Competence-based assessment has become the norm since this best-selling book was first published. It is now viewed in most organizations as essential that workplace efficiency is measured by occupational standards - but this can seem a complex area for many trainers. This revised second edition provides trainers and students with a critical guide to the key principles, methods, implications and benefits of competence-based techniques. Drawing from her own extensive experience, Shirley Fletcher offers practical and authoritative guidance for all trainers and managers using, or wanting to use, this form of work-based assessment. In Part One she explains what competence-based assessment is, its purposes and uses, and looks at the different systems in existence. Part Two gives advice on implementation and examines in particular: setting performance criteria; collecting evidence of competence; matching evidence against standards or criteria; occupational; and behavioural competence.
