This book provides a comprehensive and state-of-the-art overview of simulation development, technologies, and implementation, including real-world examples and results followed by a preview of what’s on the horizon that will further revolutionize the industry. More than a handful of books have been written on the use of simulations for training purposes, but this book focuses solely on simulations in employee selection contexts (e.g., hiring, promotion), making it a truly unique and valuable resource for both practitioners and academics. The science and practice of employee selection has advanced at a steady pace over the past two or three decades. However, recent advancements in both technology and assessment methods have been the catalyst for an evolutionary leap in the use of simulations in this area.
