The research ethics committee (REC) is a key element of university administration and has gained increasing importance as a review mechanism for those institutions that wish to conduct responsible research, along with safeguarding research ethics standards, scientific merit and human rights of participants. Given the critical role of the university REC, it is argued that there is a need to assesses and understand the work of RECs to identify areas for improvement and thus focus on capacity building to respond to the escalating volume, type and complexity of research. This paper reports on the research ethics outcomes of a social science REC in a Business Faculty at a South African university during its seminal period of operation (2010-2015). Content methodology and a standardised questionnaire were used to assess the REC. The results show the increasing workload of the REC with favourable scores for submission/review processes and minute-taking. However, lower scores were seen for ethics education/training and tracking previously approved research. These shortcomings appear to be related to inadequate funding and resource support for research ethics education/training and administrative structures. Factors contributing to proposal rejections included weak research questions or hypotheses, poor questionnaires/interview schedule design and inadequate research ethics consideration in the proposal. It is argued that the complexity and escalation of research submissions to South African RECs necessitates that they are appropriately developed and capacitated to enhance their utility and thereby support the research mandate of universities.
