What Is OET and Why Do International Nurses Need It for NMC Registration

If you trained as a nurse outside the UK and you want to register with the Nursing and Midwifery Council, you will almost certainly need to pass the Occupational English Test – known as OET. It is one of two English language qualifications the NMC accepts for internationally trained healthcare professionals, and for nurses specifically, it is the test that best reflects the kind of language you will actually use on the ward.

OET is designed and produced by Cambridge Boxhill Language Assessment. Unlike general English tests such as IELTS, every scenario in OET is set in a healthcare environment. The reading texts are clinical documents, the listening recordings are patient consultations, and the writing task requires you to produce a professional healthcare letter. That specificity matters because it means good preparation for OET is also good preparation for working in the NHS.

This guide explains what OET involves, what the NMC requires, and why the Writing component is the part that most internationally trained nurses find hardest.

What OET covers

OET has four sub-tests: Listening, Reading, Writing, and Speaking. You sit all four in a single exam session. Each sub-test is scored on a scale from A (the highest) down through B, C+, C, D, to E.

The NMC requires you to achieve a minimum of Band B in each of the four sub-tests. A score of Band B means you have demonstrated the level of English needed to communicate safely and professionally in a healthcare setting. Falling short of Band B in even one sub-test means you will need to retake that component.

• Listening (50 minutes) – healthcare consultations and workplace dialogues
• Reading (60 minutes) – clinical texts and healthcare workplace documents
• Writing (45 minutes) – produce one professional healthcare letter based on a set of case notes
• Speaking (approximately 20 minutes) – two role-play consultations with an interlocutor

Why the Writing sub-test causes the most problems

Most internationally trained nurses who come to us have passed their Listening and Reading components. Writing is where they get stuck, and there are consistent reasons for that.

The Writing test gives you a set of case notes – detailed patient information including medical history, recent treatment, current medication and observations – and asks you to write a professional healthcare letter based on those notes. That might be a referral to a specialist, a discharge summary sent to a GP, or a transfer letter to another facility. You have 45 minutes.

The difficulty is that writing a professional healthcare letter in English is a specific skill that most nurses – even those with strong conversational English – have not practised formally. The register required (that is, the level of formality and the professional tone appropriate to healthcare correspondence) is different from spoken clinical English, and it is very different from the academic English that many nurses learned during their training. Getting the register right while also selecting the right information from the case notes, organising it logically, and completing the letter within the time limit is genuinely challenging.

What the NMC actually requires

The Nursing and Midwifery Council requires internationally trained nurses to demonstrate their English language proficiency as part of the registration process. The accepted tests are OET and IELTS. For nurses, the NMC specifies:

• OET: minimum Band B in all four sub-tests
• IELTS Academic: minimum overall score of 7.0 with no individual band below 6.5
• Results must be no more than two years old at the point of application

The NMC also accepts the English language proficiency demonstration pathway, which involves a supervised practice period, but this is a separate route and is not covered in this article.

OET is generally considered the more natural choice for nurses because the content is healthcare-specific. A nurse who has been working clinically for years will find the scenarios in OET far more familiar than the academic and general content in IELTS. That familiarity does not guarantee a pass, but it means the effort you put into OET preparation is directly relevant to your day-to-day clinical work.

How OET Writing is assessed

OET Writing is assessed against four criteria. Understanding these will help you focus your preparation in the right areas.

• Content – have you included the relevant information from the case notes, and is it accurate? This is worth 40% of your score.
• Conciseness and Clarity – is the letter focused and free of unnecessary detail? Healthcare letters need to communicate quickly and clearly.
• Genre and Text Organisation – does the letter follow the conventions of the letter type requested? Is it structured logically?
• Language – is your grammar, vocabulary and spelling accurate? Does the language suit the professional healthcare context?

Content carries the most weight, which means one of the most common reasons for falling short of Band B is including too much or too little information from the case notes. Selecting what is clinically relevant to the reader – and leaving out what is not – is a skill that takes deliberate practice to develop.

Is OET harder than IELTS?

This is the question most internationally trained nurses ask first. The honest answer is that neither test is objectively harder – they are different, and which one suits you depends on your background and your strengths. If you have been working clinically for several years, the healthcare scenarios in OET will feel natural. If you have strong academic reading and writing skills, IELTS may be more comfortable.

What we consistently see at Functify Learning is that nurses who attempt OET Writing without targeted preparation underestimate how specific the marking is. The letter needs to be not just grammatically correct but professionally appropriate in tone, accurately selective in content, and clearly structured according to healthcare letter conventions. That requires practice with feedback – not just general writing practice.

Next steps

If you are preparing for OET Writing, the most effective thing you can do is get structured feedback on your letters from someone who understands both the healthcare context and the OET marking approach. Reading about the test is useful, but writing practice letters and having them reviewed against the actual assessment criteria will move you forward faster than any other approach.
