The multiple regression relationship is linear with the equation model Y = -44.596 + 1.021 X1 + 0.606 X2; 2) The independent variables of school principal supervision (X1) and motivation (X2), both individually and together, make a significant contribution to the dependent variable of teacher performance (Y). The contribution of each independent variable to the dependent variable is as follows: school principal supervision variable is 67.8% and motivation variable is 48.8%. The contribution of both independent variables together to the dependent variable is 76.4%. Knowing that the contribution of school principal supervision (X1) and motivation (X2), 76.4%, to the performance of the teacher (Y), it can be concluded that 23.6% of the performance of the teacher is due to other factors]]>
