This research aims to examine the influence of academic supervision, school culture and leadership on teacher performance at MIN 1 Gresik and SDI Al Muttaqin Driyorejo Gresik. Teacher performance is a key factor in achieving quality education goals, and is influenced by various external elements. The research method used was a quantitative approach by collecting data through questionnaires from 55 respondents. The results of the research show that academic supervision has a significant effect on teacher performance (t = 2.999; p = 0.004), school culture has a significant effect on teacher performance (t = 5.714; p = 0.000), principal leadership plays an important role in improving teacher performance (t = 5.773; p = 0.000). An R Square value of 0.900 means that 90% of the variation in Teacher Performance can be explained by these three variables, while the remaining 10% is influenced by other factors. This shows that effective academic supervision, positive school culture, and good leadership contribute significantly to improving teacher performance. This research also provides recommendations for schools to strengthen academic supervision and create an inclusive and collaborative school culture. Thus, it is hoped that the research results can become a reference in improving the quality of education at the two institutions.
