This handbook presents management techniques, program ideas, and student activities for building comprehensive secondary career guidance programs. Part 1 (chapter 1) traces the history of guidance to set the stage for the current emphasis on comprehensive programs, summarizes four representative models for designing comprehensive programs, and cites additional models. Part 2 (chapters 2-7) identifies specific student practices for building a comprehensive program. Each chapter is organized into (1) narrative, with definition, rationale for use, summary appraisal of practices, and full description of an illustrative practice; (2) ten abstracts of practices, showing range, types available, costs; (3) additional practices; and (4) references. Chapter 2 focuses on curriculum-based practices--a broad approach to delivering career guidance practices. Chapters 3-5 present individual practices geared primarily to one developmental area. Titles are Self-Understanding and Occupational Knowledge Practices; Career Exploration and Decision-Making Practices; and Placement, Follow-Up, Follow-Through, and Employability Skills Practices. Chapter 6 addresses the needs of women and special sub-populations. Chapter 7 concerns computer-based career guidance practices. Part 3 (chapter 8) discusses the implementation of programs and practices under these topics: change agent roles for counselors, a seven-step strategy for effecting change, and a review of roadblocks to change.
