PLAB is the most common route for international medical graduates (IMGs) into UK medical practice — but it's frequently confused with GMC registration itself, when it's actually just one input into that registration. This guide covers what PLAB actually tests, how the two parts are structured, the English-language bar you must clear before you can even book it, and what happens after you pass.
What PLAB Is
PLAB (Professional and Linguistic Assessments Board) is the GMC's two-part examination for IMGs who don't otherwise qualify for GMC registration through an alternative route (such as holding a primary medical qualification from a small number of exempted countries, or via specialist/Royal College routes). Passing both parts of PLAB is evidence that your clinical knowledge and skills meet the standard expected of a doctor starting UK practice — it is not itself GMC registration, but a required step toward it for most IMGs.
PLAB 1 — Written Exam
| Detail | Value |
|---|---|
| Format | Computer-based, single-best-answer multiple-choice questions |
| Number of questions | 180 |
| Duration | 3 hours |
| Content | Scenario-based clinical questions across medicine, surgery, paediatrics, obstetrics & gynaecology, psychiatry, and ethics/law |
| Where it's held | Multiple international test centers, including several in India |
PLAB 2 — Clinical (OSCE) Exam
| Detail | Value |
|---|---|
| Format | Objective Structured Clinical Examination (OSCE) |
| Number of stations | 16 |
| Time per station | 8 minutes |
| Content | History-taking, examination, counselling, breaking bad news, ethics, practical procedures, and clinical management scenarios |
| Where it's held | Exclusively at the GMC's clinical assessment centre in Manchester — there is no international venue for PLAB 2 |
Confirm current fees and exact dates directly at gmc-uk.org before booking — PLAB fees are reviewed periodically (for reference, recent published figures put PLAB 1 at roughly £280–£285 and PLAB 2 at roughly £1,000–£1,100, but treat these as approximate and verify the current figure before paying).
The English-Language Requirement — Required Before You Can Even Book
This is a common failure point: you need a valid English-language score before you can book PLAB 1, not just before final GMC registration.
| Test | GMC Minimum |
|---|---|
| IELTS Academic | Overall 7.5; every individual component (Listening, Reading, Writing, Speaking) at least 7.0 |
| OET (Medicine) | Grade B in all four sub-tests |
| TOEFL iBT | Overall 95; Listening 24, Reading 24, Speaking 23, Writing 27 |
The per-component minimum is absolute for IELTS. A 7.5 overall score with any single skill below 7.0 does not meet the GMC requirement — this catches candidates who have a strong overall average but one weaker skill (Writing and Speaking are the most common shortfalls for doctors moving from clinical documentation into essay-style academic writing and abstract discussion).
IELTS Academic is required specifically — IELTS General Training is not accepted. Score validity for GMC purposes is 2 years from the test date, and your score must remain valid through PLAB 1, PLAB 2, and your eventual registration application.
This matches the same GMC threshold used elsewhere for GMC-bound doctors — verify the current figures directly at gmc-uk.org, since English-language thresholds are reviewed periodically.
The Full Pathway: PLAB Pass to GMC Registration
| Step | What Happens |
|---|---|
| 1. English-language evidence | Achieve the GMC's IELTS/OET/TOEFL minimum — required before booking PLAB 1 |
| 2. PLAB 1 | Pass the 180-question written exam |
| 3. PLAB 2 | Pass the 16-station OSCE in Manchester |
| 4. Apply for GMC registration | Submit primary medical qualification evidence, internship/graduation documentation, identity verification, and confirm English-language evidence is still valid |
| 5. GMC registration with a licence to practise | Granted once all documentation is verified |
| 6. Find a UK training or NHS post | Registration alone doesn't guarantee employment — most IMGs then apply for NHS trust posts or specialty training via standard routes |
Timing matters: you generally need to apply for GMC registration within a limited window after passing PLAB 2 (commonly cited as within a few months of your PLAB 2 pass, and your English-language evidence must still be within its validity period at the time you apply) — don't treat passing PLAB 2 as the finish line, since a lapsed English score or a missed registration window can force you to retake requirements. Confirm the exact current window and any recent policy changes directly at gmc-uk.org before planning your timeline.
PLAB vs. Other Routes to GMC Registration
| Route | Who It's For |
|---|---|
| PLAB 1 + PLAB 2 | Most IMGs without an exempting qualification |
| Royal College membership exams (e.g., MRCP, MRCS, MRCGP) | IMGs pursuing a specific specialty route, sometimes combined with or in place of PLAB depending on circumstances |
| Primary qualification from an exempted list | A small number of countries/qualifications exempt from PLAB — confirm current list at gmc-uk.org |
| UK Foundation Programme graduates | UK-trained doctors don't need PLAB |
