There is no fixed pass mark. The pass mark for each diet is set using a standard-setting method called borderline regression. Here's how it works:
- Each case is graded across the three domains (CP/P/F/CF), which convert to numerical scores
- Examiners also give a separate overall judgement per case: clearly above pass, borderline, or clearly below
- Statistical analysis examines the scores of candidates judged to be on the borderline
- The pass mark is derived from the score that best discriminates borderline candidates
- Total marks: 126 (from 12 cases). Typical pass mark range: 75-77
- There is no set number of stations you must pass
Pass rate data (2023-2025): Overall pass rates have ranged from 64.9% to 77.9%. First-time candidates consistently perform better, with pass rates of 69-77%. Roughly 1 in 4 first-time candidates do not pass. Every mark matters - candidates have missed passing by half a mark.
