You need to have made a significant, original contribution with your research. Defining the standard for that is hard, but we can rule some things out. The standard is not…
- …producing two papers during your PhD.
- …having at least six chapters in your thesis.
- …70,000 words.
- …a minimum of 200 references in your bibliography.
- …working yourself into a shell of your former self.
The standard is good enough.
Are your research and your thesis good enough? Are you good enough?
Good enough might still be tricky to define. Together you and your supervisors can establish some helpful criteria that can show you’re meeting the standard. It has to be discussed because every thesis is different, but figuring out what good enough means for your work, and knowing you’ve met the standard is a huge confidence boost for the viva.
