This study aimed to examine the influence of transformational leadership and personality on organizational citizenship behavior (OCB), with organizational culture as a moderating variable, among teachers and administrators of Islamic Boarding Schools in Bandar Lampung. Study Design: A quantitative, cross-sectional study using a census approach. Place and Duration of Study: Islamic Boarding Schools in Bandar Lampung, Indonesia. Methodology: Data were collected from 111 respondents, consisting of teachers and administrators, through a structured Google Form questionnaire. The study employed a partial t-test and moderation regression analysis (MRA) using IBM SPSS version 25 to test direct effects and moderation effects. Results: The findings supported all proposed hypotheses. Transformational leadership had a significant positive influence on OCB (p < 0.05). Personality also had a significant positive influence on OCB (p < 0.05). Furthermore, organizational culture significantly moderated the relationship between transformational leadership and OCB, as well as between personality and OCB (p < 0.05 for both moderation effects). Conclusion: Transformational leadership and personality both enhance OCB, and these effects are strengthened in the presence of a supportive organizational culture. It is recommended that teachers and administrators focus on open and transparent communication, establish regular discussion forums, provide feedback channels, implement appreciation systems, and encourage intellectual capacity development through continuous training.
