Worldwide, in Africa and in South Africa, the importance of the doctorate has increased disproportionately in relation to its share of the overall graduate output over the last decade. This heightened attention has not only been concerned with the traditional role of the PhD, namely the provision of a future supply of academics. Rather, it has focused on the increasingly important role that higher education – particularly high-level skills – is perceived to play in national development and the knowledge economy. This book is unique in the area of research into doctoral studies because it draws on a large number of studies conducted by the Centre of Higher Education Trust (CHET) and the Centre for Research on Evaluation, Science and Technology (CREST) over the past decade.
