year in the program in spring 2010. It also describes their family backgrounds and the classrooms and programs that serve them. Data are drawn from the 2009 cohort of the Head Start Family and Child Experiences Survey (FACES), a periodic, longitudinal study of program performance. Successive samples of Head Start children, their families, classrooms, and programs provide descriptive information at the national level on the population served; staff qualifications, credentials, and opinions; Head Start classroom practices and quality; and child and family outcomes. Previous FACES cohorts were initiated in 1997, 2000, 2003 and 2006.
