A seminal text on the psychometric approach to personnel selection, the sixth edition of Personnel Selection has been fully updated and expanded to address the challenges and changes in todays workplace. Written by a noted expert, with more than 30 years experience in the field, this edition focuses on cutting-edge topics and new areas of research, while also providing a complete introduction to theoretical principles and practical advice. New topics in the sixth edition include the influence of social networking sites, new research in adverse impact, age differences and stereotypes, distribution of work performance, and the problems of selecting new employees using research based on incumbent employees. The book also questions established truths and beliefs, re-examining issues that have been characterized historically as not a problem, including differential validity, over-reliance on self-report, and faking good. It contains expanded discussion of research and practice in the US and internationally, while maintaining the definitive coverage of UK and European selection approaches. The text includes a variety of helpful pedagogical tools, such as technical and statistical boxes, simplified figures and tables, research agenda boxes, key point summaries, and key references. Comprehensive yet accessible, this text arms professionals, trainees, and students with the skills and information they need to navigate the complexities of personnel selection today.
