The GMC Online application opens a 24-month window from the moment you pay the £1,974 fee. Within that window, you upload evidence mapped to your SSG domains, appoint referees who complete structured reports through the system, and then submit. Processing after submission typically takes 6 to 18 months. Do not open the application until a substantial portion of your evidence is already compiled.
What GMC Online does - and what it does not
GMC Online is the GMC's applicant portal at gmc-uk.org. For Portfolio Pathway candidates it handles the administrative spine of the application: opening the case, managing the 24-month window, accepting uploaded evidence, sending referee invitations, and taking the final submission. It is not a portfolio builder, a gap analysis tool, or an evidence adviser. It does not tell you whether your evidence is sufficient before you submit, and it does not prioritise or expedite applications.
Understanding what the system actually does - and does not do - matters because a surprisingly common mistake is treating GMC Online as the place where the application "happens". The application happens in your clinical work, your audit cycles, your reflective practice and your relationships with referees. GMC Online is the envelope. Everything in this guide is about filling that envelope correctly, not about what goes in it.
For the underlying substance of what evidence you need, the authoritative source is your Specialty Specific Guidance (SSG). For the overall framework your evidence maps to, read the four GMC domains article first. For the Capabilities in Practice framework, see the CiPs guide. This article assumes you have already done that reading and are now focused on the mechanics of the actual submission.
GMC Online allows only one active Portfolio Pathway application at a time, in one specialty. You cannot run parallel applications in two specialties. Choose your specialty before you open the application - you cannot change it afterwards without withdrawing and starting again.
Before you open the application: what to have ready
Opening the application starts the 24-month clock. That is the most important single fact in this article. Everything that follows from it: do not open the application until you are confident you can compile and submit a complete portfolio within 24 months. That sounds obvious. In practice, many candidates open the application too early, spend 20 months building their evidence, and then find themselves scrambling through the final months trying to plug gaps they only discovered late.
The preparation that should happen before you log in and click "Apply" falls into five areas.
1. Read your SSG cover to cover
Your Specialty Specific Guidance tells you exactly what the Royal College expects to see and in what form. Read the version currently published by the GMC. The SSG defines the required evidence across the four domains, gives indicative numbers for case logs and assessments, and sets out what structured reports must address. Everything you upload in GMC Online should map back to this document.
2. Confirm your specialty
The specialty you select when opening the application is fixed. If you are a Geriatrician who also does General Internal Medicine work, read both the Geriatric Medicine and GIM overview guides and decide before you open. For dual-accreditation questions, your SSG and the relevant Royal College guidance are the primary sources.
3. Understand the fee
The statutory fee is paid when the application opens, not when you submit. The costs article covers fees in full; the GMC statutory instrument sets the actual figure. In 2026 it was £1,974 - confirm the current amount at the GMC fees page before applying, as fees are reviewed annually. The fee is non-refundable once the window opens.
4. Brief your referees before you add them
Referee availability is the most common single cause of delayed submissions. GMC Online sends referees an automated invitation via email, but referees who have not been briefed often do not know what is expected of them or how long it will take. Speak to each intended referee before you open the application. Confirm they are willing, available within your intended timeline, and understand that they will be completing a structured report through a GMC portal - not just writing a letter.
The structured reports and referees guide covers what referees must address. Brief them against it. A referee who is not clear on the SSG requirements for your specialty may write a report that does not cover what the panel needs to see - a harder problem to fix than a delayed submission.
5. Have a substantial proportion of your evidence ready
A good rule of thumb: before you open the application, have at least 60 to 70 per cent of your evidence compiled and a credible plan for the rest within the next 12 to 18 months. If you are starting a multi-source feedback cycle, a significant audit project, or a round of workplace-based assessments from scratch, open the application only once those are underway.
SSG read and evidence mapped against it. Specialty confirmed. Referees briefed and available. At least 60 per cent of evidence compiled. Fee amount confirmed. CV and structured CV in current format. Then open the application.
Opening the application: the 24-month window begins
Log into GMC Online at gmc-uk.org with your existing GMC credentials. Every doctor holding GMC registration already has an account - you do not need to create one. Navigate to "Apply for Specialist Registration" and select the Portfolio Pathway route. You will be asked to select your specialty from a list matching the GMC's approved specialties for this route.
The payment screen comes before the application is formally opened. Pay the statutory fee by debit or credit card. Once payment completes, your application is live and the 24-month window has started. Note the date. Mark it in your calendar with 18-month and 22-month alerts.
