The NMC Computer-Based Test (CBT) is the first formal gate between you and a registered nursing career in the UK. Pass it, and you can begin applying to NHS Trusts for a fully employer-sponsored relocation package. Fail to prepare properly, and you lose time, money, and momentum.
This guide covers exactly what the exam tests, how it is structured, and how to prepare so you pass on the first attempt.
What This Guide Covers
1. What the NMC CBT Actually Tests
The CBT is Part 1 of the NMC Test of Competence (ToC). It assesses whether your theoretical nursing knowledge meets UK healthcare standards before you are permitted to practise clinically in Britain.
The most important thing to understand: the exam is based entirely on UK nursing standards and protocols, not your home country’s guidelines. Many candidates with strong clinical backgrounds still fail because they answer questions based on what they were trained to do at home rather than what the NMC Code of Professional Standards and UK clinical frameworks require.
2. Exam Format and Structure
The CBT consists of two parts taken in a single sitting at an authorised Pearson VUE test centre in your home country. Total duration is approximately 3 hours.
| Part | Content | Questions | Time Allowed |
|---|---|---|---|
| Part A: Numeracy | Drug dosage calculations, IV flow rates, fluid balance, unit conversions | 15 short-answer questions | 30 minutes |
| Part B: Clinical Knowledge | Patient assessment, care planning, pharmacology, professional ethics, patient safety, UK nursing practice | 100 multiple-choice questions | 2 hours 30 minutes |
Both parts must be passed in the same sitting. Passing Part B alone does not count if Part A is failed, and vice versa. The CBT exam fee is £83, paid directly to Pearson VUE when booking. Most NHS Trusts reimburse this cost as part of the relocation package after you arrive and pass your OSCE.
3. Before You Can Book
You cannot book the CBT independently. The following must be in place first:
- Submit your application through the NMC Online portal and pay the evaluation fee
- Receive your NMC eligibility letter confirming you meet qualification and registration standards
- Select the correct exam code matching your nursing field (adult, mental health, paediatric, learning disability, midwifery). Choosing the wrong code means your result may not be accepted
Once you receive the eligibility letter, Pearson VUE will email you with account details to book your test date and centre. Full booking guidance is available on the Pearson VUE NMC page.

4. How to Prepare: Study Plan and Resources
Start with the Official NMC Blueprint
The NMC CBT blueprint is a publicly available document that outlines every topic area and competency the exam covers. Download it from the NMC website and use it as your study framework. Do not study topics the blueprint does not cover, and do not skip anything it does.
Take the Free Official Practice Tests
Pearson VUE provides free official CBT practice tests that replicate the exact format of the live exam. The numeracy practice test is 15 questions (30 minutes) and the clinical practice test is 50 questions (1 hour 15 minutes). These are accessible without booking and can be retaken unlimited times. Use them at the start of your preparation to benchmark your level, then again in the final week before your exam.
Access them directly on the Pearson VUE NMC practice tests page.
Core Study Resources
- The Royal Marsden Manual of Clinical Nursing Procedures: the standard UK clinical reference. CBT Part B questions are closely aligned to its guidelines
- NMC Code of Professional Standards: essential for ethics and professional practice questions
- NICE guidelines: for evidence-based practice questions covering common conditions
- CBT-specific question banks: platforms such as StudyPRN offer 400+ practice questions mapped to the NMC blueprint with full answer explanations
Suggested Study Schedule
- Weeks 1 to 2: Read the NMC blueprint. Complete the free Pearson VUE practice tests to identify weak areas
- Weeks 3 to 6: Study Part B topics domain by domain. Do 20 to 30 practice questions daily. Focus on UK-specific protocols, not general nursing theory
- Daily throughout: Practice 5 drug calculation questions every morning. Accuracy in Part A is non-negotiable
- Final week: Full mock exam under timed conditions. Review every incorrect answer
5. Exam Day: What to Expect
- Bring your valid passport. It must match the passport on your NMC Online account
- Arrive at the Pearson VUE test centre at least 15 minutes early
- No study materials are permitted inside the exam room
- Part A and Part B are taken consecutively with a short optional break between them
- Results are emailed within 48 hours of completing the exam
- You will receive either a pass or fail. No numerical score is provided
6. After You Pass
Your CBT result is automatically added to your NMC profile. From this point, you have two years to complete the OSCE practical exam in the UK. The CBT pass is also the signal to begin applying to NHS Trusts for employer-sponsored work permits. Most Trusts require confirmation of your CBT pass before issuing a job offer and initiating the Health and Care Worker Visa process.
