Schools and teachers have been empowered with greater autonomy to make instructional decisions following decentralisation in education, both internationally and in the Chinese context. Thus, it is important to examine how teachers are involved in curriculum decision-making. Being the stakeholders who empowered teachers with autonomy, this study explored principals' perspectives of how teaching research group (TRG) leaders are empowered to take on a curriculum leadership (CL) role in secondary schools in China. A qualitative approach was employed and involved interviewing 10 principals and collecting the job descriptions of TRG leaders in 10 secondary schools in Taiyuan City, China. The NCR was pioneered in 2001 in 38 experimental areas (e.g., provinces, autonomous districts and municipalities) selected by the MoE, which aimed at prompting the implementation of NCR. Taiyuan City is one of the experimental areas (MoE, 2001). The findings demonstrated the necessity for empowering TRG leaders, as they were found to be less empowered and exhibited less awareness of enacting the CL role, especially for the national curriculum. In terms of the theoretical contribution of this study, it explicates the involvement of teacher leaders in CL at four levels (i.e., the school level, the classroom level, the social relationship level, and the personal level). This provides a reference for an in-depth understanding of teacher leaders' initiatives. In practice, the research findings are informative for entailing teachers with greater autonomy. This will ultimately prompt school development and thus broaden and add to the international body of knowledge on teachers' engagement in CL.
