Download on the App StoreWhat the Professional Discussion is
The Professional Discussion is the final assessment of the NEBDN Level 3 Diploma in Dental Nursing. It's a one-to-one conversation with an NEBDN assessor about how you work as a dental nurse: what you'd notice, what you'd do, who you'd tell and why. NEBDN describes it as based upon the nine duties of the dental nurse, in line with the Scope of Practice set out by the GDC, and on the knowledge and practical activities you've completed in the workplace.
It's one of three assessments on the Diploma, alongside the Portfolio of Evidence and the Knowledge Test. All three are graded pass or fail, and you need to pass all three to qualify and join the GDC register.
What makes it different is that there are no options to pick from. Every answer comes from you, out loud, and when an answer has a gap the assessor asks a follow-up question. Most candidates know the material. It's the nerves, the silences and the follow-ups that catch them out, which is why practising out loud matters so much.
The format: 10 minutes' reading, 60 minutes spoken
| Length | 60 minutes, plus 10 minutes' reading time |
| Who with | One NEBDN assessor |
| Where | Online |
| Based on | The nine duties of the dental nurse, and your own work in practice |
| Standard | The GDC Scope of Practice |
| Marking | Set and externally marked by NEBDN |
| Result | Pass or fail |
NEBDN doesn't publish the number of questions, the exact structure, the assessor's marking criteria or pass rates; those are restricted to approved training providers. We don't guess at them here. What's consistent is the shape: open questions across the duties, with probing follow-ups.
When you take it
The Professional Discussion comes last. You can only take it once you've passed your Portfolio of Evidence (built on PebblePad over at least six months) and the Knowledge Test (65 multiple-choice questions in 90 minutes). The qualification can't be awarded without it.
If you registered on the older National Diploma before 1 July 2025, you'll sit a written exam and an OSCE instead. This guide is for the Level 3 Diploma in Dental Nursing (RQF), which all new learners have registered on since 1 July 2025. Not sure which you're on? Our complete NEBDN Diploma guide explains both.
Read a short scenario, answer the assessor's question out loud, handle their follow-up probes, and get a marked mini report straight away. Then, when you're ready, sit full 60-minute practice discussions across all nine duties.
The nine duties, with example questions
The nine duties of the dental nurse come from the dental nurse apprenticeship standard (ST1431), and they map one to one onto NEBDN units 1 to 9. NEBDN's public specification refers to the nine duties without listing them, so treat this mapping as the best public guide rather than an official list. For each duty below you'll find what it covers, a realistic example question, and what a strong answer shows.
Duty 1: Assessment and diagnosis
Your role before and during an examination: medical histories, charting as the dentist dictates, radiographs only if you're trained and entitled, and spotting anything that changes how the patient should be treated.
"Looking at this patient's new patient appointment, talk me through your role before and during the examination."
- Medical history checked, signed and seen by the dentist
- Risks flagged before treatment starts (medication, missed meals, allergies)
- Charting recorded as dictated, never independently
- Radiographs only if trained and entitled as an operator
Duty 2: Treatment planning and onward referral
Supporting the dentist's treatment plan and referrals, including urgent ones, without making clinical decisions that belong to the dentist.
"The dentist notes a red and white patch on a patient's tongue. What is the dental nurse's role from this point?"
- Recognises a possible warning sign
- Knows the dentist makes the referral, and how urgently
- Gives an honest, within-scope answer if the patient asks 'is it cancer?'
- Logs the referral and checks the appointment arrived
Duty 3: Communication, confidentiality and records
Talking with patients and colleagues, valid consent, interpreters, information governance, and accurate, contemporaneous records.
"A patient's 15-year-old daughter has come to interpret for her extraction. What are your thoughts about this?"
- Why a child shouldn't interpret for consent: accuracy, confidentiality, the burden on the child
- Arranging a professional interpreter, rebooking if needed
- Not confirming anything about a patient to an unverified caller
- UK GDPR, the Data Protection Act 2018 and GDC principle 4
Duty 4: Professional leadership within the team
Leadership as behaviour, not job title: taking ownership, supporting colleagues and improving how the team works.
"As a trainee, how do you show leadership within your team? Give me an example from your own practice."
- A specific example from your own work, with an outcome
- Leadership shown through behaviour, not seniority
- Only taking on tasks you're trained, competent and indemnified for
Duty 5: Professional practice: scope, law, ethics and safeguarding
Working within the GDC Scope of Practice and Standards for the Dental Team, raising concerns, and safeguarding children and adults at risk.
"Your colleague says she re-uses single-use matrix bands because the principal says stock is tight. What would you do?"
- Single-use items are never reprocessed, whoever says so
- Raising the concern, then escalating (manager, then the GDC or CQC if needed)
- Telling the safeguarding lead the same day about a possible safeguarding concern
- Consent from someone with parental responsibility
Duty 6: Inclusive, non-discriminatory practice
Equality, diversity and reasonable adjustments, so every patient can access care, and challenging discrimination when you see it.
"How do you make sure every patient at your practice is treated fairly and can access care? Use examples where you can."
- The Equality Act 2010 and its protected characteristics
- Practical, real reasonable adjustments
- Recognising unconscious bias
- Challenging and reporting a discriminatory comment
Duty 7: Promoting oral health
Tailored, evidence-based oral health advice and signposting, in line with Delivering Better Oral Health.
"What oral health advice and support would be appropriate for this patient?"
- Advice tailored to the patient's age, risks and history
- Fluoride toothpaste strength and 'spit, don't rinse'
- Very brief smoking advice and referral to stop smoking services
- Links between general and oral health, such as diabetes and gum disease
Duty 8: Reflection and the quality of your own practice
Learning from your own mistakes and feedback, quality improvement and your continuing professional development.
