The staff involvement (SI) and family and community engagement (FCE) components of the CSPAP framework constitute the support system for program implementation and sustainability. These components embody the essence of the framework because they focus on the coordination and synergy needed for a successful program, and such attributes are the hallmark of multicomponent approaches to school-based health promotion. But what does it take to galvanize school staff, families, and communities in a collective effort to bolster quality physical education and promote and increase the physical activity (PA) of children and adolescents? In this article, the authors summarize research on SI and FCE, particularly over the past decade. While research on these CSPAP components is still in its emergent stages, we identify key findings to date and suggest strategies for translating research to practice. It is our hope that this article will provide school PA leaders (PALs) and physical education teacher educators with actionable ideas to more fully leverage the CSPAP support system.
