This study aims to analyse the transformational leadership of school principals in improving educational quality through extracurricular activities, with case studies at SMA Negeri 1 Abung Semuli and SMA Negeri 1 Abung Barat, North Lampung Regency. The research focuses on three main aspects: (1) the characteristics of transformational leadership of school principals, (2) the strategies applied in developing extracurricular activities, and (3) the impact of transformational leadership on educational quality. This study employs a qualitative approach using the case study method. Data validity was tested through source and technique triangulation, while data analysis used the interactive model of Miles and Huberman, which includes data reduction, data presentation, and conclusion drawing/verification. The results of the study indicate that both principals applied the four dimensions of transformational leadership, idealised influence, inspirational motivation, intellectual stimulation, and individualised consideration, with contextual implementation in accordance with the character of the school. The resulting impacts include providing opportunities for participation in the change process, fostering a collaborative culture and positive school climate, a correlation between academic achievement and involvement in extracurricular activities, and an improvement in the school's reputation and appeal. This study affirms that the transformational leadership of school principals plays a significant role in optimising extracurricular activities as a means of enhancing educational quality.
