Concluding a two-year review and revision process supported by the American Cancer Society and conducted by an expert panel of health education professionals, this second edition of the National Health Education Standards is the foremost reference in establishing, promoting, and supporting health-enhancing behaviors for students in all grade levels. These guidelines and standards provide a framework for teachers, administrators, and policy makers in designing or selecting curricula, allocating instructional resources, and assessing student achievement and progress; provide students, families, and communities with concrete expectations for health education; and advocate for quality health education in schools, including primary cancer prevention for children and youth.
