22 February 2021 - Wits University The NRF has re-awarded A-ratings to four Wits scientists, a grading which confirms that they are recognised as leading international scholars in their fields. The A-ratings of Professor Christopher Henshilwood, Professor Bruce Rubidge, Professor Bob Scholes, and Professor Roger Smith apply from 1 January 2021 to 31 December 2026. According to the National Research Foundation (NRF), an A-rating indicates “researchers who are unequivocally recognised by their peers as leading international scholars in their field for the high quality and impact of their recent research outputs.” Furthermore, Henshilwood and Smith, who previously held A2 ratings, are now A1-rated. A researcher in the A1 group is “recognised by all reviewers as a leading scholar in his/her field internationally for the high quality and wide impact, i.e., beyond a narrow field of specialisation, of his/her recent research outputs”, according to the NRF.
