This guide is designed to assist high school teachers in their preparation of lessons covering the Selective Service System. The guide is organized into seven chapters. Chapter 1 describes Selective Service as it exists today, explains the registration process and its role in the national defense system, details who must register, and emphasizes that registration for such persons is a prerequisite for federal student loans, job training programs, and appointment to federal employment. Chapter 2 discusses the history of compulsory military service to meet national emergencies, the first draft laws, The Selective Training and Service Act of 1940, and women and the draft. Chapter 3 reports on draft laws during World War I and the 1948 Selective Service Act. Chapter 4 reports on the organization, functions, objectives, and structures of the Selective Service System. Chapter 5 discusses Selective Service classification, the process of determining who is available for military service and who is deferred or exempt from such service (no classification actions are being taken at this time, because no one is being drafted). Chapter 6 focuses on the responsibilities and duties of local and appeal boards. Chapter 7 addresses the Selective Service System claim and appeal process in the event of a resumption of induction authority. Each chapter is accompanied by a summary of important teaching points and questions and answers. A glossary of terms and a resource list are included. (LL)
