Heads of Secondary Schools (HSS) grapple with a multitude of challenges that directly influence their job satisfaction, subsequently affecting their overall job performance. This study delves into the experiences of HSS in Tanzania, aiming to identify strategies for improving their job satisfaction. Employing a mixed methods research approach, the study blends qualitative and quantitative data collection techniques. A cross-sectional survey was conducted to gather quantitative data, complemented by interviews and focus group discussions to capture qualitative insights. The study encompassed 78 HSS, comprising 20 from private and 58 from public secondary schools. Quantitative data were analyzed using the Statistical Package for Social Sciences (SPSS), while qualitative data were thematically analyzed. Insights from HSS underscored the importance of introducing compensation benefits, providing essential leadership training, addressing political interference in academic matters, and granting autonomy in decision-making to enhance job satisfaction. Based on the study findings, appropriate recommendations were provided.
