There are factors that related with teachers performances, i.e organizational culture, transformational leadership of its principal, and work motivation, which was used as independent variable in this study. This research was aimed to study the strength and direction of correlation between independent variable and dependent variable (teachers performance), either individually or jointly. This research was conducted on 202 sample of teachers selected using multistage random sampling from 11 State Junior High School in Bogor, West Java. Combination method of quantitative and qualitative with sequential explanatory design was used in this study. The data was analysed using regression and partial correlation, simple correlation, and double correlation. The results showed that there is a significant and positive correlation between independent variable, consist of organizational culture, transformational leadership, and work motivation jointly, with teachers performance as dependent variable. The correlation coefficient is r_y.123 = 0.562 and coefficient of determination is r²_y.12 = 0.316. This means that all variables simultaneously have positive and significant correlation with teachers performance. These variable contribution are 31.6 %, while the other factors contribution are 68,4%.
