The present paper attempts to analyse the effect of organizational climate on organizational citizenship behaviour (OCB), as well as the effect of OCB on turnover intention. Data on organizational climate, OCB and turnover intention were obtained from a sample of 78 internal auditors of Jordanian private universities. Hypotheses were proposed and were tested using PLS-SEM, and the outcomes demonstrate the positive linkage between organizational climate and OCB. Meanwhile, OCB and turnover intention were found to have inverse linkage. Strong organizational climate should be created in Jordanian private universities since it improves and predicts OCB. OCB will in turn cause turnover intention to decrease among internal auditors. With the use of PLS-SEM method, this study adds to the extant literature.
