This guidebook presents a systems approach to planning, implementing, and evaluating mainstream programs for special needs learners in vocational education. (The guidebook itself models this system.) It is divided into four sections and numerous subsections (components) in this order: (1) Introduction (to mainstreaming, and the approach), (2) Program Planning (six components), (3) Program Implementation (twelve components), and (4) Program Evaluation (one component). Sections 2-4 comprise the steps required in beginning a new program or improving an existing one. Although they are presented in chronological order, many of the activities from different sections are interrelated and may occur simultaneously in actual practice. Each self-contained section presents a short introduction, recommended activities, and/or guidelines related to the topic. Selected resource materials, including samples, checklists, and flowcharts, are provided to illustrate and expand the concepts, approaches, and guidelines presented. These resource materials are suitable for reproduction. Each section was written to provide users with information on concepts, alternative approaches, and specific content. Flowcharts and/or checklists are included and can be used as administrative check-off sheets for critical steps in the various processes. (YLB)
