Data analysis is carried out through prerequisite tests, namely normality, linearity, multicolonicity, and heteroscedasticity. After prerequisite testing, the analysis continues with regression tests. The results obtained stated that partially: 1) academic supervision affects teacher performance with a significant influence, namely 67%, 2) leadership effectiveness also contributes 51%. Simultaneous testing states that academic supervision and leadership effectiveness contribute significantly to teacher performance, which is 71% and the remaining 29% is influenced by other factors, therefore hypotheses regarding the influence of the two independent variables on the dependent variable can be stated.
