ABSTRACT: The purpose of this study is to examine the reliability and construct validity of organizational citizenship behaviour, to find dimensions and indicators that can form organizational citizenship behaviour. Organizational citizenship behaviour measured by the dimensions of altruism, courtesy, conscientiousness, sportsmanship, and civic virtue. The population in this study were teachers in junior high schools in Purwokerto region with a total of 327 teachers. The sample of this study was 90 teachers. The sampling technique in this study uses accidental sampling. Data collection methods use the organizational citizenship behaviour scale. Research data were analyzed with Structural Equation Modeling (SEM) through the SmartPLS 3.2.8 program. Based on the analysis results, the dimensions and indicators that form the construct of organizational citizenship behaviour are declared valid and reliable. The most dimension that reflects the construction of organizational citizenship behaviour is a civic virtue, with a loading factor of 0.781. The lowest dimension that reflects the construct of organizational citizenship behaviour is courtesy with a loading factor of 0.400. This research shows that all dimensions and indicators are able to reflect and form the construct of organizational citizenship behaviour. Thus, the measurement model can be accepted because the theory was described organizational citizenship behaviour is consistent with empirical data obtained from the subject.
