This research compares teachers' perceptions of principals' authentic-leadership dimensions, between collectivistic and individualistic cultures in the Israeli-Jewish (non-Arab) elementary schools. Culture will predict authentic-leadership dimensions with an individualistic tendency toward authenticity. 482 Israeli elementary school teachers (30% state-secular, 39% state-religious, 31% ultra-Orthodox) completed the Authentic Leadership Questionnaire and a demographic questionnaire. The results show that an internalized moral perspective was not predicted by culture, while self-awareness, relational transparency, and balanced processing were predicted by culture, associated with individualistic culture. This research strengthens the importance of culture for authentic-leadership and might help design culturally-sensitive principals' training programs; and may help principals improve schools' effectiveness in a culturally compatible manner.
