Abstract Character development is a fundamental aspect of primary education that focuses not only on academic achievement but also on cultivating students’ positive attitudes, values, and behaviors. In this context, Guru Penggerak (Teacher Leaders) hold a strategic position as instructional leaders who promote student-centered learning environments and character development. This study aims to analyze the role of Guru Penggerak in shaping students’ character at SD Negeri 168 Palembang and to identify the strategies and supporting factors involved in its implementation. This study employed a qualitative approach with a case study design. Data were collected through observation, in-depth interviews, and documentation involving Guru Penggerak, teachers, the school principal, and students as sources of information. The findings indicate that Guru Penggerak contribute to students’ character development through role modeling, habituation of positive behavior, student-centered learning, reinforcement of discipline and responsibility, and collaboration among school members. These practices contribute to the development of students’ religious character, discipline, independence, responsibility, and mutual cooperation. The study highlights the importance of strengthening the role of Guru Penggerak as agents of educational transformation in establishing a sustainable school culture that supports students’ character development.
