The health services area is a major aspect of the comprehensive services provided by Head Start and Early Head Start (HS/EHS) programs. The Head Start Health Manager Descriptive Study was designed to improve our understanding of this important component of Head Start by providing a current snapshot of health-related activities and programming within HS/EHS programs, describing the context in which the health services area operates, and identifying the current needs of health managers and other staff as they work toward improving the health of HS/EHS children, families, and staff. To accomplish this objective, the study designed and fielded a short online survey for HS/EHS program directors and a more in-depth online survey of the HS/EHS health mangers. All directors of HS/EHS programs in operation during the 2012-2013 program year were invited, including American Indian and Alaska Native programs and Migrant and Seasonal Head Start programs. In addition, semistructured interviews were conducted with a small number of health managers, teachers, family service workers, and home visitors. The survey data were also linked to administrative data from the Head Start Program Information Report, as well as county-level indicators and other geocoded data. (author abstract)
