This thesis investigated the leadership approach associated with sustained improvements in academic performance among principals heading National Strategy for Learner Attainment (NSLA) schools. The research problem addressed the leadership practices and personality traits that characterised the leadership approaches of principals heading high schools which have achieved long-term academic improvement amongst the schools undergoing the NSLA interventions. The main research question was: What leadership practices and personality traits characterised the leadership approaches of principals heading schools who have achieved long-term academic improvement amongst the schools undergoing the NSLA interventions? Thereafter, four subsidiary research questions guided this research. Firstly, what were the leadership practices of principals in selected successful NSL schools? Secondly, what personality traits characterised these principals? Thirdly, what learning and teaching challenges did principals heading these schools face? Lastly, how did these principals address the learning and teaching challenges in these schools? The literature and past research supported and provided information that leadership at schools plays a pivotal role for teaching and learning to be successful. However, the literature does not prescribe a specific leadership approach, but recommended a contingency leadership approach. The contingency leadership approach was used as the theoretical framework for this study. This approach recognises that there is no single preferred style of leadership and that the situational context must be taken into account for leadership to be effective. The study was guided by the qualitative methodological paradigm which is embedded in the interpretivist approach in order to develop rich and in-depth descriptions and meaning, feelings and experiences gathered from respondents.enSecondary School PrincipalsNational Strategy for Learner Attainment (NSLA)Leadership Theories and ApproachesAcademic PerformanceContingency TheoryThesis
