Asking why you want to be a doctor rather than a nurse is the most common follow-up to the why medicine question, and some medical schools ask it as a question in its own right. It is harder than it sounds. Most applicants either give an answer that could apply to any healthcare job, or say something slightly dismissive about nursing, and both lose marks. A good answer shows that you understand what nurses do, knows the real differences between the two roles, and explains why those differences point you towards medicine. This article goes through why schools ask it, what the marking criteria reward, how to structure your answer, and the other comparison questions you may be asked instead.
Why medical schools ask it
Motivation questions test whether you've genuinely thought through your decision. Comparison questions take that one step further by challenging you to justify your choice against the alternatives. If your reason for medicine was wanting to help people, nurses help people all day, so why not nursing? If it was a love of science, why not a science degree? The interviewer is checking that your reason survives that comparison.
They are also looking at how you talk about the rest of the healthcare team. Doctors work alongside nurses every day, and a candidate who is dismissive of nursing in an interview gives the interviewer a reason to worry. Accuracy matters for the same reason: inaccurate comparisons suggest you haven't done your research.
What the marking criteria reward
The marking sheet for this station has three content points, plus the usual mark for how clearly you communicate:
- Acknowledges value in nursing
- Highlights at least 2 reasonable differences between being a doctor and nursing
- Links how own desires and interests align with doctor’s role, affirms interest for being a doctor
For comparison questions, show respect and accuracy. Don't dismiss the alternative. Show you understand what that career involves, then explain why medicine specifically fits you better. The first point, acknowledging the value of nursing, is the one applicants most often leave out, and it is worth a full mark.
How to structure your answer
When asked why medicine rather than nursing, dentistry, or another path, strong answers follow four steps. This is the framework our interviewers mark against:
1. Introduction
Acknowledge that both careers are valuable and important to the healthcare team, but emphasise that being a doctor aligns better with your own values, strengths, and long-term goals.
2. Differences
Highlight reasonable differences between being a doctor and being a nurse, for example:
3. Personal fit
Link these differences to your own interests and motivations:
4. Conclusion
Conclude by:
Some differences you can draw on, depending on which career you are being compared with:
- Nursing :
- Different balance of clinical decision-making and responsibility; typically less involvement in diagnosis.
- Dentistry :
- More specialised focus on oral health; less involvement with systemic medicine.
- Pure science :
- More research and lab-focused; less direct patient contact.
Example answer
Here is an answer of about a minute that follows the four steps:
- Respect
- I have a lot of respect for nursing. On my placement the nurses were the people who knew the patients best, and most of the day-to-day care on the ward came from them, so for me this isn't a question of one job being better than the other.
- Differences
- The difference for me is where the decisions sit. The doctor's role carries the responsibility for diagnosis and the management plan, and it has a heavier academic and scientific emphasis, with more structured routes into research and teaching.
- Personal fit
- Those are the parts of medicine I'm drawn to. I enjoy working through a problem from first principles, and the thing I found most interesting on placement was watching the registrar weigh up two possible diagnoses and justify the plan to the team. I want to be the person making and owning that call.
- Conclusion
- So I want to be a doctor because the diagnostic and decision-making side of the job is where my interests and strengths are, while knowing that the care I'd be part of depends just as much on the nurses around me.

Common follow-up questions
The same question is asked against other careers, and some schools ask it in a broader form. Prepare the differences for whichever alternative is closest to your own background, since that is the one you are most likely to be asked about.
Why would you like to be a doctor rather than work in another health profession?
Asked at Aberdeen, Aston, Newcastle and Sheffield. The question is open, so choose one profession to compare medicine with rather than trying to cover several.
Why specifically do you want to be a doctor and not another healthcare professional?
Asked at Liverpool and Bristol. The answer is the same, but the word "specifically" is a cue to spend most of your time on the personal fit step.
Why do you prefer medicine over dentistry?
Asked at Bristol, Edge Hill and UCLan. Dentistry is more specialised and more hands-on, so the honest answer is usually about whether you want the breadth of medicine or the depth of one field.
You have studied sciences at A-level; why not study a science degree at university?
Asked at Glasgow. Pure science is more research and lab-focused, so the answer is usually about wanting to apply science to the patient in front of you.
Why did you choose to study medicine?
The question this one usually follows. The two answers need to tell the same story.
Common pitfalls
Things to avoid when answering the question:
- Being dismissive or disrespectful about nursing
- Not demonstrating any awareness of what nursing involves (suggests you have not considered the question seriously)
- Being too generic (e.g. "being a doctor is more interesting")
- Failing to link back to your own personal fit (why you specifically prefer medicine)
- Being overly rigid or disparaging (e.g. "I could never imagine being a nurse")
Which schools ask it
This question is usually asked as a follow-up inside a motivation station rather than as a station of its own. The schools below are the ones where applicants have reported it; each link opens the school's interview page.
- Exeter. Interviewers give a global judgement on whether you have shown the qualities to train as a doctor, so how you talk about nursing counts as much as what you say about medicine.
- King's. Asked alongside the why medicine question and "what have you done to make sure medicine is right for you".
Also reported at Imperial, Bristol, Buckingham, Plymouth and Southampton.
Frequently asked questions
What if I genuinely considered nursing?
Say so. An applicant who looked seriously at nursing and chose medicine for clear reasons gives a stronger answer than one who never considered it. Explain what drew you to nursing, then what made you choose medicine.
Is it a problem if a parent or relative is a nurse?
No, and it can help, because you will have a realistic picture of the job. Use what you have seen of nursing through them for the respect and differences steps, and keep the reasons for choosing medicine your own.
How many differences should I give?
Two is enough and is what the marking sheet asks for. Pick the two that honestly link to your own interests, rather than listing every difference you can think of.
