This study aimed to develop professional educational leadership for sustainable education within the Sustainable Development Goals (SDG) framework. The objectives were: (1) to examine leadership competencies that promote sustainable education and support the SDGs; (2) to develop strategies and methods for fostering long-term sustainable leadership practices; and (3) to implement and evaluate the developed leadership development program. A qualitative design was used with in-depth interviews, focus group discussions, document analysis, and observations of educational leaders from various institutions in Thailand. Findings revealed six essential competencies: strategic vision, emotional intelligence, ethical decision-making, collaborative management, sustainability literacy, and reflective adaptability. Strategies and methods included mentorship, collaborative learning communities, reflective practice, and sustainability-focused workshops. The program implementation improved leadership performance, institutional sustainability, and alignment with SDG 4 (Quality Education) and SDG 17 (Partnerships for the Goals). The study concludes that competency-based, participatory, and sustainability-driven leadership development is key to advancing professional educational leadership and achieving sustainable education goals..
