Abstract: One of the most important challenges of HR professional is to manage organizations talents, especially to ensure the right person for the right job. This paper presents an idea of identifying leadership quality in a person, which is a potential contribution that Data Mining (DM) could make within the Human Resource (HR) function in organizations,using association rule mining which is one of the most important techniques in the field of Data Mining. The original idea derives from attempts to deal with quantitative attributes in a database, where subdivision of the quantitative values into crisp sets would lead to over or underestimating values. The concept of Fuzzy will help to overcome the problem by allowing partial memberships to variable values.
