Guidelines to help schools and communities in New York implement or improve a Comprehensive School Health and Wellness (CSHW) program are outlined in this manual. Based on 8 components and 11 interrelated conceptual areas, the 811 Grid offers a framework for assessing current efforts and for planning strategies to improve school/community health. Key features include school collaboration with community resources and shared responsibility. The five-step process involves: (1) organization of an advisory committee; (2) identification of supporting efforts; (3) assessment of current supporting efforts; (4) statement of objectives and development of an action plan; and (5) evaluation and reassessment. Appendices, which comprise two-thirds of the document, include: the components of the CSHW program with questions and suggestions (e.g., healthful school environment, health services, physical education, food services, etc.); blank 811 grid; 811 grid with sample questions; 811 grid analysis; an action plan; and guidelines for establishing an advisory committee.
