This document explains the Youth Training Scheme (YTS) in Great Britain. It is intended for YTS managers, coordinators, and tutors but may also be useful to curriculum and staff developers at colleges and training organizations. The manual begins with an introduction that gives the background and rational for the YTS, and it ends with a 60-item reference list. In between, four sections offer information and advice on aspects of the design framework of YTS. The section entitled Inputs describes the training plan, training agreement, competence objectives, work experience, and off-the-job training and education that Approved Training Organizations (ATOs) must provide all YTS enrollees. The section entitled Training Processes explains the processes (selection, induction, assessment, guidance, review, and negotiation) that ATOs must implement for enrollees. The section entitled Certification states that all outcomes of the program (competence in a job and/or range of occupational skills; competence in a range of transferable skills; ability to transfer skills and knowledge to new situations; and personal effectiveness) lead to certification. A section called Evaluation, Development, and Quality explains how ATOs should conduct formative and summative program evaluation, develop curriculum and staff, and ensure quality in training. All chapters include a self-evaluation checklist that allows readers to test their understanding of the chapter. (CML)
