Differential attainment and the MSRA: what the data says (and doesn’t)

If you have spent any time in IMG forums you will have met the statistic in its scariest clothing: international graduates score lower on average in UK selection exams, including the MSRA. It is true, it deserves to be discussed honestly — and it is routinely presented in ways that mislead in both directions. Here is a calmer reading of what the evidence says, what it does not say, and what it means for one person: you.
What the data shows
Across UK postgraduate assessments, a consistent average gap exists between UK graduates and IMGs — the literature calls it differential attainment. It appears in knowledge tests but is most pronounced in situational judgement formats like the MSRA’s Professional Dilemmas paper, and it persists after adjusting for many candidate factors. This is a well-replicated group-level finding, documented in peer-reviewed work (including in the BJGP) and acknowledged by the GMC and the colleges. Pretending it away helps nobody.
What the data does not show
- It does not show a capability difference. The literature’s own best explanations are contextual: familiarity with UK workplace culture, the linguistic register of SJT options, unequal access to the informal preparation networks UK graduates inherit, and the plain fact that these tests are written inside the culture they examine.
- It does not predict any individual. The distributions overlap heavily: large numbers of IMGs outscore large numbers of UK graduates every single round. An average gap is a statement about groups, not a ceiling on you.
- It is not fixed. The components with the strongest evidence behind them — cultural familiarity and format practice — are precisely the trainable ones. NHS work experience and structured SJT practice both track with narrower gaps.
Because the alternative is worse. Doctors who meet the statistic unprepared tend to read a weak first practice score as a verdict; doctors who understand it read the same score as a starting line with a known, closable cause. The framing changes behaviour, and behaviour changes the score.

What genuinely narrows the gap
Time inside the system
NHS experience is the strongest practical leveller — it converts the PD paper from an abstract culture quiz into scenes from your working week. This aligns, usefully, with what the 2026 rules reward anyway.
Deliberate format practice, early
SJT performance responds to structured practice with reasoned feedback — not because you memorise answers, but because you internalise the principle order the format rewards. The PD guide sets out the method; our free Professional Dilemmas Reasoner supplies the reps.
Studying the culture as content
Good Medical Practice, duty of candour, escalation norms, safety-netting language: written-down, finite, learnable. The IMG Hub exists to make this layer explicit instead of inherited.
Hold both truths at once: the gap is real and worth naming, and it is a familiarity gap that thousands of IMGs close every year — half of 2024’s first-year GP trainees qualified outside the UK (House of Commons Library, January 2026), and they came through these same exams. Respect the statistic; refuse the verdict.
Work on the closable part
Structured, reasoning-first practice is the best-evidenced way to close a familiarity gap. It is what everything we build is for.
