UKMLA vs PLAB 2: What's the Difference and Which Applies to You?

UKMLA vs PLAB 2 is a confusing comparison because they are not really two different exams. PLAB 2 is how international medical graduates (IMGs) sit the practical half of the UK Medical Licensing Assessment (UKMLA), while UK medical students sit the practical half as their school's CPSA. Same GMC standard, same underlying content map, two different delivery routes. This guide sets out who sits what, how the formats differ, and which one applies to you.

If you are a UK student, start on the UKMLA CPSA hub. If you are preparing for the GMC-delivered exam, start on the PLAB 2 hub.

Who sits the UKMLA, and who sits PLAB?

The UKMLA is the single licensing standard the GMC uses to decide who can practise medicine in the UK. Everyone aiming for a licence has to meet it, but the route to it depends on where you trained:

• UK medical students sit the UKMLA as two components run through their own medical school: the Applied Knowledge Test (AKT) and the Clinical and Professional Skills Assessment (CPSA).
• International medical graduates (IMGs) who did not train at a UK medical school typically sit the UKMLA via the PLAB route: PLAB 1 (knowledge) and PLAB 2 (clinical and professional skills), delivered directly by the GMC.

So "UKMLA vs PLAB 2" is not really a contest between two exams. PLAB 2 is one of the two ways the practical component of the UKMLA gets delivered, alongside the CPSA. If you are unsure which route applies to you, the GMC's MLA pages set out eligibility clearly and are the authoritative source to check.

The shared MLA Content Map

Whichever route you sit, the underlying content is the same. The GMC's MLA Content Map defines the presentations, conditions and skills that both the knowledge and clinical components draw on, whether you meet them via the AKT and CPSA or via PLAB 1 and PLAB 2. This matters practically: IMGs preparing for PLAB do not need a separate "PLAB syllabus" mindset, and UK students do not need to treat the CPSA as unrelated to what IMGs are tested on. Our guide to using the MLA content map to revise applies to both routes.

How does a university CPSA differ from PLAB 2 in format?

Both are OSCE-style assessments: you move through a series of timed stations, often with a simulated patient, being assessed on clinical and professional skills. The differences are mostly about who runs the exam and the logistics that follow from that, rather than the underlying skills being tested.

• PLAB 2 is delivered directly by the GMC at its own assessment centre, to a single, consistent national format. It is widely published as having around 16 scored stations, each roughly 8 minutes long. Always confirm the current details on the GMC's MLA pages, since format details are set and updated by the GMC.
• A university CPSA is delivered by each UK medical school to GMC standards, rather than as one national sitting. This means station counts and timing vary by institution. Publicly, schools commonly run somewhere in the range of 8 to 16 stations of around 10 minutes each, but this varies genuinely between schools and even between sittings, so treat any specific number you see online, including here, as indicative rather than fixed. Your own school's assessment handbook is the only source that tells you your actual format.

What does not vary is the underlying principle: both are benchmarked to the same safe-practice standard, both sample across the breadth of clinical and professional skills, and both aggregate performance across multiple stations rather than relying on one high-stakes moment.

Same standard, different delivery

It is worth being explicit about what "same standard" means here. The GMC does not grade PLAB 2 candidates and CPSA candidates differently. Both are assessed against the standard expected of a safe, newly qualified doctor. The differences between the two routes are administrative: who writes and runs the stations, where you sit them, and the exact circuit shape, not what "good enough" looks like clinically or in communication.

This is genuinely useful to know if you are an IMG comparing notes with a UK final-year student, or vice versa. You are not preparing for a softer or harder version of the same thing. You are preparing for the same underlying competencies through a different logistical route.

Which prep resources suit each route?

Because the content map and standard are shared, most good preparation resources work for both routes, with a few practical differences in emphasis:

• For UK CPSA candidates, prioritise your own school's published format and mark scheme details first, since these vary by institution, then build broad content-map coverage and station practice on top. Our CPSA station types guide and CPSA mark scheme guide are a good starting point.
• For PLAB 2 candidates, the format is nationally consistent, so you can prepare directly against the published GMC structure. Our how to pass PLAB 2 guide and PLAB 2 common mistakes guide cover this in detail.
• For both, the highest-yield preparation is the same: practising full stations out loud under timed conditions, with structured feedback across clinical, interpersonal and professionalism domains, rather than passive reading. Realistic AI voice patients and timed mock exams work for either route, because the underlying skills being drilled do not change.

Which one applies to you?

Use this quick decision guide:

• You are studying at a UK medical school and will graduate from it. You sit the AKT and CPSA through your school. This is the UKMLA CPSA route. PLAB 2 does not apply to you.
• You trained at a medical school outside the UK and are seeking GMC registration. You are likely on the PLAB route, sitting PLAB 1 and then PLAB 2, delivered by the GMC.
• You are unsure which route applies to you, for example because of a mixed training background or a recent change in circumstances, the GMC's own eligibility guidance on its MLA pages is the definitive source, not general guidance like this article.

Final thoughts

UKMLA vs PLAB 2 is less a comparison of competing exams and more a question of delivery route to the same standard. UK medical students meet the practical half of the UKMLA through their school's CPSA; IMGs typically meet it through the GMC-delivered PLAB 2. The content map, the standard, and the underlying skills are shared, even though station counts, timing and logistics differ by route and, for the CPSA, by school. Confirm your exact format with your medical school or the GMC's MLA pages, then prepare against the shared content map either way. Start on the UKMLA CPSA hub or the PLAB 2 hub, depending on your route.
