This is rather concerning (but not particularly surprising, as we’ve heard all those complaints about GCSE, A-Level, degree level standards dropping, etc.) re PhD doctorates. Really, by the time you sit the viva, you should know that your work is ready to pass, and that your job in the viva is to demonstrate that you actually wrote it (although others will still see it as a test) … and as I hope to take on a PhD student before too long:
Our experience does not lead us to criticise any particular system of examination or type of thesis. However, it does raise serious issues about the quality of work submitted for the PhD degree (or its equivalent) and the standards employed to judge such work.
To cut to the chase, a significant number of the theses we have examined did not deserve to pass – at least, not in the form in which they were submitted. One of us has examined six doctoral theses in the past year and believes that not one of them was worthy of the degree. Yet he had the means at his disposal to fail only two of them. Administrative conventions and examination procedures, not to mention social pressures, simply did not allow the possibility of failure.
