This paper discusses public school-based child care facilities and the ways in which they benefit students, schools, communities, and children. It is argued that when there are child care centers in public high schools, teen-age parents whose children attend the facility are more likely to complete their education and less likely to become dependent on welfare. Schools benefit through lower dropout rates, improved parent education programs, vocational training for students, and increased performance from faculty who enroll their children in the facility. Communities profit from having a lower number of welfare participants; more efficient use of public health, nutrition, and social services; and more accessible high quality child care. The child care profession gains trained professionals, and all the children involved benefit from a high quality preschool education. Concerns relating to the continuity of child caregivers; community support; and planning, supervision, and coordination of resources are addressed. A list of 26 references is appended. (Author/GLR)
