This study aims to conduct a systematic synthesis of available empirical evidence to empirically ascertain the impact of Board of Directors' competence on earnings management practices in Islamic banking. The research employs a qualitative literature review approach. A literature search was performed on the Scopus database for the period 2010–2025, utilizing a combination of the keywords "Islamic bank," "Board of Director," and "Earnings Management." From an initial pool of 127 identified documents, a rigorous screening process based on inclusion and exclusion criteria yielded 53 reputable journal articles as the final units of analysis. Data analysis was conducted using thematic analysis to synthesize substantive findings. The synthesis results consistently confirm that Board of Directors' competence demonstrates a negative and significant impact on earnings management practices in Islamic banking. However, the effectiveness of this impact is not homogeneous. The principal findings identify three crucial boundary conditions: (1) The presence of specific expertise in finance and Sharia contracts at the board level serves as the primary differentiator of supervisory effectiveness; (2) The complementary interaction with the Sharia Supervisory Board (SSB) moderates the strength of this relationship; and (3) The regional institutional context (centralization model in Southeast Asia vs. decentralization in the GCC) significantly influences the effectiveness of governance in curbing the manipulation of discretionary accounts, including the Profit Equalization Reserve (PER).
