This article seeks to spark a dialectic discussion on the establishment of a set of professional competencies for quality assurance practitioners who serve in external quality assurance agencies in higher education. Such a need is identified due to the shortage of relevant and sufficient coverage in the quality assurance literature. To substantiate the need, the concepts of professionalism and profession, and how these concepts are linked to the quality assurance in higher education sector, are carefully examined through a desk-top research study. References are drawn from the experiences in several other occupations. The result reveals that the development of the essential competencies for external quality assurance practitioners in higher education is valuable and essential and it will be useful for the practitioners to transform themselves into a profession in the long run.
