This case study of the California Physical Education-Health Project (CPE-HP) provides a portrait of what physical education can and should be and describes CPE-HP’s role in achieving the vision. Physical education is more than physical activity; it is about students learning how to move. It supports all students in being active and healthy, which contributes to their achievement in school. The case study showcases how CPE-HP is building capacity for standards-based physical education across the state through developing teacher leaders who lead professional development for other teachers. In addition to leading CPE-HP professional development, these teacher leaders act as ambassadors and advocates for standards-based physical education programs in their schools and districts. Whereas CPE-HP supports the development of both health education and physical education, this case study is exclusively on physical education.
