Mobiliser teachers are trained and professional teachers who play a strategic role in leading learning and improving the quality of education in schools. Although teacher mobilisers have become a reference point for positive changes in education in Indonesia, their presence is still considered by many to have not contributed to schools. However, there are various different assessments regarding the existence of mobiliser teachers. A number of groups believe that the effectiveness of mobiliser teachers is still low, while others believe that mobiliser teachers have the potential to successfully advance learning in schools. Apart from that, research on mobiliser teachers is still very minimal in Indonesia so it does not provide comprehensive knowledge about the contribution of mobiliser teachers in Indonesia. This research aims to explore the role of mobiliser teachers in leading learning and driving learning communities and their impact on student learning. A qualitative approach was used in this research and a total of 13 teachers were interviewed. The findings of this research indicate that mobiliser teacher leadership is instructional leadership that effectively leads learning and mobilizes the teacher community in the school and region and contributes to student learning.
