PLAB 1 pass mark 2026: How the GMC sets the cut-off score

The PLAB 1 pass mark 2026 is not a fixed percentage. The General Medical Council (GMC) determines the exact cut-off score for each sitting using a modified Angoff standard-setting method. Because the exam is criterion-referenced, your result depends entirely on demonstrating the required absolute knowledge, not your relative rank against other candidates.

What is the PLAB 1 pass mark?

The PLAB 1 exam does not have a static pass mark. Instead of requiring a flat 60% or 70% to pass, the GMC calculates a unique threshold for every single exam paper. This ensures fairness across different sittings, as the difficulty of questions naturally varies from one paper to the next.

GMC standard setting PLAB

The GMC uses a widely recognised psychometric process called the modified Angoff method to determine the PLAB 1 cut-off score.

Before any candidate sits the exam, a panel of experienced UK clinicians and medical educators reviews the 180 Single Best Answer (SBA) questions. For each question, the panel estimates the probability that a "borderline candidate"—a doctor who has just enough knowledge to practice safely at the Foundation Year 2 (FY2) level—would answer it correctly.

These probabilities are aggregated across the entire 180-question paper to produce a raw baseline score. Following the exam, the GMC may apply minor statistical adjustments based on actual candidate performance data to ensure the standard remains consistent with previous years. The final number becomes the absolute pass mark for that specific day.

Criterion-referenced vs norm-referenced grading

A common source of anxiety for international medical graduates is the misconception that PLAB 1 is graded on a curve. It is not.

PLAB 1 is a criterion-referenced exam. This means candidates are measured against a fixed standard of competence (the criterion). If every candidate taking the exam on a given day meets the standard, every candidate passes. If only 20% meet the standard, only 20% pass.

Candidates often confuse this with norm-referenced grading—where your score is compared to your peers, and only a set top percentage can pass. This confusion typically arises because the GMC publishes the PLAB pass percentage after each sitting, and candidates notice that the pass rate often hovers around a similar bracket. However, this consistency is a reflection of the large, statistically stable cohort sizes taking the exam, not a pre-determined quota. There is no limit to the number of doctors who can pass PLAB 1 in 2026.

Eligibility and prerequisites

Before you can book a PLAB 1 test date and worry about the pass mark, you must meet the GMC’s strict eligibility criteria.

1. Primary Medical Qualification (PMQ): You must hold a medical degree from an institution recognised by the GMC. This degree must be independently verified by the Educational Commission for Foreign Medical Graduates (ECFMG) through their EPIC service.
2. English language proficiency: You must demonstrate your ability to communicate effectively in English. The GMC accepts the International English Language Testing System (IELTS) with a minimum overall score of 7.5 (and at least 7.0 in each domain), or the Occupational English Test (OET) Medicine with a minimum grade of 'B' in all four testing areas.
3. GMC online account: You must create an account and submit your evidence. Only once your English language and PMQ evidence are accepted can you view available PLAB 1 test dates.

Structure and format of the PLAB 1 exam

To achieve the required PLAB 1 cut-off score, you must understand exactly how the exam is structured. The assessment tests your ability to apply knowledge to the care of patients, rather than your ability to recall isolated facts.

The exam is mapped directly to the UKMLA Content Map, ensuring that international medical graduates are assessed against the same clinical presentations and conditions as UK medical students taking the Medical Licensing Assessment (MLA).

Each SBA presents a clinical scenario followed by a lead-in question (e.g., "What is the most appropriate next step in management?") and five possible options. You must select the single most appropriate answer.

Study strategy: Targeting the pass mark

Because the pass mark fluctuates based on paper difficulty, aiming for a specific raw score during your preparation is a flawed strategy. Instead, your goal should be comprehensive coverage of the MLA Content Map. A standard preparation timeline spans 10 to 12 weeks.

Phase 1: Build your foundation (Weeks 1–4)

Begin by reviewing the core clinical specialties heavily tested in PLAB 1, such as acute medicine, cardiology, respiratory medicine, and general surgery. Do not rely on outdated textbooks. Base your reading on current UK clinical guidelines, specifically the National Institute for Health and Care Excellence (NICE) guidelines and the Clinical Knowledge Summaries (CKS).

Phase 2: Active recall and application (Weeks 5–8)

Transition from passive reading to active problem-solving. Use a dedicated question bank to test your knowledge. When reviewing your answers, read the explanations for both the correct and incorrect options. Understanding why a distractor is wrong is critical for the subtle clinical distinctions tested in the exam.

Phase 3: Exam simulation (Weeks 9–12)

The most significant challenge in PLAB 1 is time management. Answering 180 questions in 180 minutes requires intense concentration. Dedicate your final month to taking full-length, timed mock exams. This builds the cognitive stamina required to maintain accuracy in the final hour of the test.
