The PhD viva is an oral assessment held by a committee during the PhD defense. This evaluation involves the committee posing inquiries to the PhD candidate regarding their research work and dissertation.
The candidate must showcase their expertise in the field and how it relates to their project’s focus. The primary aim of the PhD viva is to ascertain if the candidate has fulfilled the criteria for obtaining their degree.
This article explores the PhD viva questions, provides 18 sample questions, and offers advice on responding to them effectively.
PhD viva
A PhD viva, also known as a viva voce, is the concluding assessment where a candidate addresses inquiries posed by an academic committee regarding their completed work and understanding of their chosen field.
It serves to evaluate whether the candidate has effectively shown their comprehension of their specific research domain to produce original contributions.
The questions asked during a PhD viva typically come from the candidate’s original work proposal and other submitted written materials.
Types of PhD Viva Questions
Examiners typically prepare a set of questions for candidates to address during the PhD viva voce exam. These questions primarily center around the candidate’s thesis.
However, the questions asked in PhD viva exams can generally be categorized into four main areas:
- General Questions
- Research Context and Methods
- Analysis and Findings
- Discussions and Conclusion/Implications
Therefore, as you prepare for your PhD viva and defend your thesis, it’s crucial to consider the types of questions you might encounter.
This preparation allows you to practice your responses beforehand, ensuring you are not caught off guard during the viva.
Preparing and practicing your responses to questions from these four fundamental categories will significantly help in your preparation efforts.
Frequently Asked Questions for PhD Vivas and How to Answer to Them
While focusing on addressing frequently asked questions may seem straightforward, it’s crucial to prepare for potential follow-up questions. Nervousness can sometimes cause digressions, leading to unexpected inquiries from examiners in areas that may not have been anticipated.
