Every accredited MBA program requires course work in organizational behavior. In this course students learn that people approach problems with different perspectives based upon their culture, background, and values. Appreciation for this diversity is important for managers, and one can learn about it directly from one's own observations as well as from textbooks. The inclusion of people from different undergraduate schools and different geographic areas, as well as representation by minority races, genders, and international backgrounds, adds diversity to the student body.
Schools with a more diverse student body are given a higher rank.
