Scoring, Pass Marks & Borderline Regression
- Each case is graded across the three domains (Clear Pass / Pass / Fail / Clear Fail), which convert to numerical scores. The Clinical Management and Medical Complexity domain is weighted slightly higher than the other two, though domain weighting can vary between cases
- In addition to the three domain grades, examiners provide a separate overall global judgement for each case, rating overall performance on a scale from Clear Pass through to Fail
- The pass mark is not fixed. It is set individually for each diet using a standard-setting method called borderline regression — an established approach in medical OSCE-type exams. Statistical analysis examines the domain scores of candidates judged to be on the borderline, and derives a pass mark that fairly discriminates between those meeting the standard and those who do not
- Total marks available: 126 (from 12 cases). The RCGP does not publish the exact pass mark for each diet, but third-party analysis suggests it typically falls in the range of 75–80 marks
- There is no set number of stations you must pass — your overall total across all 12 cases determines your result. Strong performance in some cases can compensate for weaker performance in others
Pass Rate Data (November 2023 – September 2025)
Across all diets since the SCA launched, overall pass rates have ranged from 64.9% (January 2025) to 77.9% (May 2024). First-time candidates consistently outperform resitters, with first-attempt pass rates typically between 69% and 77%.
To put this in perspective: roughly 1 in 4 first-time candidates do not pass, and in some diets the figure is closer to 1 in 3. Every mark matters — scores are calculated to half-mark precision, and the difference between passing and failing can be extremely narrow. This is why thorough preparation is not optional.
| ⭐ KEY POINT: You do not need to be perfect. You do not need to pass every station. But you do need to demonstrate a consistent, safe, patient-centred standard across all 12 cases. The candidates who pass comfortably are the ones who perform solidly everywhere, not the ones who are brilliant in three cases and fall apart in three others. |
