This study addresses the growing concern of academic misconduct in academic writing by systematically identifying and evaluating strategies to mitigate unethical practices across multiple levels. By reviewing 61 relevant studies, this study initially extracted 252 strategies, which were then refined to eliminate redundancies and categorized using 4M framework. The framework segments the strategies into micro-, meso-, macro-, and mega-levels. At the micro-level, individual-focused interventions such as targeted workshops, mentorship programs, technology literacy, and early ethics education are emphasized. Meso-level strategies involve departmental actions including faculty training, curriculum integration, policy development, and assessment alignment to reinforce ethical writing practices. Macro-level strategies underscore the importance of robust institutional frameworks, comprehensive awareness campaigns, and support services that foster a campus-wide culture of integrity. Finally, mega-level strategies extend these efforts beyond individual institutions by promoting inter-institutional collaborations and engaging external stakeholders to establish unified standards and practices. The findings highlight that a holistic, multi-levelled approach is essential for effectively deterring academic misconduct and cultivating a sustainable culture of academic integrity in higher education.
