The purpose of this study was to determine the degree to which Kouzes and Posner's Transformational Leadership Model is being practiced by school principals as perceived by their teachers in Jordanian schools. Means, standard deviations, t-tests, and one-way analysis of variance (ANOVA) were utilized in this study. Results indicated that transformational leadership is being moderately practiced and applied by Jordanian principals. Furthermore, statistical results indicated that gender and school type had an influence on teachers' perceptions in favor of female teachers and basic schools respectively. Finally, there were no significant differences among the three experience level groups of teachers (new hiring, middle career, and long experience) in their perceptions of each dimension of Kouzes and Posner's model.
