Teacher leadership has been widely discussed in terms of its definition, concept, frameworks, and models. Generally, teacher leadership encompasses the concept of power and influence. This paper has focused on four teacher leadership frameworks and models from Moller (2001 &, York-Barr and Duke ( 2004), Muijs and Harris (2003), and Angelle (2017). A literature review was conducted on teacher leadership definitions and concepts, the frameworks and models were collated, and common aspects were identified. The paper also critically analysed the effectiveness in developing and implementing teacher leadership practices. This paper concludes with further understanding of recognising teachers as leaders throughout the school organisation. This paper aims to provide a reference for school leaders to adapt teacher leadership that is suitable for the schools' context and capacity.

Teacher leadership significantly promotes development and efficiency at schools. However, the practice of teacher leadership is slammed with challenges that impact its progression and effective implementation in schools. Therefore, the present study focused on the key terms, problems, and obstacles of teacher leadership based on domestic and international works of literature on teacher leadership practices. The study discussed the notion of teacher leadership before it addressed the challenges in the practice. Hence, the present paper helped school leaders to establish teacher leadership tasks in schools and help researchers to carry out more studies on teacher leadership.