The application immediately becomes accessible in your GMC Online dashboard. You will see a reference number, your specialty, and the current status. Keep a note of the reference number - you will need it for any correspondence with the GMC.
The form, section by section
The GMC Online Portfolio Pathway application is divided into five main sections. Each must be complete before you can submit. Here is what each section asks for and the practical points that catch candidates out.
Illustrative mockup. The actual GMC Online interface may differ.
Personal details
Pre-populated from your existing GMC registration. Check your GMC-registered address and ensure your name matches your qualifications exactly. Discrepancies between your passport name and your GMC registration name are a common source of administrative delays. Update your GMC registration details before opening the application if there is any mismatch.
Qualifications and employment history
You will need to declare your primary medical qualification and your employment history in medicine. This section verifies your route into practice and establishes the professional context for your evidence. For doctors who trained overseas, your employment history provides the backdrop against which the Royal College reads your case logs and assessments. Be thorough - unexplained gaps in employment history require explanation later.
Evidence upload
The largest and most time-intensive section. You upload each piece of evidence as a separate document, assign it to one or more GMC domains, and tag it against the relevant Capability in Practice from your SSG. Each document must be a PDF. Most applicants submit between 60 and 120 individual documents. Organise your files before you start uploading - a clear, consistent filename convention saves considerable time when you need to amend or cross-reference later.
Referee management
Add your referees through the Referees section. GMC Online sends each referee an automated invitation to a separate referee portal where they complete a structured report. Referees do not see your uploaded evidence - they complete their assessment independently. You can see their submission status in your dashboard. All required referees must have submitted before you can progress to final review.
Declaration and review
A summary page showing all sections, referee statuses and your declaration of accuracy and honesty. Review everything carefully before submitting. Once submitted, you cannot add, remove or amend documents. This is the point at which the 24-month window effectively ends for evidence purposes, even though the clock does not stop running.
Uploading and mapping your evidence
Evidence upload is where most of the practical work in GMC Online sits. The mechanics are straightforward: PDF, upload, tag. The complexity is in the tagging, and in having a systematic approach before you start rather than working it out document by document inside the form.
Build your domain map first
Before you upload a single document, build a spreadsheet or table listing every piece of evidence you plan to include, the domain or domains it maps to, and the specific SSG item it addresses. This serves two purposes: it forces you to audit your evidence against your SSG before it goes in the form, and it gives you a cross-reference table if you need to explain your mapping to the GMC or Royal College later.
The four GMC domains - Knowledge, Skills and Development; Patients, Partnership and Communication; Colleagues, Culture and Safety; and Trust and Professionalism - are the top-level categories. Within each, your SSG specifies the Capabilities in Practice (CiPs) you need to demonstrate. Mapping is not one-to-one: a single audit project with a completed cycle, a reflection, and documented change typically maps to Domain 1 (quality improvement), Domain 3 (patient safety, audit culture), and can support Domain 2 if it involved patient-facing improvement. Most assessors find evidence that explicitly acknowledges its cross-domain relevance easier to assess than evidence tagged to a single domain.
Knowledge, Skills and Development
Case logs, WBAs, audit, QI, CPD records, research, specialty-specific clinical evidence. The technical core of your practice.
Patients, Partnership and Communication
Patient feedback, consent documentation, communication-related reflections, clinic letters showing complex decision-making.
Colleagues, Culture and Safety
MSF, significant event analysis, team-level quality work, leadership evidence, safeguarding and duty of candour records.
Trust and Professionalism
Appraisals and PDPs, probity declarations, complaints handling, conflicts of interest, teaching and supervisory roles.
File format and size
GMC Online accepts PDFs only. Maximum file size per document is typically 25 MB. Convert Word documents, Excel logs and web-based evidence to PDF before uploading. If your hospital e-portfolio or appraisal system exports in a proprietary format, export to PDF at source rather than printing and scanning - the quality and file size will be substantially better.
Name your files consistently before uploading. A convention such as [DOMAIN]-[EVIDENCETYPE]-[DATE]-[DESCRIPTION].pdf - for example D1-AUDIT-2025-Sepsis-QI-Project.pdf - makes the upload list easier to review and helps the Royal College assessors find what they are looking for. Random filenames like "scan001.pdf" create unnecessary friction for everyone.