"Tell me about a time something did not go as planned in your work. What happened, and what did you learn?"
- An honest example of your own error or difficulty
- Ownership, the impact, and what was reported
- What you changed, and how you checked it worked
- Your CPD: enhanced CPD and a personal development plan
Duty 9: Your own health and well-being, and the team's
Looking after yourself and colleagues: debriefs, occupational health, sharps injuries, immunisation and not practising when unfit to.
"After the emergency with this patient, how would you look after yourself and the team?"
- A structured team debrief and peer support
- Hepatitis B immunity, PPE, sharps procedures and posture
- Not working when unwell in a way that puts patients at risk
- Supporting a colleague who is struggling
Medical emergencies
Medical emergencies (Unit 10)
Unit 10, Respond to Risks and Medical Emergencies, sits within Duty 1 in the apprenticeship standard, and medical emergency scenarios are a natural fit for the discussion: recognising what's happening, calling for help, the right drug or action within your role, and what happens afterwards.
"A diabetic patient who skipped breakfast is sweating, confused and slurring his words in the waiting room. Talk me through what you would do."
- Recognises probable hypoglycaemia, keeping stroke in mind
- Calls for help, alerts the dentist, brings the emergency kit and oxygen
- Oral glucose only if conscious and able to swallow; nothing by mouth if not
- 999, and CPR 30:2 with an AED if not breathing normally
- Records, debriefs and restocks afterwards
Medical emergency answers are where order matters most. Say what you think is happening and why, call for help, and give only what's within your role and your practice's protocol. Then say what happens afterwards: the record, the team debrief and restocking the kit.
How to answer well
Use a simple structure
For scenario questions, work through four steps out loud: what you'd notice, what you'd do within your role, who you'd tell, and what you'd record. It keeps you in scope, stops you rambling, and shows the assessor your thinking.
Stay inside your scope of practice
You're answering as a dental nurse, not a dentist. Diagnosing, prescribing or deciding treatment in an answer can cost you the duty. Say what you'd notice and flag, and that the decision is the dentist's.
Bring your own examples
The discussion is based on your work in practice, so the strongest answers use real, anonymised examples. Prepare one for each duty before the day: something that went well, something that went wrong, a time you raised a concern, and a patient you helped communicate with.
Reflect with "what, so what, now what"
For reflection questions: what happened, why it mattered, and what you changed afterwards (and how you checked the change worked). Owning a mistake honestly scores better than a story where nothing went wrong.
Treat follow-ups as a second chance
A probing question usually means your answer left something out. It's not a sign you're wrong: add the detail the question is pointing at, rather than repeating yourself.
The mistakes that cost candidates
A four-week preparation plan
Resits, fees and sitting windows
You can resit the Professional Discussion up to three more times. After the maximum number of attempts you'd need to start the course again, and you can't resit to improve a grade.
| Resit fee | £300, charged by NEBDN to your training provider (some providers add their own admin fee) |
| Late deferral | £300 if within four weeks of your Professional Discussion |
| Appeal | £50, refunded if your appeal is upheld |
| Sitting windows | Multi-day windows, usually January and June. Published: 5 to 21 June 2026; 8 to 24 January 2027 (results 25 February 2027); 4 to 20 June 2027 (results 22 July 2027) |
A failed attempt can mean waiting up to five months for the next window, which delays joining the GDC register and earning as a qualified dental nurse. Always check NEBDN and your provider for the current dates and fees.

NEBDN Professional Discussion questions, answered
It's the final assessment for the NEBDN Level 3 Diploma in Dental Nursing. It lasts 60 minutes, with 10 minutes' reading time, and is carried out online with an NEBDN assessor. It's based on the nine duties of the dental nurse and on the knowledge and practical activities you've completed in the workplace, in line with the GDC Scope of Practice. It's set and externally marked by NEBDN and graded pass or fail.
Last. You can only take it once you've passed both your Portfolio of Evidence and the Knowledge Test, and the Diploma can't be awarded without it.
60 minutes, with 10 minutes' reading time beforehand.
NEBDN doesn't publish its questions or the assessor's criteria. The discussion is based on the nine duties of the dental nurse, so expect open questions such as 'talk me through what you would do', followed by probing questions when an answer leaves a gap. This guide lists a realistic example question for each duty.
NEBDN grades it pass or fail and doesn't publish a pass mark or pass rates. Prepare to show safe, within-scope practice across every duty, because an unsafe answer can cost you on its own.
You can resit it up to three more times. The NEBDN resit fee is £300, charged to your training provider (some providers add their own fee). After the maximum number of attempts you'd need to start the course again. You can't resit to improve a grade.
NEBDN runs multi-day windows twice a year. Published windows include 5 to 21 June 2026, 8 to 24 January 2027 (results 25 February 2027) and 4 to 20 June 2027 (results 22 July 2027). Check NEBDN for the latest dates and deferral deadlines.
NEBDN's public documents don't say what you may have on your desk or whether notes from the reading time can be kept. Ask your training provider, and practise answering without notes so it doesn't matter.
Learn the nine duties, prepare one real, anonymised example from your own practice for each, and practise answering out loud, ideally in full timed mock discussions with probing follow-up questions. Focus extra time on medical emergencies, safeguarding and reflection, where answers are most often vague.
Yes. PrepSuite's Professional Discussion practice lets you answer one real question out loud for free, with a live interactive assessor who probes your answer, and gives you a marked mini report straight afterwards. Full 60-minute practice discussions across all nine duties can then be unlocked.
No. Learners who registered on the National Diploma before 1 July 2025 sit a written exam and an OSCE. Learners on the Level 3 Diploma in Dental Nursing (registrations from 1 July 2025) take the Portfolio of Evidence, the Knowledge Test and the Professional Discussion instead.
