What is OET? Plain-English guide

If you trained in medicine, nursing, dentistry, or another regulated healthcare profession and you are looking at registering somewhere your first language is not the working language, you will almost certainly run into three letters: OET.

The Occupational English Test is the English-language proficiency test built specifically for healthcare professionals. It is owned by Cambridge Boxhill Language Assessment, accepted by regulatory bodies in the UK, Australia, New Zealand, Ireland, Singapore, Malta, Dubai, Namibia, and a growing list of others, and required by most of them as evidence that you can do your job in English without putting patients at risk.

This guide is the one-page version. If you came in not knowing what OET stood for, by the end you will know what it tests, who needs it, and where it sits compared with IELTS and PTE.

Who needs OET?

OET was built for and is accepted in 12 healthcare professions:

• Medicine
• Nursing
• Dentistry
• Dietetics
• Occupational Therapy
• Optometry
• Pharmacy
• Physiotherapy
• Podiatry
• Radiography
• Speech Pathology
• Veterinary Science

If you are in any of those professions and registering in a country that does not consider your prior education delivered in English, you almost certainly need OET (or a regulator-approved alternative, usually IELTS Academic).

For a country-by-country list of regulators that accept OET, see OET accepted countries.

What does the test look like?

OET has four sub-tests, taken in the same sitting:

| Sub-test | Length | Format | |---|---|---| | Listening | ~50 min | Audio recordings of healthcare scenarios + questions | | Reading | 60 min | Three parts — fast-skim, multiple matching, two long texts | | Writing | 45 min | Profession-specific letter (referral, discharge, etc.) | | Speaking | ~20 min | Two 5-minute role-plays with an interlocutor |

Listening and Reading use shared test material across professions. Writing and Speaking use profession-specific material — a nurse gets nursing scenarios, a vet gets veterinary scenarios.

Each sub-test is scored from 0 to 500. Each numeric score maps to a band letter (A, B, C+, C, D, E), with B (350+) being the threshold most regulators require for the Speaking sub-test. For the full breakdown of how the bands work, see OET band scores explained.

Why is OET harder than it looks?

People who arrive at OET assuming "it's basically IELTS for nurses" usually get burned in one place: Speaking. The sub-test is not a conversation about your hobbies. It is a 5-minute, time-pressured, patient-facing simulation in which you have to:

1. Greet the patient and build rapport
2. Elicit symptoms while showing empathy
3. Explain something clinical without using jargon
4. Cover 4–5 task cues from a role-card you saw 3 minutes ago
5. Close politely while running down the clock

You are scored on nine criteria simultaneously — four linguistic (intelligibility, fluency, appropriateness, grammar) and five clinical (relationship building, patient perspective, structure, info gathering, info giving). If you over-rotate on grammar, you lose marks on empathy. If you over-rotate on empathy, you may forget to cover a task cue. The skill that gets tested is not English fluency in the abstract — it is fluency under clinical-consultation load.

This is why we built OET Live. The Speaking sub-test is the part of OET where you most benefit from doing real, live role-plays with feedback, and the part that is hardest to replicate alone with a textbook.

How does OET differ from IELTS?

The short version: IELTS Academic tests general academic English. OET tests healthcare-context English. If you are a healthcare professional, OET is usually easier to score well on because the vocabulary, scenarios, and tasks match what you do every day. You are not asked to write a letter to your local council about a community pool. You are asked to write a referral letter — which you do for a living.

What's a passing score?

The most common minimum across regulators is Band B (350) in all four sub-tests, sometimes with one C+ allowed. Some regulators are stricter; some allow score-aggregation. Always check the current requirements with the regulator you are registering with — they update them.

How long does the result last?

OET results are typically valid for 2 years for most regulators, though some accept older results if you can show continuous English-language clinical work. Again: confirm with your regulator.
