About the Society for Industrial and Organizational Psychology

Welcome to the Society for Industrial and Organizational Psychology’s (SIOP) Web site. We are pleased to introduce you to the field of industrial and organizational (I-O) psychology.

SIOP is the premier membership organization for those practicing and teaching I-O psychology. While an independent organization with its own governance, SIOP also represents Division 14 of the American Psychological Association and is an organizational affiliate of the Association for Psychological Science.

I-O psychology is a dynamic and growing field that encompasses workplace issues at the individual and organizational level. I-O psychologists apply research that improves the well-being and performance of people and the organizations that employ them. This involves everything from workforce planning, employee selection, and leader development to studying job attitudes and job motivation, implementing work teams, and facilitating organizational change.

If this is your first time visiting our site, we invite you to browse through the wealth of information and resources available to visitors and members alike. Thank you for your interest in SIOP.

I-O and the Employee Lifecycle:

Industrial-Organizational (I-O) psychology is the scientific study of the workplace. The knowledge base and scientific methods of psychology are applied to issues of critical relevance to business, including talent management, coaching, assessment, selection, training, organizational development, motivation, leadership, and performance.

Information regarding I-O psychology is organized in the framework of the "employment lifecycle." The information in each of the sections was developed to help you better understand how I-O psychology can benefit organizations in each phase of the employment lifecycle. Click either one of the links below or on the corresponding section of the lifecycle diagram to learn more about how I-O psychology is being applied to that aspect of the employment lifecycle.
