The viva is the one moment where you are asked to tell the story of your year. Many apprentices prepare it like a school exam, when it assesses something else: your ability to step back from a professional experience. Here is the method we recommend on SuperAlternant.
What the panel is really assessing
The panel already knows your dissertation — they have read it. They are not expecting a summary but a demonstration that you understand what you did: why that research question, what decisions you took, what you would do differently.
The most common mistake is to walk through the dissertation chapter by chapter. It is the surest way to lose a panel within four minutes.
A structure that works
For a twenty-minute talk, this split stands up in almost every case:
- 2 minutes: the company context and your assignment, one sentence each;
- 3 minutes: the research question and why it genuinely arose;
- 10 minutes: your approach, your choices, your measured results;
- 3 minutes: the limits of your work and what you take from it;
- 2 minutes: where it leads professionally.

The confidentiality question
Many apprentices discover this too late. If your dissertation contains sensitive data, ask your company several weeks in advance what may be presented and what must be anonymised.
A confidentiality clause is requested from the school beforehand: the dissertation is then readable by the panel alone. Anonymising figures at the last minute produces an unreadable talk.
The recurring questions
Prepare three of them explicitly: "What did not work?", "If you started again, what would you change?" and "How did your work serve the company?"
Answering "everything went well" is the worst option. A panel is looking for clear-sightedness: naming a failure and what you drew from it beats any polished presentation.
