At first glance these guidelines may appear to refer to the thesis, but they are really about the candidate. The first point makes this explicit: ‘The thesis demonstrates authority in the candidate’s field’. And consider the last point. The examiner has to consider whether the thesis ‘is a careful, rigorous and sustained piece of work’—but see how it goes on—‘demonstrating that a research “apprenticeship” is complete and the holder is admitted to the community of scholars in the discipline’.
[Y]our primary purpose in writing a thesis is to pass an examination. These examiners are not reading your work out of mere interest: from the above criteria, we see that examiners read your thesis to assess whether or not you have demonstrated your fitness to be admitted to a community of scholars. Because a written thesis is an examination paper, not simply a report of research findings, you need to understand what examiners are looking for when they read your work.
