This paper presents a historical account of conceptual development at the intersection of American education and health. Beginning with early advancements from the Association for Supervision and Curriculum Development and the World Health Organization, the authors show the movement from early considerations of the codependency of health and education. The authors suggest that more than fifty years of theoretical innovations at the nexus of health and education culminated in the 2014 introduction of "Whole School, Whole Community, Whole Child" (WSCC). At the same time, the authors show that the trajectory of this movement was far from linear. In addition to explaining why WSCC is in many ways a critical revision of the social determinants model that serves today as a promising foundation of American school-based health, the authors examine opportunities and challenges that the pivot towards WSCC presents. Three particular areas are explored: assessment, funding, and collaboration.
