Abstract: This study investigated the impact of teachers’ supervisory practices on students’ academic performance in public secondary schools within the Mpwapwa district, Tanzania. Guided by the Servant Leadership Theory and pragmatism research philosophy, the study employed a mixed-methods approach and a cross-sectional research design. The study involved 243 participants, 233 were teachers and 10 heads of schools who were selected using both stratified random and purposive sampling techniques. Quantitative data were collected using structured questionnaires from teachers, while qualitative data were gathered through interviews with heads of schools. Quantitative data were analyzed using descriptive statistics, and multiple regression analysis using Statistical Package for Social Sciences (SPSS version 27), while qualitative data were analyzed thematically to capture insights into instructional supervision practices and their influence on teachers’ instructional quality and students’ learning outcomes. The findings revealed that teachers’ supervisory practices were generally high, with regular classroom observations, timely feedback, performance appraisals, and moderate professional development support contributed positively to students’ academic outcomes. Regression results indicated a strong and statistically significant relationship between teachers’ supervisory practices and academic performance (R = 0.727, R² = 0.528, p < 0.001), suggesting that effective school-based instructional supervision explains over 50% of the variance in students’ learning outcomes. The study concluded that structured and consistent instructional supervisory practices play a critical role in enhancing students’ learning outcomes. Based on these findings, the study recommends that school management prioritize frequent classroom observations, timely feedback, mentorship, and capacity-building initiatives for teachers to sustain and improve students’ academic outcomes.
