This is evident from the results of the first hypothesis test with product moment correlation analysis which obtains the price rx1y> rtable (50; 0.01)> rtable (50; 0.05) = 0.472> 0.361> 0.279. (b) There is a positive relationship between Teacher's Interpersonal Communication with Teacher Performance in Tolai Torue DDI Elementary School. This is evident from the results of the second hypothesis test with product moment correlation analysis that obtained rx1y> rtable (50; 0.01)> rtable (50; 0.05) = 0.418> 0.361> 0.279, (c) There is a positive relationship between Leadership Styles Principal and Interpersonal Communication Teachers with Teacher Performance at SD DDI Tolai Torue. This is evident from the results of hypothesis testing with regression analysis of two predictors that obtain Freg> Ftable (2; 47; 0.01)> Ftable (2; 47; 0.05) = 0.913> 5.08> 3.21. (D ) The Principal Leadership Style Variable contributes 59.2% relative and 17.6% effective contribution.
