How young people spend their out-of-school time is a longstanding concern of the public and of organizations and individuals that provide the voluntary activities, programs, and services for children and families. Meaningful participation in primary support programs by young people, can support healthy development, foster self-direction, and help build identities as individuals who believe that they can and should contribute to their communities. This self-study guide is intended to help primary support organizations that serve young people aged six to eighteen years consider how their programs contribute to healthy development and how those contributions might be enhanced. The guide offers four key program components and describes basic qualities within each component. It can help staff set goals and work towards improvements.
