This guide provides a framework within which education authorities can work with teachers, parents, and community leaders to help young people learn the facts about Acquired Immune Deficiency Syndrome (AIDS) and Sexually Transmitted Diseases (STDs). It emphasizes the importance of education about human behavior and sexuality that is appropriate to a young person's particular stage of development and culture, and it is designed to help educational systems provide structured, sequenced, school-based approaches to the problem. The guide also describes how a school health education program on AIDS and STDs can be developed and integrated into existing curricula. The guide considers a number of issues that will need to be addressed by education authorities, such as the best way to enlist the support of parents, the need for special training of teachers, and ways of creating an appropriate classroom environment for discussion of sensitive subjects. Stressing the need for the curriculum to take into account the local culture and educational norms, the guide concludes that education about HIV and STDs is best given within a broad health education program. Appendices provide information on program evaluation methods, content options, teaching resources, and teaching strategies. (LL)