Evidence that requires particular attention
Certain evidence types need specific handling before they go into the system. Reflective writing should be patient-anonymised before upload - GMC Online does not anonymise documents automatically. Case logs from clinical systems may need reformatting into a table or narrative that makes the clinical complexity visible; raw electronic system exports rarely give assessors the context they need. MSF reports typically export from the MSF platform as a PDF already; include the summary report and the completed reflection together in a single document rather than as two separate uploads.
For workplace-based assessments, include both the completed assessment form and your written reflection on it. An assessment without a reflection adds limited value. An assessment with a reflection that demonstrates insight, changed practice and measurable outcome is the evidence that assessors weight.
| Evidence type | Format in GMC Online | Required | Common issue |
|---|---|---|---|
| Case logs / clinical activity | PDF table with dates, case type, complexity, role | Required | Raw system exports lack clinical context |
| Audit and QI | One PDF per project: protocol, results, action plan, re-audit | Required | Loop not closed; reflection missing |
| MSF | MSF platform export + reflection in one PDF | Required | Reflection generic; no response to specific themes |
| WBAs (mini-CEX, CbD, DOPS) | Assessment form + reflection together | Required | Forms uploaded without reflections |
| Patient feedback | Validated tool results + patient survey data + reflection | Required | Informal feedback without validated tool |
| Teaching logs | Log of teaching activities, roles, evaluation data where available | Optional | Activity logged without evidence of impact |
| Publications and research | Published paper PDF + ICMJE authorship statement if applicable | Supporting | Preprints or conference abstracts presented as full papers |
| CPD records | Annual CPD log + appraisal record linking CPD to PDP goals | Required | Activities listed without reflection or relevance mapped to specialty |
| Significant event analysis | Written SEA using seven-stage structure, anonymised | Supporting | Summary too brief; no system analysis or change evidence |
| Annual appraisals and PDPs | Three to five years of completed appraisals with PDP sign-off | Required | PDPs generic; no link to specialty development goals |
Managing referees through GMC Online
Referee management is the section of GMC Online that most candidates underestimate. It is also the most common single point of failure for applications that stall before submission.
How the referee system works
Once you add a referee's details to your application, GMC Online sends them an automated email with a unique link to a referee portal. Referees log in separately (they do not need an existing GMC account, though existing GMC registrants use their own login), and they complete a structured report through that portal. The report asks them to comment on specific aspects of your practice, mapped to the four domains of Good Medical Practice.
Your dashboard shows each referee's status: invited, in progress, or submitted. You cannot see the content of their report - only whether it has been received. The GMC does not share structured reports with candidates before a decision is made.
Number and type of referees
The number and type of referees required varies by specialty. Your SSG is the definitive source. Most specialties require at least two structured reports, typically including a current educational supervisor or equivalent, and at least one other senior clinical colleague who has observed your practice at Consultant level. Some specialties require more, or specify roles more precisely. Read the structured reports and referees guide for the full detail on choosing, briefing and managing referees.
GMC Online will not allow you to submit your application until all required referees have completed their reports. A referee who goes on extended leave, changes jobs, or simply does not respond can hold your entire submission hostage, potentially beyond your 24-month window. Add referees early. Chase politely but consistently. Have a contingency referee identified in case your primary choice becomes unavailable.
Briefing referees properly
When you add a referee to GMC Online, include in your covering note to them: your specialty, the SSG domains you expect them to cover, the indicative length of the structured report, the deadline you need them to submit by (allow at least four weeks before your intended submission date), and a brief summary of the evidence you have submitted so their report complements rather than duplicates it. A referee who knows what the panel needs to read writes a substantively better report than one who receives an automated system email with no context.
Referees and overseas-trained doctors
For doctors who trained overseas and are now working in the UK, referees must be UK-based clinicians who have observed your practice in the UK NHS context. Overseas referees who know you well but have not seen you work in NHS settings are of limited value to a Royal College assessor who is specifically evaluating your suitability for UK specialist practice. Build referee relationships within your current UK post. This is one more reason why, for most internationally-trained doctors, taking a UK post first rather than applying directly from overseas is the more reliable route.
The final review and submission
When your evidence uploads are complete and all required referees have submitted, GMC Online makes the Review and Submit page accessible. Work through this page systematically before clicking submit.
Check that every evidence item is correctly tagged to the right domain and CiP. Review the referee list - names, specialties and statuses - against what your SSG requires. Read your personal statement one final time. The declaration at the bottom confirms that the information you have provided is accurate and complete. By submitting, you are also confirming that the evidence is your own work and that you have not misrepresented your clinical activity, qualifications, or relationships with referees.
