The main aim of this study was to explore and describe the circumstances on the ground concerning employability of Environmental Science (ES) graduates in Botswana and to provide evidence that would either confirm or refute claims that graduates in Botswana, in general, are not employable. The second aim of this study was to describe whose role it is to enhance the employability of graduates. Furthermore it was also the aim of this study to investigate whether or not employability audits could be used as a quality assurance mechanism to ensure the employability of graduates in Botswana. These issues were investigated using the contextual framework of employability which explains the quality of higher education in relation to employability of graduates. This research reports on the findings of a case study of the Environmental Science programme offered by the Department of Environmental Science at the University of Botswana which was conducted in June 2012. The study revealed and confirmed gaps among ES graduates in the knowledge, skills and competencies required for the world of work. As a result of these gaps, ES graduates were found not be immediately employable without further on the job training. This created a lot of discontent among employers interviewed. The study concluded that higher education should go beyond providing education for the general development and well-being of individuals and address issues related to employability of graduating students. Conflicts in the possible roles of higher education and industry in enhancing the employability of ES graduates in terms of the changing expectations of the world of work were identified. The study highlighted the possible role of employability audits in enhancing employability not only of ES graduates but all other graduates in Botswana. Furthermore the study recommended that employability audits should be introduced in the tertiary education system of Botswana as a quality assurance mechanism. It further recommended collaboration and partnership with industry as key to the success of any measures put in place for the enhancement of the employability of graduates in Botswana.
