Conflict is an inevitable fact of organizational life. In educational organizations, conflicts are also inevitable and likely to occur because the primary input is human and human interactions are so intense in such organizations. This study aimed at investigating the relationship between school administrators' conflict management style preferences and their personality traits. In this study, the data related to school administrators' conflict management style preferences was gathered through Rahim's Organizational Conflict Inventory (ROCI) (1983). In order to reveal school administrators' personality traits, Five-Factor Personality Inventory (5FKE) which was developed by Somer, Korkmaz and Tatar (2002) was employed. 5FKE and ROCI II were conducted to 89 school principals and 122 deputy principals working at state schools in Kastamonu. In this study, it was found that there are statistically significant correlations between school administrators' personality traits and their conflict management style preferences.
