The use of tests and assessments in employment-related decision making has the potential to benefit organizations and individuals. However, their use is frequently criticized because of their adverse potential for bias and unfairness. Although issues pertaining to employment testing, bias, and unfairness are extensively researched and written about, previous work has predominately focused on perspectives from the United States. Therefore, the goal of this handbook is to provide a global examination of ideas and issues pertaining to bias and unfairness in employment testing. Specifically, this text details perspectives from twenty-three countries spanning six regions of the globe, on the definition, assessment, and reduction of bias and unfairness in employment testing. In doing so, this work fills a critical gap in the knowledge and information available to employment testing scholars and practitioners who conduct research and practice in an increasingly globalized world.
