Identifying the voluntary activities, programs, and services that children and families use during students' out-of-school time as primary supports, this self-study guide provides a framework for developing primary support programs that allow school-aged children and adolescents to develop physical, cognitive, social, and emotional skills. The guide details four key program components and describes basic qualities within each component that "good enough" primary supports for school-age children and youth should provide. The guide also provides indicators at three levels and questions that can assist staff and management to set goals and work toward improvements over time. The four components of program quality are: (1) safety, comfort, and belonging; (2) positive social interactions and relationship; (3) activities and programming that promote healthy development; and (4) organizational and administrative competence. For each program component, the key indicators of quality are summarized, with each indicator accompanied by a series of discussion topics/questions. Space is available to record how the organization is doing and what improvements might be considered. The guide concludes with a list of 19 recent publications of Chapin Hall for those planning, managing, funding, and working in programs for youth. (KB)
