This study identifies differences in the scores of Jordanian and American business students on the Keirsey Temperament Sorter personality test. The test was administered to 137 students at the University of Jordan in Amman, Jordan, and Washington College in Chestertown, Maryland. The research results show that, although there are significant differences in personality traits in two of four categories, there are more similarities than differences between the traits identified by these groups of students. This indicates that the personalities and temperaments of business students in Jordan and the United States are not remarkably different.
