When designing a curriculum, researching lessons, or providing quality information in a health class, where does one even start? Many people recommend starting by looking at professional organizations. There are several professional organizations or groups in the United States that focus on school health. For this article, the authors have chosen the three most well-known organizations and special professional associations (SPA) that contribute to producing some of the best resources, tools, and best practices in school health education: SHAPE America - Society of Health and Physical Educators of America, the Society of Public Health Educators (SOPHE), and the Centers for Disease Control and Prevention (CDC), specifically Healthy Schools and the Division of Adolescent School Health (DASH). This article briefly describes each of these three health organizations, along with their guiding frameworks, current research and survey database collections systems, resources and tools, professional development and conference opportunities, grant and fundraising opportunities, and membership benefits, leadership, and awards.
