Abstract
The role of school leaders must be balanced in attaining educational sustainability in the changing world. Millions of school students worldwide were affected by the COVID-19 shutdown, which accelerated the need for rapid digitalisation. The United Nations Sustainable Development Goals (SDGs) are embedded in 21st-century education. The ability to reorient students to the SDGs is key to achieving sustainable education in the post-digital era. This study examines school leadership development in a post-digital era from the sustainability perspective. To ensure sustainable education, school leaders must have relevant skills and competencies to lead schools in the post-digital age. In striving for a sustainable era, a school leader needs skills and knowledge to be an inspiring role model and motivator. School leaders must reorient students, teachers, and all relevant stakeholders according to SDG goals to achieve sustainable education. Hence, continuous school leadership development is essential to accelerating digital transformation using factors such as leadership style, strategic planning, and knowledge management.
