The aim of this research in correlational survey model is testing the mediating effect of organizational identification on the relationship between leader-member exchange and organizational commitment by the use of structural equation model. The study group of the research consists of 391 teachers working at 21 different primary schools in Çankaya province of Ankara and selected by simple random sampling method. Data of the study was obtained by using Leader-Member Exchange Scale (LMXS), Organizational Identification Scale (OIS) and Organizational Commitment Scale (OCS). In the research descriptive analyses (mean, standard deviation, ratio and frequency), Pearson product-moment correlation, single factorial CFA, first-order CFA were carried out and for mediating analysis structural equation modal (SEM) was used. The results revealed that the level of leader-member exchange is "Very high", organizational commitment is "Medium" and Organizational identification is "High". According to Pearson product-moment correlation analysis, significant positive relationships were found between variables. The results of path analysis also showed that in the relationship between leader-member exchange and organizational commitment, organizational identification has "partial mediating" effect. A number of suggestions have been offered to practitioners and researchers in line with the results obtained from the research.
