The purpose of this study was to investigate the relationship between the transformational leadership and job performance of second cycle high school teachers of Tehran. The present study was applied in terms of type and it was descriptive-correlational in terms of method. The statistical population included all Tehran second cycle high school teachers in 1397-98 academic year (N = 29756). The research sample consisted of 380 teachers who were selected through cluster random sampling method who were selected from second cycle high schools of Tehran. To collect the data, the standard questionnaire of Bass and Vulli (2000) and Paterson's (1999) job performance questionnaire were used. To ensure the validity of the questionnaires, their content validity and face validity were checked. In order to test the reliability of the questionnaires, the two questionnaires were distributed in a sample of 30 participants and their Cronbach's alpha was calculated using SPSS software. The alpha of the transformational leadership questionnaire was 0.93 and the job performance questionnaire was 0.85. The results showed that all aspects of the transformational leadership have a positive and significant relationship with the teachers' job performance, among which the correlation coefficient of the inspiring motivation (r = 0.491) was higher than the other components. The results of the step-by-step regression showed that from among the components of transformational leadership, in the first step, the component of the inspirational motivation by itself explains more than 23% of teachers' job performance and in the second step the component of the inspirational motivation along with the mental persuasion explain more than 26% of the teachers 'job performance. In the third step, the components of the inspirational motivation, ideal influence, and mental persuasion together predict more than 27% of the teachers' job performance. Beta coefficients showed that the variables of the inspirational motivation, mental persuasion and ideal influence predict the 0.38, 0.32 and 0.23 of the job performance variable, respectively. Therefore, it is possible to improve the teachers' job performance using the transformational leadership.
