Membership Society of Industrial and Organizational Psychology

SIOP is the premier membership organization for those practicing and teaching I-O psychology. While an independent organization with its own governance, SIOP is also a division within the American Psychological Association and 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.
