GTAC has been working in a partnership with the National Education Collaboration Trust (NECT) on the development of a series of case studies. The case studies are developed in order to inform learning and innovation in the education sector and in the public sector broadly. In 2014 the NECT identified the national examination system as a focus function from which lessons could be drawn about systems improvement. The choice of the examination system was based on the observation that the annual National Senior Certificate examinations, which come only second after the national general elections in size and scope, are being organised without major glitches. This case study presents a synopsis of the improvements in the management of the examination system that have been achieved since 1994 and highlights some key lessons.
