This study examines the design and implementation of a leadership development program for students at SMAIT NFBS Bogor, an Islamic secondary school in Indonesia. Aimed at nurturing students' leadership potential within both academic and religious frameworks, the program integrates character education, experiential learning, and Islamic values. Through a mixed-methods approach combining surveys, interviews, and observations, the study evaluates the program's effectiveness in enhancing key leadership competencies such as communication, responsibility, and initiative. Findings suggest that structured, value-based leadership training can significantly contribute to students' personal growth and active participation in school and community life. The study offers practical recommendations for educators seeking to cultivate youth leadership in similar educational settings.
