Occupational psychology involves the study of human behaviour in the workplace. It is also referred to as industrial or organisational psychology. Occupational psychologists are concerned with the performance of people at work and in training, and with developing an understanding of how organisations function and how individuals and groups behave at work. Their aim is to increase effectiveness, efficiency and satisfaction at work. They deal with issues and problems involving people at work by serving as advisors in a variety of organisations. They apply methods of psychology to issues of critical relevance to business, including talent management, coaching, assessment, selection, training, organisational development, performance, well-being and work-life balance. An honours undergraduate degree or a post-graduate conversion course accredited by the Psychological Society of Ireland (PSI) where psychology is the major subject is required. Completion of a recognised postgraduate training programme in occupational, industrial or organisational psychology is then necessary.
