This systematic review explores the most validated methodologies for measuring managerial skills that contribute to sustainable organizational development, with a focus on confirmatory factor analysis (CFA). Using PRISMA guidelines and the PICOS framework, a systematic search in the Web of Science (6810 articles) and Scopus (11,267 articles) identified 27 relevant studies. Our findings emphasize the significance of valid, reliable measurement scales for key managerial competencies, such as leadership, decision-making, communication, and teamwork, which enhance employability and foster sustainable management aligned with the Sustainable Development Goals (SDGs). CFA emerges as a robust technique for ensuring methodological rigor in competency assessment, confirming theoretical models with empirical data. This study identifies gaps in current measurement frameworks, advocating for expanding models to incorporate digital transformation, sustainability leadership, and crisis management skills. Additionally, it underscores the importance of developing context-specific instruments that reflect sectoral and cultural variations. This review contributes to management education and workforce development by providing a validated framework for assessing managerial skills, supporting organizations in aligning leadership training with sustainability-driven business goals. Our findings offer practical implications for designing competency-based curricula and corporate training programs to enhance organizational resilience in an evolving global landscape.
