Master's vs PhD defense
What committees expect at a master's defense compared with a doctoral defense, and how to prepare for the one you actually have.
The standard is not a smaller version of the same talk
A master's defense asks whether you can design, carry out, and explain a bounded study, and whether you understand what it does not show. A PhD defense asks whether the work is a contribution: new relative to a literature you genuinely know, defensible in its method, and honest about what it changes and what it leaves open.
Candidates get into trouble when they borrow the other standard. A master's student who claims a field-defining result will be asked to walk it back. A doctoral candidate who describes the work as a class project will be asked where the contribution is.
What changes in the questions
Master's committees spend more time on whether you understand your own method and your own data. They will ask you to explain a choice simply, and they will notice if the explanation is memorized. Depth of adjacent literature matters less than accuracy about what you did.
Doctoral committees spend more time on originality, on the literatures you are in conversation with, and on alternative explanations that a specialist would raise. They may ask what you believe now that you would not have believed when you proposed the project. That answer cannot be a recitation of the proposal.
Prepare to the degree you are sitting
Set the degree level when you run an audit. The questions should change with it. For a master's draft, a fair committee presses scope and execution. For a doctoral draft, the same pages get pressed on contribution and on the claim you are willing to sign.
Either way, the oral exam is you speaking, not a model speaking for you. Use a mock defense to find the sentence you cannot yet say. Then practice that sentence until it is yours.
MockCommittee will not draft, rewrite, or polish thesis or dissertation prose for you to submit. A stronger answer is a spoken reply you can study aloud. Putting it into the document is academic misconduct.
