This study embarks from the great and huge responsibility of teachers nowadays especially the IRT (Islamic religious teachers). As the role model of students, they play an important task especially in producing the good Muslim character. Therefore, their job not only focuses on the content of subject but becomes wider in scope, more than other teachers in molding a human. For this, the mind faculty plays an important role. Many studies have proved that people's belief and how they perceive themselves can influence their personality and make them be a center of attention. The past research findings have shown that teachers need to have the PSC (positive self-concept) to help them become a successful role model and produce the great Muslim character in the future. Thus, this study seeks to look at the need of PSC in IRT as a role model. This study is a conceptual paper which is based on the analysis of document method. The paper will discuss the role of IRT, the PSC and the needs for teachers, and the influence of teachers' PSC on students' behaviour. Due to current scenario of social ills, the IRT responsibility of educating and molding the good character of Muslim students becomes much more challenging. Therefore, in order to make sure the vision is accomplished, IRT must build the PSC in themselves first.
