Head Start and Early Head Start are federally funded programs that promote the development of low-income children from birth to age 5. Head Start serves children ages 3 to 5 and their families, while Early Head Start focuses on pregnant women and children from birth to age 3. The mission of Head Start is to enhance children's social and cognitive development through educational, health, nutrition, and other services to prepare them for school. Head Start curricula should be adapted for each group and support each child's development, while integrating educational aspects of health and providing opportunities for children to develop relationships and feelings of competence.
