IELTS vs OET: Which English Test Do You Need for the NHS?

Before you can register with a UK healthcare regulator and take up an NHS post, almost every internationally trained clinician has to clear one more hurdle that has nothing to do with clinical competence: proving your English is good enough to practise safely. Two tests dominate this requirement — IELTS (International English Language Testing System) and the OET (Occupational English Test) — and candidates spend a genuinely surprising amount of time and money deciding between them, often on the basis of forum hearsay rather than their actual regulator's published requirements. This guide sets out what's really different between the two tests, what each of the four main UK healthcare regulators requires, and how to think about which one suits you.

What IELTS and OET actually test

IELTS Academic is the general academic version of the world's most widely taken English test, run by the British Council, IDP and Cambridge. All four sections — Listening, Reading, Writing and Speaking — draw on general-interest and academic topics: a lecture on urban planning, a passage about renewable energy, an essay on a broad social issue. It wasn't designed for healthcare specifically, which is exactly why OET exists as an alternative.

OET is purpose-built for healthcare. Listening and Reading are common to all candidates but drawn from clinical contexts (a healthcare consultation, a passage about a treatment approach), while Writing and Speaking are profession-specific — nursing, medicine, pharmacy, physiotherapy, dentistry and several other professions each get their own tailored tasks. For the Writing sub-test, for example, a nursing candidate might write a discharge letter based on given case notes, and the Speaking sub-test involves role-playing a realistic patient consultation with a trained interlocutor, rather than a general conversation about your hometown or hobbies.

• • IELTS Academic — general topics across all four skills, one standard version for every profession
• • OET — Listening and Reading drawn from healthcare contexts; Writing and Speaking are profession-specific (nursing, medicine, pharmacy, dentistry, physiotherapy and more)
• • Both are graded independently in each of the four skills — a strong result in one skill can't offset a weak result in another
• • Both require you to book through the official test provider (IELTS via the British Council or IDP; OET via the Cambridge Boxhill Language Assessment Trust) — never through an unofficial intermediary

What each UK healthcare regulator requires

This is the part candidates most often get wrong by relying on generic advice rather than their own regulator's page — because every regulator sets its own score requirement, and they are not identical to one another. What follows is what each regulator's own published guidance said at the time this page was last checked. Treat it as a starting orientation, not a substitute for the regulator's current requirements page.

Nursing and Midwifery Council (NMC)

For IELTS Academic, the NMC has required at least 7.0 in Listening, Reading and Speaking, and at least 6.5 in Writing, with an overall band score of 7.0. For OET, the NMC has required at least Grade B in Listening, Reading and Speaking, with a slightly lower Grade C+ accepted in Writing — a small but genuinely useful concession if writing is your weaker skill. The NMC has also allowed candidates to combine two sittings of the same test (two IELTS, or two OET) within a set time window, rather than requiring every skill to be passed in a single sitting. Confirm all of this on the NMC's English language requirements page.

General Medical Council (GMC)

For IELTS Academic, the GMC has required an overall score of 7.5, with at least 7.0 in each of the four sections. For OET, the GMC has required Grade B (numerically, 350 or above) in all four sub-tests of the Medicine version, generally within a single sitting rather than combined across two. The GMC does not accept TOEFL or PTE for this purpose. Confirm current requirements on the GMC's evidence of English page.

Health and Care Professions Council (HCPC)

The HCPC covers a wide range of allied health professions (physiotherapists, radiographers, paramedics, occupational therapists and more). It has required an overall IELTS score of 7.0 with no individual element below 6.5, or Grade B (350) in each OET sub-test — with a notably higher bar for speech and language therapists specifically (an overall IELTS score of 8.0, with no element below 7.5). The HCPC only began accepting OET relatively recently (from January 2025), which is itself a reminder of how much these requirements can shift — check the HCPC's international applications page for the current position for your specific profession.

General Pharmaceutical Council (GPhC)

For pharmacists, the GPhC has required an overall IELTS Academic score of 7.0 with no component below 6.5 at a single sitting, or Grade B in all four sub-tests of the OET Pharmacy version — unlike the NMC, the GPhC has not offered a lower writing grade concession for OET, so all four sub-tests need to reach the same standard. Check the GPhC's own guidance on evidence of English language skills for the current position.

Cost and format differences

Cost is a genuine practical factor, particularly if you might need to resit. As of when this page was last checked, a full OET (all four sub-tests) cost roughly AUD 587 worldwide — OET publishes and updates its own pricing in Australian dollars regardless of where you sit it, so check the current converted cost on oet.com for your currency and location. Standard IELTS Academic in the UK has cost roughly £155–£220, while the separate IELTS for UKVI version (needed specifically for certain visa applications, not generally for regulator registration) has started from around £257. Both organisations publish current local pricing on their own booking pages, which is the only reliable source since prices vary by country and change periodically.

