The document summarizes several models of school health programs, including the three-component model, eight-component model, and full-service schools model. It describes the key elements and features of each component in the different models. The three-component model includes health education, health services, and a healthful environment. The eight-component model, from the CDC, expands on this to include additional elements like physical education, nutrition services, counseling, and parent/community involvement. The full-service schools model envisions the school as a center providing a wide range of health, social, and family services through collaboration with community agencies.
