MRCP Part 1 Pass Mark

Part 1 is a best-of-five single best answer paper sat in two three-hour sittings on the same day. Each item is scored right or wrong; there is no negative marking, so an unanswered question can only cost you marks and a considered guess never can.

Your total raw mark is not what is reported. It is converted to an equated score on a scale shared across diets, and the result letter reports that score alongside the pass equated score for the diet, plus a breakdown of your performance by specialty relative to other candidates.

Both papers count towards a single outcome. There is no separate threshold for paper 1 and paper 2, and no requirement to pass individual specialties.

The standard is set by expert judgement of the level of knowledge expected of a doctor at the start of postgraduate physician training — not by deciding in advance how many candidates should pass. Once that standard is established, it is carried forward from diet to diet by equating rather than being re-invented each time.

Is a fixed percentage used?

No. Because each diet draws a different sample of questions from the blueprint, papers are never identically difficult, and a fixed percentage would mean the bar moving with the luck of the draw. Instead the raw score required moves so that the standard does not. A harder paper cannot punish you and an easier one cannot flatter you.

Is it a curve or a quota?

No. Equating anchors to items whose difficulty is already known from previous diets, not to the performance of the candidates sitting with you. You are not competing against the room.

Three consequences of equated scoring matter for how you revise and how you read your result.

• Raw percentages are not comparable. Your mock percentage and another candidate’s exam percentage describe different papers. Trends in your own accuracy over hundreds of questions are informative; a single block percentage is not.
• Every score carries measurement uncertainty. Part 1 reports publish a standard error of measurement of roughly 3%, alongside a reliability (Cronbach alpha) of around 0.93 — high, because the paper is long. A result within a couple of percent of the standard is genuinely borderline, which is an argument for aiming comfortably clear of the line rather than at it.
• Distance from the standard is the useful number. Two points below and forty points below are different problems with different plans.

Reading your feedback report

Look first at your equated score against the pass equated score; then at the specialty profile, picking out the two or three areas clearly below your own average rather than the ones that felt bad; then at consistency between the two papers. A large gap between papers usually points to stamina or pacing rather than knowledge, and full-length timed rehearsal fixes it.

The equated standard is designed to be comparable across diets, and the published pass equated score has been stable at 540 in recent Part 1 performance reports. What varies is the raw performance that reaches it: sit a harder paper and fewer correct answers are needed for the same equated score.

So there is no benefit in trying to pick an “easier” diet, and no penalty for sitting one where the questions felt hard. Because the published values are confirmed diet by diet, quote the pass equated score from the report for the diet you sat rather than from a forum post or a course page.

These two are constantly confused. The pass mark is the standard you personally have to reach — absolute, equated, unaffected by anyone else. The pass rate is the proportion of candidates at a diet who reached it, reported after the event and differing substantially between candidate groups: first attempt versus repeat, UK trainees versus candidates preparing at distance.

A low pass rate does not mean the bar was raised; it describes who sat and how prepared they were. Use pass-rate data for planning context, and your own timed accuracy across the whole syllabus to judge readiness.

Read what the official MRCP Part 1 pass-rate data shows for the published figures and how to interpret them.

• Stop targeting a percentage. Target instead: no specialty far below your own average, and stable accuracy under timed conditions.
• Judge readiness on a rolling average. A 200-item exam is reliable; a 20-question block is not.
• Aim clear of the line. With a standard error around 3%, planning to scrape through is planning for a coin flip.
• Answer every question. No negative marking means a blank is strictly worse than a guess.
• Bank the finite content. Statistics, genetics, immunology and toxicology reward hours reliably — see the MRCP Part 1 syllabus breakdown.
