This workbook, one of six professional development manuals prepared by experienced Adult High School (AHS) instructors, is designed to assist the instructor setting up and operating a General Education Development (GED) classroom. A pretest and posttest appear first. Each of the seven units begins with a list of objectives and then provides instructional material. Unit 1 provides information on the background, curriculum, classroom exams, grading system, course prerequisites, half-credit courses, and diploma requirements for AHS. Unit 2 examines the need for classroom consistency, ways to inspire students to succeed, how to help students make the transition from public high school to AHS, and how to meet the challenges of course content and accountability requirements. Unit 3 explores the need for adequate record keeping and the importance of conveying to the students what is expected of them and what it means to teach in a self-paced program. Unit 4 identifies the skill areas on the High School Competency Test (HSCT) and Florida Comprehensive Assessment Test (FCAT), suggests supplemental HSCT teaching resources, test timelines, and suggestions for student preparation. Appendixes include sample educational resources for the AHS classroom, pretest and posttest answer keys, instructor self evaluation, and student evaluation. (YLB)
