Therefore, this study aims to analyze the effect of the practice of shariah governance to the quality of GCG implemented by Islamic banks. Practices of shariah governance are measured by number of shariah board members, doctoral qualification of shariah board and frequency of shariah board meeting. The study finds that shariah governance has a significant impact to the increase quality of GCG in Islamic banks.
