The study aimed to present a proposed strategy for managing the diversity of academic human resources in higher education institutions in the Sultanate of Oman in light of the standards of Omani Authority for Academic Accreditation and Education Quality Assurance. The strengths and weaknesses in the internal environment in high education institutions have been identified, the available opportunities and potential threats in the external environment that affect the achievement of diversity management in those institutions were also identified. Consequentially, results of the quaternary analysis of the environment affecting the achievement of diversity management in high education institutions in the Sultanate of Oman were reached. The study employed the Mixed Method approach based upon the sequential exploratory design, by which qualitative data were collected and analyzed through controlled interviews that the researcher asked to (19) university leaders. They answered (15) total questions, followed by a quantitative analytical study represented in the (SWOT) questionnaire. It was applied to (140) heads of scientific departments, as experts in selecting and appointing academic staff members in six universities in the Sultanate of Oman as the study sample. The study reached a set of important results related to managing the diversity of academic human resources in higher education institutions. The most notable one is the weakness of applying diversity management of academic human resources in higher education institutions in the Sultanate of Oman, despite of the diversity of those resources. These institutions are distinguished by the large number of academic staff members’ nationalities as a dimension of diversity and their different academic qualifications, as well as the infrastructure of these institutions that is appropriate and incentivized to attract faculty members. All of that requires the availability of the organizational umbrella for these institutions, which is the establishment of a unit concerned with diversity management providing mechanisms of structures, legislations, plans, and programs that enable an effective implementation of the diversity management. The study concluded with a proposed strategy for managing the diversity of academic human resources in higher education institutions in the Sultanate of Oman in light of the standards of the Omani Authority for Academic Accreditation and Education Quality Assurance.
