"A good understanding of the foundations of psychological assessment and measurement is central both to applied and theoretical psychology. Having many years experience as an applied psychologist, trainer and university lecturer, Keith Coaley outlines in an accessible way the key ingredients of psychological assessment and provides case studies to illustrate their application, making this an ideal textbook for courses on the principles of psychometrics and assessment." "The book covers the nature of assessment, basic components, how tests are made, underlying statistics, reliability and validity, assessment of Intelligence, abilities and personality, non-psychometric approaches, as well as ethical and professional issues and modern developments. A final chapter explains how readers can construct their own tests. Wide-ranging case studies demonstrate the variety of contexts in which assessment is conducted. The author's clarity of writing and use of practical examples throughout will help students to apply these methods in practice with confidence as part of their studies on an array of courses."--Jacket
