Abstract This study aims to reveal the mediating role of learning organization (LO) in the effect of principals' instructional leadership (IL) competencies on teacher motivation (TM). The correlational survey design was used to determine the relationship between variables. The study group of the research consists of 403 teachers who are employed in the Pendik, Tuzla, Adalar, and Maltepe districts of Istanbul, Ministry of National Education. The Personal Information Form, Instructional Leadership Scale, Teacher Motivation Scale, and Learning Organization Scale were used to collect data. It was checked whether the data obtained during the data collection process showed normal distribution, and the results of the Pearson correlation analysis between the variables were evaluated. In order to test the theoretical model developed by the researchers, Structural Equation Modeling (SEM) analyses were conducted. Considering the purpose of the study and the analyses, it was observed that there was a significant positive relationship between principals' instructional leadership competencies and teacher motivation and learning organization, and a significant positive relationship between learning organization and teacher motivation. The SEM model developed based on the results that IL has an effect on LO and TM, and that LO has an effect on TM, was tested. As a result of this test, it was determined that LO had a full mediating role in the effect of IL on TM. In conclusion, the theoretical model developed by the researchers was tested and accepted based on the fit values.
