What Is the NMC CBT Exam and How Do You Pass It?

If you are an internationally educated nurse planning to work in the UK, the Computer-Based Test (CBT) is your first formal step towards NMC registration. Despite its importance, many candidates are unsure what the exam involves, how it is structured, and how to prepare for it effectively.This guide answers all of that clearly and concisely.

 


What Is the NMC CBT?

The CBT is a theory-based examination set by the Nursing and Midwifery Council (NMC). It assesses whether your nursing knowledge and clinical decision-making meet UK standards.

It forms part of the Test of Competence (ToC), which consists of two stages:

For most internationally educated nurses, the CBT is the first formal hurdle after submitting eligibility documents to the NMC.

 

Who Needs to Take It?

The CBT is required for:

  • International nurses applying for NMC registration

  • Nurses returning to practice after a significant gap (in some cases)

 

Exam Structure at a Glance

The CBT is divided into two parts.

Part

Focus

Duration

Questions

Part A

Numeracy

30 minutes

15

Part B  

Clinical knowledge

2 hours 30 minutes

100

 

Both parts must be passed independently.

 

Part A: Numeracy

This section tests the calculations you would perform in everyday clinical practice, including drug dosage calculations, infusion rates, and unit conversions. The level of difficulty is not advanced, but accuracy is critical. A small arithmetic error can cost you the answer.

 

Part B: Clinical Questions

This is the core of the exam. You will answer 100 multiple-choice questions based on adult nursing scenarios, covering clinical decision-making, patient safety, and applied nursing knowledge.

 

Questions are scenario-based rather than straightforward recall. You are expected to identify the most appropriate action, priority intervention, or safest response according to UK clinical standards. Sound judgement matters as much as knowledge.

 

What Does the Syllabus Cover?

The CBT syllabus spans several interconnected areas of nursing practice, including:

  • Professional values and ethics

  • Communication and interpersonal skills

  • Clinical decision-making and assessment

  • Leadership and team working

  • Adult health conditions and nursing interventions

A key point: a single question can test multiple areas at once. Rather than studying topics in isolation, aim to understand how clinical knowledge, communication, and patient safety principles work together in practice.

 

Passing Score and Results

The passing score is not published as a fixed percentage and may vary depending on the sitting. What is consistent is that each part must be passed separately.

Results are typically available within 48 hours of completing the exam. No question-level feedback is provided, as the NMC does not release this information in order to protect the integrity of the assessment.

 

Resits and Attempt Limits

Candidates are permitted up to three attempts per application, with a minimum gap of 10 days between each sitting.

If all three attempts are unsuccessful, the application is closed. You must then wait at least six months before reapplying.

This makes early, structured preparation essential. Repeated attempts do not just take time; they can delay your entire registration timeline.

 

How Long Is the CBT Valid?

Once passed, your CBT result remains valid for up to two years. Within this period, you are expected to complete the remaining steps in the registration process, including the OSCE.

 

The booking process begins once the NMC confirms your eligibility. The steps are straightforward:

 

  1. Receive your authorisation to test from the NMC

  2. Select an approved test centre and available date

  3. Pay the required exam fee

  4. Confirm your booking

 

Only book when you feel genuinely prepared. An early failed attempt can set back your timeline and affect your confidence going into subsequent sittings.

 

How to Prepare Effectively

Given the scenario-based format, passive reading alone is rarely sufficient. Effective preparation usually involves:

  • Practising with mock questions – focusing on clinical reasoning, not just factual recall

  • Understanding UK nursing standards – familiarise yourself with how the NMC expects nurses to prioritise care

  • Working on numeracy regularly – consistent practice reduces the risk of calculation errors under exam conditions

  • Reviewing the NMC Code – many questions are rooted in professional values and ethical responsibilities

 

Final Thoughts

The NMC CBT is a manageable exam when approached with the right preparation strategy. Understanding the structure, knowing what the questions demand, and practising consistently will put you in a strong position on the day.
