Becoming MRCOG qualified typically takes 3 to 7 years from the point of sitting Part 1, depending on how quickly you pass each stage and how long you spend in clinical training between exams. The exact timeline depends on your exam attempt history, training intensity, and whether you are in full-time or less-than-full-time (LTFT) training.
The Three-Part Pathway: An Overview
The MRCOG is awarded by the Royal College of Obstetricians and Gynaecologists (RCOG) and requires successful completion of three sequential examinations. You cannot skip or reorder them — Part 1 must be passed before Part 2, and Part 2 before Part 3. Each part tests a progressively higher level of clinical competence, moving from basic science all the way to hands-on clinical skills.
Part 1 tests the basic and applied sciences underpinning obstetrics and gynaecology. You can sit it immediately after graduating from medical school — there is no minimum clinical experience requirement. This makes it the most accessible entry point on the MRCOG pathway.
Most candidates spend 3 to 6 months preparing, with those working full-time in clinical roles typically needing closer to 6 months. Part 1 is held twice a year, in January and July. If you need multiple attempts, each failed sitting adds a 6-month cycle before you can resit.
Part 2 assesses the application of clinical knowledge in obstetrics and gynaecology through written and extended matching question (EMQ) papers. Preparation is considerably more demanding — most candidates dedicate 6 to 12 months of focused revision, often resitting once or more before passing.
A critical rule to keep in mind: you must attempt Part 2 within 7 years of passing Part 1. For candidates in less-than-full-time training or those who take a career break, this window can be extended on a pro-rata basis, up to a maximum of 10 years. If you pass Part 1 and then delay your MRCOG journey significantly, you risk your Part 1 currency expiring.
Before you can register for Part 3, you must submit an Assessment of Training (AoT) through the RCOG. This confirms you have accumulated sufficient clinical O&G experience to sit the final clinical skills exam. The AoT is not a paper exam — it is a review of your training portfolio and documented experience.
RCOG advises allowing at least 4 weeks for AoT applications to be processed. Missing the AoT deadline for a given sitting means waiting for the next Part 3 window, which could add 6 months to your overall timeline. Plan ahead — the AoT deadline falls several weeks before the exam date itself.
MRCOG Part 3: The Final Clinical Assessment
Part 3 is an Objective Structured Clinical Examination (OSCE)-style assessment held twice a year, in May and November. Each task is 12 minutes long, and the exam tests clinical skills, attitudes, and competencies in a simulated environment. You must attempt Part 3 at least once within 7 years of passing Part 2.
Preparation for Part 3 typically takes 3 to 6 months, with heavy emphasis on communication skills, structured clinical reasoning, and role-play practice. You have 4 attempts at Part 3. If you fail all 4, you are required to resit Part 2 before trying Part 3 again.
The minimum theoretical timeline — passing all three parts on the first attempt with efficient scheduling — is approximately 2 to 3 years, but this is rare in practice. Most candidates find Part 2 the most challenging hurdle and require more than one attempt. A realistic working estimate for the full pathway is 3 to 5 years.
Scenario
Estimated Total Timeline
Key Assumption
Best-case (first-attempt passes, no delays)
~2–3 years
All parts passed first time; AoT submitted promptly
Typical pathway (one or two resits)
3–5 years
One resit at Part 2; minor scheduling gaps
Extended pathway (multiple resits or LTFT training)
5–7+ years
Multiple Part 2 attempts; career break; LTFT training
Maximum allowable window (LTFT, pro-rata extension)
Up to 10 years from Part 1
Pro-rata extension for LTFT or career breaks
Key Time Limits You Must Not Miss
The RCOG imposes strict currency rules that can catch candidates off guard. Missing these windows does not just delay you — it can invalidate previous passes entirely. Keep these deadlines fixed in your planning:
Part 1 currency: You must attempt Part 2 within 7 years of passing Part 1 (up to 10 years for LTFT/career break, pro-rata)
Part 2 currency: You must attempt Part 3 at least once within 7 years of passing Part 2
Part 3 attempts: Only 4 attempts allowed; failing all 4 requires resitting Part 2
AoT processing: Allow at least 4 weeks; missing the deadline delays you by a full 6-month cycle
Does Training Grade Affect Your Timeline?
Your stage of O&G training directly shapes your MRCOG timeline. UK trainees in the formal ST1–ST7 O&G training programme typically follow a structured schedule, with the RCOG curriculum designed so that Part 1 aligns with ST1–ST2, Part 2 with ST3–ST5, and Part 3 with ST5–ST6. However, you are not required to be in UK training to sit any part of the MRCOG — international candidates can and do sit the exams, though they must meet AoT requirements for Part 3.
International doctors working outside the UK or in non-O&G posts may find their timeline longer, simply because O&G clinical exposure is harder to accumulate quickly. The AoT process may require more planning for these candidates to ensure sufficient documented experience is in place before the Part 3 deadline.
Frequently Asked Questions
How long does it take to get the MRCOG qualification?
Most candidates complete the full MRCOG pathway in 3 to 5 years. A small number pass all three parts on first attempt and finish closer to 2 to 3 years. Those requiring multiple resits or undertaking less-than-full-time training may take 5 to 7 years or more, up to a maximum of 10 years from passing Part 1.
Can I sit MRCOG Part 1 straight after medical school?
Yes. There is no minimum clinical experience requirement for Part 1. You are eligible to sit it immediately after obtaining your primary medical qualification (e.g. MBBS or equivalent). However, most candidates find it easier to sit Part 1 after gaining at least some O&G clinical exposure.
How long is MRCOG Part 1 valid for?
Your Part 1 pass is valid for 7 years, within which you must attempt Part 2. For candidates in less-than-full-time training or those who take an approved career break, this can be extended pro-rata up to a maximum of 10 years.
What is the MRCOG Assessment of Training (AoT) and how long does it take?
The AoT is a mandatory review of your O&G clinical training portfolio that must be completed before you can register for Part 3. RCOG advises allowing at least 4 weeks for processing. You must submit your AoT application before the published deadline for each Part 3 sitting — missing it means waiting for the next exam cycle, typically 6 months later.
How many times can I attempt each MRCOG part?
Part 1 allows up to 5 attempts before additional documentation from your Head of Department is required. Part 2 allows up to 6 attempts. Part 3 allows up to 4 attempts — if you exhaust all 4, you must resit and pass Part 2 before registering for Part 3 again.
Is the MRCOG harder than other Royal College exams?
The MRCOG is widely regarded as a rigorous three-part qualification requiring sustained study over several years. Part 2 in particular has a reputation for being a significant hurdle, with many candidates needing more than one attempt. The combination of written knowledge assessment and clinical skills examination makes it one of the more comprehensive specialty training exams in the UK.
Does working part-time or taking maternity leave affect my MRCOG timeline?
Yes. Candidates in less-than-full-time (LTFT) training or those who take an approved career break are eligible for pro-rata extensions to the 7-year currency windows, up to a maximum of 10 years from passing Part 1. If you fall into this category, it is important to notify the RCOG and ensure your training records reflect your circumstances accurately.
Can international doctors outside the UK sit the MRCOG?
Yes. The MRCOG is an internationally recognised qualification and is sat by doctors worldwide. Parts 1 and 2 are available at international centres, and Part 3 is held at various overseas locations as well as in the UK. International candidates must still meet the AoT requirements for Part 3, which requires documented O&G clinical training experience.
