Bruce Macfarlane, the author of Intellectual Leadership in Higher Education, describes ‘professor’ as ‘a slippery term’. That’s because in the UK it means something quite different from what it denotes in North America. In North America ‘professor’ and ‘professorship’ are generic labels applied to all academics employed to research and teach in universities. In the UK, much of Europe (and, for the most part, in Australasia and South Africa), ‘professorship’ denotes distinction: a professor is someone who has been promoted to the highest academic grade – usually on the basis of her or his scholarly achievements. It’s the equivalent to what, in North America, is known as full professorship.

Some people are unclear about how someone known as ‘Dr’ is different from someone whose title is ‘Professor’. ‘Dr’ denotes someone who has studied for, and been awarded, a PhD, so it denotes an academic qualification: the holder of the highest university degree. It’s the equivalent of writing ‘PhD’ after someone’s name. Most professors will be PhD-holders, but so will be many – if not most – other academics employed as university teachers and researchers. ‘Professor’ doesn’t denote a qualification but an academic staff grade – the most senior one. So, in the UK, an academic whose title is ‘Dr’ is someone who’s got a PhD, but hasn’t been promoted to the highest academic grade, while an academic whose title is ‘Professor’ is someone who probably (but not necessarily) has a PhD, but who has been promoted to the highest grade on the university pay scale. Professorship therefore denotes seniority and status. If we make a comparison with medical doctors working in a hospital, all will have medical degrees, but they are employed at different levels of seniority, with consultants being the most senior doctors. We may think of professors as the equivalent of hospital consultants.