• ✓ OET can be taken on paper, on computer at a test centre, or remotely via OET@Home — the fee is generally the same across formats
• ✓ IELTS can be taken on paper or on computer, with computer-delivered results typically returned faster (a matter of days rather than the one to two weeks paper-based results can take)
• ✓ Both tests run Listening, Reading and Writing in one sitting; Speaking may be scheduled separately, sometimes on a different day
• ✓ Test centre availability varies a lot by country and city — book well in advance if you're working to a visa or registration deadline

The visa's own English requirement — a separate question

It's worth clearly separating two different English requirements that candidates often conflate: your regulator's requirement (to register with the NMC, GMC, HCPC or GPhC) and the Health and Care Worker visa's own English language requirement, which the Home Office sets independently. Helpfully, for most doctors, nurses, midwives and other regulated staff, meeting your regulator's English requirement as part of registration is generally treated by the Home Office as also satisfying the visa's requirement — you don't necessarily need to sit a separate, visa-specific test. But if you fall outside that exemption for any reason, note that OET is not currently on the Home Office's own list of approved Secure English Language Tests (SELTs) for standalone visa purposes — IELTS for UKVI is the commonly used option there. This is a genuinely important distinction to get right, and the rules have changed before (the Skilled Worker visa's required CEFR level moved from B1 to B2 for new applicants from January 2026, for example), so confirm your own position on gov.uk's Skilled Worker visa English language page and with your sponsoring trust's HR or international recruitment team before assuming either test alone covers everything you need.

How much time to realistically budget

Candidates consistently underestimate how long the whole English-testing stage takes once you factor in preparation, booking lead times, and the possibility of a resit. Test centre capacity for both IELTS and OET varies enormously by country and city — some locations have weekly sittings, others considerably fewer — and popular slots close to visa or registration deadlines can book up weeks or months in advance. On top of the test date itself, most candidates spend anywhere from a few weeks to a few months preparing, depending on how confident they already are with English generally and with the specific test format. If you're aiming for a particular registration or visa timeline, work backwards from that date, build in enough buffer for at least one resit if your first attempt falls short, and book your test slot as early as you reasonably can rather than waiting until your preparation feels "finished" — for many candidates, sitting the real test under real conditions is itself part of what prepares them for a strong second attempt if one is needed.

• • Check test centre availability in your area before committing to a target date — don't assume a slot will be available whenever you're ready
• • Budget financially and emotionally for the realistic possibility of a resit — it's common, not a sign you're not ready for NHS work
• • If your visa or registration process has a hard deadline, build in enough buffer for a second sitting rather than booking your only attempt right up against it
• • Keep a copy of every result you receive, even ones that don't meet the required score — some regulators' supporting-evidence or combined-sitting provisions may still make use of it

So which one should you choose?

Since both tests are accepted by every major UK healthcare regulator, the decision usually comes down to fit rather than acceptance:

• • Lean toward OET if you're already comfortable with clinical vocabulary, case notes and patient-facing scenarios from your current clinical role — the content will feel more like your day job than an abstract exam
• • Lean toward OET if your weakest skill is writing and your regulator (like the NMC, historically) accepts a lower Writing grade for OET than the equivalent IELTS band
• • Lean toward IELTS if you're more confident with general academic English than clinical terminology, or if you already have strong IELTS preparation materials, a tutor, or a study group built around it
• • Lean toward IELTS if you think you might need a Secure English Language Test for visa purposes independent of your regulator, since IELTS for UKVI is a recognised SELT and OET currently is not
• • Either way, sit a full practice test under timed conditions before you book the real thing — both tests are as much about time management and format familiarity as raw English ability

If you're still unsure, many test preparation providers and some NHS trust-run international recruitment pipelines offer a short diagnostic assessment that can indicate which format plays more to your strengths — worth asking your recruiting trust or agency whether they offer this before you commit to either test financially.

If you've already sat one test before deciding to read this

Plenty of candidates land on a guide like this one only after they've already sat IELTS or OET once — sometimes as part of an earlier application to a different country, sometimes on a recruiter's generic advice before their specific regulator's requirement was confirmed. If that's you, don't assume your existing result is wasted. Check your regulator's current validity window (commonly around two years) and, if you're within it and the score meets the requirement, it may simply be usable as-is — there's no general rule requiring you to resit a test purely because time has passed since you first looked into this, provided the result is still within the accepted window and meets the current score requirement. If your existing result falls short in one skill only, check whether your regulator's combined-sitting or narrow-miss provisions (where they exist) might apply before assuming a full resit is necessary. And if you originally sat the "wrong" test for your circumstances — OET when your regulator only wanted IELTS at the time, for instance — checking the current position matters, since policies expanding which tests a regulator accepts (as the HCPC did with OET) can sometimes work in your favour if you check again rather than assuming an old rejection still stands.

Practical preparation tips

A few things candidates who've been through this process consistently report as useful, regardless of which test you choose:

• ✓ Use only official preparation materials from the test provider (British Council, IDP or Cambridge for IELTS; the official OET website) as your primary source — third-party practice tests vary hugely in quality and some are simply inaccurate
• ✓ Practise under real timed conditions, ideally at the same time of day you'll sit the actual test, so pacing becomes familiar rather than something you're managing for the first time on exam day
• ✓ For OET, practise the profession-specific Writing and Speaking tasks for your own profession specifically — a nursing candidate practising medicine-specific sample tasks is preparing for the wrong exam
• ✓ Record yourself for the Speaking component and listen back critically, or find a study partner — most candidates underestimate how much clarity and pacing matter compared with vocabulary alone
• ✓ Book your test with enough buffer before any registration or visa deadline to allow for a resit if needed — test centre slots can book up weeks or months in advance in some locations

Why trust this guide

Where to go from here

Whichever test you choose, the English language requirement is one part of a longer registration and relocation process — pairing this decision with a realistic view of the visa process and the costs involved will serve you better than optimising the test choice in isolation. Above all: check your own regulator's current score requirement directly before you book anything. The numbers in this guide reflect what each regulator published at the time of writing, but the NMC, GMC, HCPC and GPhC all review these requirements periodically, and a stale number could cost you a wasted test fee or, worse, a rejected application. FrontlinePay is an independent site with no affiliation to any of the regulators, test providers or the Home Office named on this page.
