This paper provides an overview of the various data sets pertaining to education in South Africa that are informing or could inform policy making in education. The paper serves as an inventory for anyone interested in understanding what data is available, how it may be accessed, what the quality of the data is, and in what formats it may be accessed. The paper is divided into three parts. The first part provides a description of existing education data sets and the basic data elements contained in each of these data sets. When discussing each of the existing education data sets, the paper addresses the quality of the education data available in South Africa. The first part also refers to the policy implications and the important role that data plays in policy formulation. No information system on its own is comprehensive enough to provide all the information needed in strategic decision-making. Hence, part two of this paper discusses the need for data integration as an important data management strategy. The third part examines the effectiveness of implementing a learner unit record system nationally in comparison with the EMIS system that is currently in place and that is based on aggregate or summary institution-level data.
