Choosing between MRCP and PLAB is one of the most important decisions facing any International Medical Graduate planning a career in UK medicine. This comprehensive guide breaks down all the key differences. For a full overview of MRCP itself, see our MRCP Part 1 Complete Guide 2026.
For International Medical Graduates (IMGs) aspiring to practise in the United Kingdom, the choice between MRCP (Membership of the Royal Colleges of Physicians) and PLAB (Professional and Linguistic Assessments Board) represents a critical career decision that will shape your entire professional trajectory in the NHS. Both examinations lead to General Medical Council (GMC) registration, but they differ dramatically in terms of format, cost, time commitment, difficulty, and most importantly, their impact on your long-term career prospects within the UK healthcare system.
This guide has been written by a practising NHS consultant who has experience both as an IMG and as someone who has guided numerous trainees through these examinations.
Understanding PLAB: The Foundation Route
The Professional and Linguistic Assessments Board (PLAB) test is designed specifically to ensure that doctors who qualified abroad have the necessary knowledge and skills to practise safely and effectively within the UK healthcare system at the level of a Foundation Year 2 doctor. It is the most commonly used pathway for IMGs seeking initial GMC registration.
PLAB Examination Structure
- PLAB 1: A written examination containing 180 single best answer questions. The examination is three hours long, giving you exactly one minute per question.
- PLAB 2: A practical objective structured clinical examination (OSCE) consisting of 18 stations, each lasting 10 minutes.
PLAB Costs and Timeline
- PLAB 1 fee: £283 (as of 2026)
- PLAB 2 fee: £1,036 (as of 2026)
- Total approximate cost: £1,319
Most candidates complete both parts within 3-9 months.
PLAB Pass Rates
- PLAB 1: Approximately 60-70% pass at first attempt
- PLAB 2: Approximately 70-80% pass at first attempt
Understanding MRCP: The Physician Qualification
MRCP (Membership of the Royal Colleges of Physicians) is a prestigious postgraduate qualification that demonstrates physician-level competence in internal medicine.
MRCP Examination Structure
- MRCP Part 1: Two papers of 100 single best answer questions each, sat on the same day. Total examination time: six hours.
- MRCP Part 2 Written: Two papers of 100 questions each, testing deeper clinical knowledge and diagnostic reasoning.
- MRCP PACES: Practical Assessment of Clinical Examination Skills — a five-station examination.
MRCP Costs and Timeline
- MRCP Part 1: £502 (UK) / £672 (international)
- MRCP Part 2 Written: £502 (UK) / £672 (international)
- MRCP PACES: £716 (UK) / £1,311 (international)
- Total approximate cost: £2,500-3,500 for complete qualification
Most candidates require 18-36 months to complete all three parts. For 2026 exam dates and booking deadlines, see our dedicated calendar.
MRCP Pass Rates
- MRCP Part 1: Approximately 35-45% pass at first attempt
- MRCP Part 2 Written: Approximately 45-55% pass at first attempt
- MRCP PACES: Approximately 60-70% pass at first attempt
Direct Comparison: MRCP vs PLAB
| Factor | PLAB | MRCP |
|---|---|---|
| Total Cost | £1,319 | £2,500-3,500 |

| Level of Competence | Foundation Year 2 | Physician/Specialist |
| GMC Registration Type | Full Registration | Full Registration (with full MRCP) |
| Training Access | Foundation only | ST3+ Specialty Training |
| Career Progression | Limited to Trust Grades | Direct Specialty Applications |
Which Should You Choose? Strategic Decision Framework
Can You Do Both? The Combined Approach
Many successful IMGs pursue both PLAB and MRCP during their UK career. This is perfectly acceptable and sometimes strategically advantageous.
Common Pathway: PLAB First, Then MRCP
- Complete PLAB 1 and 2 to secure GMC registration
- Secure NHS employment as a Trust Grade or Clinical Fellow
- Gain valuable UK clinical experience
- Complete MRCP Part 1 while working
- Progress to MRCP Part 2 and PACES
For practical advice on balancing MRCP study with NHS work, see our guide on working full-time while passing MRCP Part 1.
When Direct MRCP Makes More Sense
If you have clear specialty ambitions and sufficient resources, pursuing MRCP directly without PLAB can be more efficient:
- No time spent on foundation-level assessment
- Direct pathway to specialty training
- Potentially lower total cost (no PLAB fees)
- Faster progression to consultant-level practice
For details on using MRCP for GMC registration directly, see our GMC Registration with MRCP guide.
Making Your Decision: Key Considerations
1. Financial Resources
MRCP costs approximately twice as much as PLAB. If finances are a primary concern, PLAB provides a more affordable entry point to UK practice.
2. Career Ambitions
If you aspire to become a consultant in any medical specialty, MRCP is increasingly essential. Foundation-level registration via PLAB alone will limit your career progression.
3. Timeline
If you need to start earning as quickly as possible, PLAB’s 3-9 month timeline is more suitable than MRCP’s 18-36 month commitment.
4. Specialty Choice
Medical specialties virtually require MRCP for competitive entry, while some specialty areas may accept equivalent qualifications.
5. Support System
Consider whether you have access to study leave, financial support from employers, and a network of colleagues who have navigated this path before.

Frequently Asked Questions
PLAB is generally considered easier, with higher pass rates (60-70% versus 35-45%). However, “easier” does not mean “easy” — both require thorough preparation.
Yes, many candidates work in NHS positions while preparing for MRCP. However, you will need to balance clinical responsibilities with study time.
No. The full MRCP qualification (Parts 1, 2, and PACES) qualifies you for full GMC registration without PLAB.
Historically, PLAB has been more common due to its lower cost and faster timeline. However, increasing numbers of IMGs are choosing direct MRCP pathways as competition for specialty training intensifies.
