Do you know yourself? Really? Are you a good judge of others? These questions are at the heart of personality assessment. And whether you are applying for a job, trying for promotion or looking for a change of direction, it is likely that you will be required to complete a psychometric test or some kind of personality profile at some time. This book examines the background of such assessments and the theories behind them and offers the reader the chance to carry out a series of far-reaching tests. Psychometric testing is a huge global business and this book shows, through practical example, how to achieve deeper insights into the ways we function and behave.
