The headline is real and deserves careful handling: official GMC data show the PLAB 1 pass rate falling from 74.1% in 2021 to 62.2% in 2025, with PLAB 2 recording 59.8% in 2025. A twelve-point fall over five years is a genuine signal, it has generated genuine anxiety, and it has generated explanations the data cannot support. This analysis, part of our official-data series and built on the methodology at /blog/what-medical-exam-pass-rates-can-and-cannot-tell-you, separates the three cleanly: what the figures show, what they cannot establish, and what a candidate preparing now should actually do differently. Figures as published by the GMC, checked 29 August 2026.
What the data shows
Three facts sit securely in the official record. The direction: PLAB 1 pass rates have declined across the five-year window, from 74.1% to 62.2%, a move large enough and sustained enough to sit outside ordinary year-to-year wobble. The companion figure: PLAB 2's 59.8% in 2025 means the practical examination now passes a smaller share than folklore assumes, and candidates budgeting attention only for Part 1 are misreading the pathway. And the context every percentage needs: candidate volumes through PLAB have been historically large in this period, which matters twice over, because absolute numbers of unsuccessful candidates are correspondingly large, and because rapidly growing cohorts are exactly the circumstance in which composition, who is sitting, changes fastest.
What the data cannot establish
Aggregate pass rates carry no information about several things routinely read into them. Candidate preparedness: the data does not distinguish well-prepared from underprepared candidates, so "standards among applicants fell" is speculation wearing a statistic. Attempt mix: first-time and repeat candidates pass at structurally different rates, and a shifting mix moves the aggregate without any change in examination or candidates' quality; the published aggregate does not decompose this for us. Training background and route: the cohort's composition across medical schools, regions and preparation circumstances is unobserved in the headline figure. Resource quality: no aggregate movement can indict or credit any preparation resource, in either direction, and analyses that attribute the fall to particular banks or courses are marketing, not inference. And causation generally: the period spans the MLA framework's development and unprecedented application volumes, plausible contributors both, and the honest position is that the aggregate data cannot apportion the fall among cohort growth, composition shift and assessment evolution. Plausibility is not attribution.
The MLA context
PLAB now sits within the MLA framework, and one forward-looking fact matters more than any retrospective explanation: the updated MLA content map applies to assessments from September 2026, which makes explicit map alignment a checkable property of preparation rather than a slogan. Candidates preparing now are preparing for the current examination under the current map, and the productive question is not "why did 2025 fall?" but "is my preparation aligned to what is actually assessed from next month?", a question with an actionable answer: /blog/ukmla-content-map-september-2026-changes.
What candidates should do, and not overreact to
Do: treat the base rate as a seriousness signal, a 62.2% examination is failed by well over a third of sitters and deserves months, not weeks; prepare against the September 2026 map explicitly; weight PLAB 2 properly from the start, because 59.8% says the practical examination is not a formality; and judge your own readiness by the signals that predict, stable unseen-question performance, blueprint coverage and timed mocks, per /blog/why-qbank-percentages-are-not-comparable, rather than by the cohort's history. Do not: choose sittings on difficulty rumours, which standard-setting is designed to neutralise; assume the fall means the examination is capricious, since a maintained standard with a changing cohort produces exactly this pattern; or let a base rate personalise into fatalism, because you are not a random draw from the cohort, and preparation moves individual probability far more than any aggregate moves.

Frequently asked questions
Is PLAB getting harder?
The data shows lower pass rates, not a raised standard; distinguishing a harder examination from a changed cohort requires decompositions the public aggregate does not provide, and confident answers in either direction outrun the evidence.
Does the fall change how many attempts I should plan for?
Plan seriously for one: the base rate justifies thorough preparation, not budgeted failure; what it does justify is honest self-assessment before booking, since sitting underprepared is the one avoidable contribution to next year's denominator.
Where are the official figures?
The GMC publishes PLAB pass-rate data directly; read it at source, with denominators, and treat any summary, including this one, as a signpost to it.
Do the figures differ for first-time sitters?
First-attempt rates run structurally higher than aggregates that include repeats, which is one more reason not to read the headline number as personal probability; where the GMC publishes decomposed figures, they are the better planning reference.
