Abstract:The aims of this study are; (1) to review the sustainable development and sustainability practices for the Higher Education Institute (HEI) and (2) to present a conceptual framework of the dimensions of sustainability practices for the National Defence University of Malaysia (NDUM). This study uses a comprehensive literature review on sustainable development and sustainability practices in the HEI from year 1997 to 2016 at the national and international levels. This study identifies nine dimensions of the conceptual framework of sustainability practices for the NDUM which include: (1) Corporate Governance, (2) Students, (3) Staff, (4) Societal, (5) Environment, (6) Companies, (7) Health and Well-being, (8) Economic and Wealth, and (9) Continuous Improvement. This study can be extended to the construction of a survey to identify the items involved in each dimension of sustainability practices of the HEI in detail. In addition, this study can be lengthened to the creation of a sustainability index for the HEI to be used as a key performance index. Finally, this study can also be used for empirical studies to investigate the relationship between dimensions, regression and comparative study on sustainability practices among the HEI.