Once you submit, GMC Online locks the application. You cannot add, remove, or amend documents. If the GMC or Royal College subsequently identifies a gap in your evidence, you will be contacted with a request for additional information - but that process is on their timeline, not yours, and it extends the overall assessment period. Submit a complete application rather than a quick one.
Withdrawing an application
You can withdraw an application at any point before submission through GMC Online. If you withdraw, the application closes and the fee is not refunded. There is no partial refund for unused months. If you discover a significant evidence gap after opening the application, the better approach is usually to use the remaining window to plug the gap rather than withdraw and restart - provided you have enough time left to build the missing evidence.
After you submit: what happens next
Submission is not the end. It is the start of a separate assessment process that you do not control. The article on what happens after submission covers the full sequence; here is the short version.
The GMC carries out an administrative review to confirm the application is complete and that all required documents are present. This typically takes several weeks. The GMC does not evaluate the quality of your evidence at this stage - only its presence. If something is missing, they will contact you with a request. Once the administrative review passes, the application is forwarded to the relevant Royal College or Faculty.
The Royal College convenes an assessment panel for your specialty. The panel reads your portfolio and makes one of three decisions: approve, defer (request additional evidence), or decline. Processing times vary by specialty and the current volume of applications. Across specialties, most candidates wait between 6 and 18 months from submission to a panel decision. Some specialties are faster; a few are currently slower. The GMC publishes indicative processing times on its website.
You will be notified of the outcome by letter (via GMC Online). If approved, your name is added to the GMC Specialist Register, typically within a few weeks of the decision. At that point you are legally eligible for a substantive NHS Consultant post in your specialty.
Common GMC Online problems and how to avoid them
The problems that stall Portfolio Pathway applications in GMC Online tend to cluster around a handful of predictable issues. Most are avoidable with preparation.
The 24-month window running out
This is the most serious and the most preventable. Applications that lapse because the window expires are dead: the fee is lost and a new application is required. The cause is almost always opening the application before a realistic completion plan is in place. Read the 24-month window strategy article before you open your application. Mark your window closure date prominently and work backwards from it with specific evidence milestones.
Missing or delayed referees
Covered above, but worth repeating: brief referees before you add them to the system, give them a clear deadline at least four weeks before your intended submission, and identify a contingency referee in case one becomes unavailable. Some candidates have their applications held up for months by a single referee who has changed jobs or gone on extended sick leave. You cannot substitute a referee after submission - build flexibility into your referee plan before the window closes.
Evidence in the wrong format or exceeding size limits
GMC Online has strict format requirements. Non-PDF uploads are rejected. Files over the size limit cannot be uploaded. Convert all documents to PDF at source before you start uploading - do not leave format conversion to the day you are trying to submit. If a clinical log from your hospital system exports as Excel or Word, convert it to PDF immediately and keep both versions so you can re-export cleanly if needed.
Domain mapping inconsistencies
Evidence tagged to the wrong domain or to an irrelevant CiP creates confusion for assessors and can raise questions about whether you understand the framework. Build your domain map before uploading (as described above) and review it before submission. If you are unsure how a particular piece of evidence maps, your SSG and the four domains guide are the reference points.
Submitting an incomplete application under time pressure
The 24-month deadline creates real pressure in the final weeks. Candidates who are running late sometimes submit an incomplete application hoping to add evidence through the additional information process after the panel flags it. This is a poor strategy. The assessment panel is making a judgement on completeness; a portfolio that is obviously incomplete at submission signals that the candidate is not ready, regardless of what later information might be provided. Submit when you are genuinely ready, not when you are running out of time.
For doctors applying directly from outside the UK, the GMC Online process is the same, but the substance of what you upload faces a more difficult assessment. Royal College panels expect evidence that reflects NHS clinical practice closely. Evidence from healthcare systems structured differently to the NHS can be technically complete but substantively unconvincing. The Portfolio Pathway overview is honest about this: for most internationally-trained doctors, the stronger route is to work in a UK post first and build evidence from inside the NHS before submitting.
Your specialism overview guides
The evidence you upload and the way you map it to domains will differ by specialty. Each specialism guide below covers the specific SSG, the indicative numbers, the evidence the Royal College weights most heavily, and the common points where applications in that specialty stall.
