The changing global and local circumstances and shift for democracy posed particular problems for school administration and leadership and made it difficult for principals to fulfil leadership responsibilities in schools alone. Hence principals require the assistance of all stakeholders in the school, and teachers in particular, to work together as a team and share the diverse leadership load for the improvement of schools. Thus, leadership in schools needs to be shared and distributed in a collaborative manner among teachers and principals working as a group to accomplish the primary objective of their schools, which is to improve learners’ achievement. For this idea to be embraced, I suggest it may require an urgent need for advanced knowledge and understanding of teacher leadership in schools, among teachers and principals, if schools are to thrive. This research studied the phenomenon of teacher leadership at a public rural school in the Ohangwena region of Namibia. It explored the teachers’ experiences of their leadership roles, and specifically the challenges inherent within the practice of teacher leadership in a school. A qualitative interpretive case study was conducted, employing document analysis, semi‐structured interviews and observations to produce data with regard to teachers’ experiences of their leadership roles, challenges inherent within its practice and possible strategies to promote teacher leadership. The analysis and the triangulation across the data sets suggested that teacher leadership existed in the case study school where it appeared in four different areas of leadership practice. These areas of leadership practices (Grant, 2008, p. 93) were, for example, in the classroom, outside the classroom in curricular and extra‐curricular activities, in school‐wide leadership development and between other neighbouring schools in the community. The school had a view of teacher leadership which was strongly located within the classroom and outside the classroom in curricular and extra‐curricular activities where teachers worked and interacted with their colleagues and learners. Teacher leadership was severely limited in the area of whole school development and almost non‐existent in the area outside the school between teachers across neighbouring schools, at circuit or district level and in the community. The study suggested that the nature of teacher leadership in the case study school was a restricted form of teacher leadership (Harris and Muijs, 2005) due to a range of factors which impeded its practice. The factors were, for example, a lack of involvement of all teachers in whole school leadership and school‐wide decision‐making. Other factors were limited time for teachers in the school, a lack of leadership development amongst the principal and teachers as well as resistance for teachers to leadership in the case study school.
