Short answer: the GMC requires IELTS Academic with an overall band of 7.5 and no individual skill below 7.0, achieved in a single sitting. OET at Grade B in all four sub-tests is the accepted alternative. A 6.5 in one skill fails the standard no matter how high the overall score is.

The requirement, precisely
| Requirement | What the GMC asks for |
|---|---|
| Module | IELTS Academic (not General Training) |
| Overall band | 7.5 |
| Each skill | 7.0 minimum — Listening, Reading, Writing, Speaking |
| Sitting | A single test date; skills cannot be combined across sittings |
| Alternative | OET Grade B (350 or above) in all four sub-tests |
Why the "single sitting" rule hurts so much
Several regulators let candidates combine their best skills across two recent tests. The GMC does not. Every one of your four skills has to clear 7.0 on the same test date, and your overall on that date has to be 7.5 or higher.
This changes preparation strategy completely. If you sit the test with three skills comfortably at 8.0 and Writing hovering around 6.5, you cannot bank the three strong results and re-take Writing alone.
You re-sit everything — the full fee, the full day, and the risk that a skill which was 8.0 last time comes back 7.5 while the Writing finally clears.
The practical consequence: do not book the test until your weakest skill is reliably above the threshold in practice conditions. Sitting early "to see where I am" is far more expensive for GMC candidates than for almost anyone else taking IELTS.
The 7.5 overall and the 7.0 floor are two separate hurdles
Both must be met, and candidates fail on each of them in different ways.
Failing the floor: Listening 8.5, Reading 8.0, Speaking 8.0, Writing 6.5 averages to 7.75, which rounds to an overall 8.0 — comfortably above 7.5. It still fails, because Writing is below 7.0.
Failing the overall: a flat 7.0 in all four skills clears every individual minimum but averages exactly 7.0, below the 7.5 overall. It also fails. To reach 7.5 overall you need real headroom somewhere — in practice, at least two skills at 7.5 or above.
That second case surprises people, because "7.0 in everything" sounds like it satisfies a "nothing below 7.0" rule. It satisfies the floor and misses the overall.
Writing is where doctors lose it
Across healthcare candidates, Writing is the skill that most often sits half a band below the rest.
The reason is structural rather than linguistic: IELTS Academic Task 1 asks you to describe a chart, graph or process in 150 words, which is a genre most clinicians have never written in.
Clinical documentation trains precision and brevity; Task 1 rewards a specific shape — overview first, then grouped comparisons, no interpretation of causes.
Task 2 is closer to familiar ground but has its own trap: doctors frequently write a well-argued essay that does not answer the exact question asked. Task Response is a full quarter of the Writing mark, and a strong essay on an adjacent question scores badly.
If you are preparing for the GMC and have limited time, the highest-return allocation is usually: most of it on Writing, a smaller block on whichever of Listening or Reading is weaker, and Speaking practice with a person rather than alone.
IELTS or OET?
| IELTS Academic | OET | |
|---|---|---|
| GMC requirement | 7.5 overall, 7.0 each skill | Grade B in all four sub-tests |
| Content | General academic English | Healthcare-specific scenarios |
| Writing task | Chart description + discursive essay | A referral or discharge letter |
| Availability | Very wide global network | Narrower, but growing |
| Wider use | Accepted for visas and study too | Healthcare registration only |
The genuine argument for OET is that its Writing task — a referral letter — is something a doctor already knows how to write. The genuine argument for IELTS is availability, cost, and the fact that the result is useful for other purposes such as a visa or a course application.
A reasonable rule: if your English is broadly strong and Task 1 chart description is the only thing standing between you and the score, OET removes exactly that obstacle. If your English needs general work, the test format will not rescue you and IELTS is the more practical choice.
A realistic preparation sequence
- Sit one full, timed IELTS Academic practice test. Do not book the real one yet.
- Check both hurdles separately: is every skill at 7.0, and is the overall at 7.5?
- Get your Writing marked against the four official criteria. "It reads well" is not a diagnosis; a criterion breakdown is.
- Spend most of your time on the weakest skill until it clears 7.0 with margin, since you get no partial credit for the others.
- Re-test the full profile in one sitting, under time, before you pay for the real thing.
