The GPhC Common Registration Assessment pass rate data tells a clear story: this exam is harder than most trainees expect, and the failure rate is not improving consistently. Understanding the data — not just the headline numbers, but what they mean for your preparation — is the first step toward being on the right side of the pass/fail line.
Pass Rate Data by Sitting
| Sitting | Part 1 Pass Rate | Part 1 Pass Mark | Part 2 Pass Rate | Part 2 Pass Mark | Overall Pass Rate | Candidates | Source |
|---|---|---|---|---|---|---|---|
| June 2025 | 84% | 24/40 | 86% | 79/120 | 77% | 2,913 | GPhC announcement / Board of Assessors feedback |
| November 2024 | ~58% (estimated) | TBC | TBC | TBC | ~58% | TBC | GPhC data |
November 2024 overall pass rate of approximately 58% (42% failure rate) is widely cited in the trainee community. Exact per-part breakdown should be verified from the official Board of Assessors feedback document for that sitting before publication.
Additional sittings (November 2025, June 2026) will be added as data becomes available.
What the Data Tells Us
The failure rate is not stable. The swing between 42% failure in November 2024 and 23% failure in June 2025 is substantial. This reflects both cohort differences (November sittings historically have higher failure rates than June sittings — candidates who were not ready for June often defer to November, creating a cohort with a higher proportion of underprepared or resitting candidates) and paper difficulty variation (pass marks are set by Angoff methodology and vary by sitting).
Part 1 is the predictable failure point. In June 2025, 16% of candidates failed Part 1 alone. Their Part 2 performance — however good — was irrelevant. Part 1 is the most drillable, most predictable section of the exam, and yet it eliminates roughly 1 in 6 candidates every sitting.
Part 2 law and governance is the consistent underperformance area. The Board of Assessors flags law and governance questions as a persistent weak point across sittings. Candidates know therapeutics from MPharm training. Law requires specific UK legislative knowledge that daily practice does not reinforce.
The 3-attempt limit makes every sitting high-stakes. With a maximum of 3 lifetime attempts, a 42% failure rate in any single sitting means a significant proportion of candidates will use multiple attempts — and some will exhaust all three. The candidates who pass first time are overwhelmingly those who prepare using targeted, adaptive resources rather than passive reading or static question rotation.
What Failing Candidates Consistently Get Wrong
From Board of Assessors feedback across multiple sittings:
Part 1: Displacement values (candidates ignore displacement volume), rounding errors (rounding at the wrong stage of multi-step calculations), IV infusion rate unit mismatches (mcg vs mg), and time pressure (running out of time on later questions because earlier questions took too long).
Part 2: CD prescription validity (missing required elements), emergency supply provisions (confusing patient-request and prescriber-request rules), prescribing in renal impairment (not adjusting doses for CrCl), paediatric dosing errors (not checking against BNFc maximum doses), and drug interaction management (knowing an interaction exists but not knowing the clinical management — adjust dose, monitor, or avoid).
How Adaptive Practice Addresses the Pattern
The failure pattern is consistent — the same topics appear in feedback across sittings. This means the failure is predictable. And predictable failure is addressable through targeted, adaptive practice.
iatroX tracks your proficiency across every CRA content area — every therapeutic domain, every calculation type, every law topic — and concentrates practice on your weakest areas. If your displacement value calculations are consistently slow, the engine drills displacement until your speed improves. If your CD prescription validity knowledge has gaps, the engine serves more law scenarios until the gaps close.
The performance dashboard shows you exactly where your exam risk lies — before the sitting, not after. This is the intervention the pass rate data demands: not more questions, but smarter questions that target the specific areas where candidates fail.
