Industrial and Organizational Psychology

Study methods to improve the work lives of employees and increase business performance.

What is Industrial and Organizational Psychology?

Industrial and Organizational (I-O) psychologists use science and statistics to solve workplace issues and to help workers and businesses thrive.

Our program is committed to preparing students for the current issues facing the workplace today. As such, our I-O curriculum includes examining inequities, historical and current, facing employees. The combination of I-O practice and an employee-centered justice approach enable students to move beyond the socio-political trends of the day and identify the root cause of problems facing employees and organizations today.

I-O Psychologists help organizations by:

  • selecting and training the best employees
  • determining how to retain and recruit talented employees
  • learning what stressors make jobs difficult
  • developing great organizational leaders
  • understanding work motivation
  • studying how to make workplaces safer
  • and by analyzing what can help organizations grow, change, and adapt

Whether you’re at the start of your career as a psychologist or looking to further expand your training, consider this online degree from Park University.
