This paper argues that for the government to be able to provide evidence of performance of its policies, it must institutionalise an outcomes-based evaluation system. An Outcomes-based Policy Evaluation system is presented in this paper as a tool through which the government can objectively demonstrate achievements of its policies while at the same time accounting about the performance of its policies. However, for such a framework to be successful it must be embedded on a well crafted evidence based system. Thus, the researcher will argue that Evidence-based practice is a cornerstone for an outcomes-based policy performance system. Hence a saying that the system will only be as good as the data that it is based on holds true for this paper.In support of this exposition, Rosanbalm, Owen, Rosch and Harrison (2009:6) contend that evidence-based policy provides an effective mechanism to establish, in a scientifically valid way, what works or does not work, and for whom it works or does not work. With this structured approach to evaluation, knowledge can be used to improve practice, allowing successful programs to develop iteratively over time. Without this approach, interventions go in and out of practice, little is learned about what works, and the effectiveness of social programs does not advance significantly over time. Rigorous evaluation can end the spinning of wheels and bring rapid progress to social policy as it has to the field of medicine.
