One of three assessments in the NEBDN Level 3 Diploma, alongside your Portfolio of Evidence and a Professional Discussion with an examiner.
NEBDN does not publish a pass mark for the Knowledge Test, so we don't quote one. Our practice threshold of 70% is a preparation target, not an official figure.
Every topic on the syllabus
Both free mocks draw from all ten, in the same proportions as the real paper — so a weak topic shows up as a weak topic, not as a gap in the practice set.

NEBDN questions, answered
It is the qualification most UK dental nurses take to register with the General Dental Council. It is awarded by the National Examining Board for Dental Nurses and covers 10 units including Clinical Practice, Communication, Responding to Medical Emergencies, Teamwork and Professional Development. It is aligned to the GDC's Safe Practitioner Framework for Dental Nurses.
There are three components: an internally assessed electronic Portfolio of Evidence built in your dental setting, an externally set and marked online Knowledge Test made up of multiple-choice questions, and an online Professional Discussion with an NEBDN examiner.
The Knowledge Test is 65 multiple-choice questions in 90 minutes, sat online through the MaxExam platform. It must be passed before you attempt the final assessment.
Yes. NEBDN requires learners to be working with an NEBDN-approved training provider, and the Portfolio of Evidence has to be built from real experience in a dental setting, so you need a placement or job alongside the course.
There are two separate costs. NEBDN charges an exam and registration fee — £525 at the time of writing — and your training provider charges tuition on top, typically around £1,400, with some all-inclusive packages near £1,735. Resit and late-deferral fees are charged separately; NEBDN's late-deferral fee is £150 if you defer within four weeks of the Knowledge Test. Always check current fees with NEBDN and your provider.
NEBDN does not publish a pass mark for the Knowledge Test. Treat any figure you see quoted online with caution. A sensible working target is to be scoring comfortably above 70% in practice before you sit it, but that is a preparation benchmark rather than an official threshold.
Yes. Providers generally continue to support learners who do not pass at no extra tuition cost, but NEBDN charges a separate resit examination fee. Check the current fee and the resit windows with NEBDN directly.
You can apply to register with the General Dental Council as a Dental Nurse. From there, routes include Practice Manager, Lead Dental Nurse, and NEBDN post-registration qualifications in areas such as radiography, oral health education, sedation and orthodontic nursing.
