Why South Africa's PhD candidates have almost doubled in the past decade
South African officials appear to be taking steps to ensure that the quality of doctoral education and degrees in the country meet international standards.
The number of doctoral candidates has more than doubled in the past 10 years.
Professor Sioux McKenna, an expert on postgraduate studies, says the rapid growth in doctoral candidates can be attributed to the changing nature of the PhD.
The professor explains that a doctorate is no longer a purely academic feat, but it's evolved into a useful tool to drive attention towards industrial, commercial, social and environmental issues.
In 2010 we had close to 1,500 doctoral candidates and now we are sitting at around 3,000.Professor Sioux McKenna, Director - Centre for Postgraduate Studies at Rhodes University
