Preschool programs with family support services are center-based programs that support the cognitive and social development of children from low income backgrounds prior to kindergarten. These intensive programs usually include a combination of high quality preschool, parental education, and additional services such as home visiting, health, and family services. Examples of such programs include: Chicago Child-Parent Centers, HighScope Perry Preschool, and the Carolina Abecedarian Project. (author abstract)
