Qualified

Three qualified people is what you have, at a minimum, at your viva.

Every viva in the UK has one candidate and at least two examiners.

The latter are qualified because of how they are selected. They need to meet criteria, such as having a doctorate, experience and training. There will be a specific reason why they were asked to be your examiners rather than someone else.

You are qualified because you did the work. You invested the hours. You made something. So you’re capable now and qualified to be at your viva.

Remember: qualified is not a synonym for perfect. No-one at your viva is perfect or is expected to be perfect. You’re all just continuing to demonstrate your best and most capable selves.
