To maximise the effectiveness of secondary school education, teacher leadership has to be implemented to enhance the performance of teachers. Therefore, this paper described some major types of educational leadership that could boost teachers’ performance, and help to provide a superior learning environment for students that will lead the way in secondary school education. This study, which is hinged on the Performance causes Satisfaction and the Managerial Grid theories chose six secondary schools in Oshimili South Local Government (LGA) of Delta State, Nigeria for analysis. The researchers employed a descriptive survey research design with a population and sample size of 111 and 86 respectively, while the questionnaire was used as the instrument for data collection. Bar Charts and simple percentages were used to analyse the data. Findings showed that the attributes of conflict management ability, good role model, and display of humility in teachers’ leadership affect performance significantly, and that there is a correlation between laissez-faire leadership style and teachers’ performance in the sense that this style of leadership negatively impacts on teachers’ performance. Based on the findings, it was concluded that teacher-leaders should vary their approach of leadership to achieve high-performance levels without undermining other teachers’ satisfaction levels. The recommendations include that the Democratic type of leadership by teacher leaders should be encouraged in Secondary schools because it is encompassing; that schools may implement a teacher leadership model as a strategy to downsize and cut costs for the school. In most cases, distributing administration among the teachers could reduce overall personnel costs, among others.
