The Effectiveness of Teacher Performance in Terms of the Aspects of Principal Leadership, Organizational Culture, and Teacher Competence

This study will analyze principal leadership, organizational culture, and teacher competence on teacher performance. This study used a quantitative approach to causality. The data were collected through documentation and questionnaires. This study used a sample of 98 respondents to determine the sample size using the saturated sample formula. A partial least square was applied to examine the relationship of teacher performance, principal leadership, organizational culture, and teacher competence. The results of this study showed that of the three hypotheses formulated, two hypotheses were rejected, including the effect of the principal leadership variable on the teacher performance variable, in which the results did not have a significant effect, and the effect of the teacher competence variable on the teacher performance variable that obtained the same results, in which it did not have a significant effect. Meanwhile, the organizational culture variable had a significant effect on teacher performance. Through the findings of this study, it is expected to provide additional information for various parties, especially the Sultan Agung Education Foundation and the Education Authority of Pematangsiantar City in determining policies related to improving teacher performance.
