The aim of this study was to investigate the relationship between principals' leadership styles with Performance of physical education teachers in secondary schools in western provinces of Iran. This study was a descriptive-correlation, and the statistical community included all physical education teachers and students of secondary level schools in the West region of Iran (Ilam, Kermanshah, Kurdistan, Lorestan) in 2012-2013. Using cluster sampling, 300 students and 300 teachers were selected as sample. Data were gathered using Likert style questionnaire and Babaee et al efficiency questionnaire (2003). Reliability coefficient of the questionnaires was calculated using Cronbach's Alpha for the two mentioned questionnaires and the results were respectively 0/83 and 0/81. For data analysis, inferential test of Kolmogorov - Smirnov was used, and to determine the normal distribution of the data, Pearson correlation and multiple regression analysis were used. The results showed that the correlation coefficient between the leadership style of principals and performance of teachers was equivalent to 0/16. In other words 26% (r2=26%) of the efficiency variance is explained by Likert leadership style dimensions. In addition, the findings from the multiple regressions showed that the dimensions of leadership style together could not express a significant influence on teachers' performance. However, investigation of each dimension alone showed that among Likert management styles, only partnership and consultative styles could have a significant influence on teachers' performance
