Core Surgical Training: Entry Requirements, Application & UK Pathway
Core surgical training is the main early-stage surgical training route for doctors who plan to enter higher surgical training in the UK. Most trainees complete CT1 and CT2 over two years before applying for ST3. For the 2027 recruitment cycle, applicants need a medical degree, full GMC registration, UK work eligibility, recent foundation competence, and no more than 18 months of whole-time-equivalent surgical experience outside Foundation placements.
Core Surgical Training at a Glance
| Area | Current information |
| Training level | CT1 and CT2 |
| Typical duration | 24 months |
| Application system | Oriel |
| Main route | National selection |
| Medical registration | Full GMC registration required at application |
| Foundation competence | Must meet the current evidence requirements |
| Previous surgical experience | 18 months WTE or less for 2027 CT1 recruitment |
| Main qualification | MRCS |
| Usual next stage | ST3 specialty training |
| 2027 recruitment round | Round 1 |
| Expected 2027 post start | Normally August 2027 or later within the published Round 1 window |
The NHS Medical Hub says Round 1 advertisements for CT1 and ST1 programmes will appear in October 2026, with posts normally starting in August 2027. The exact dates and requirements can change between recruitment cycles, so applicants should use the person specification for the year in which they apply.
What Is Core Surgical Training?
Core Surgical Training develops the clinical, technical and professional skills that doctors need before entering higher surgical training. Most surgical trainees complete CT1 and CT2 before applying for an ST3 post in their chosen specialty.
The programme gives trainees experience across surgical specialties while they work through the Core Surgical Training curriculum. Trainees record their progress through the Intercollegiate Surgical Curriculum Programme (ISCP) and use their training evidence during progression reviews.
CST does not train you in one narrow surgical specialty from the beginning. It builds a broad foundation before you move into specialty-level training.
How Long Is Core Surgical Training?
Formal Core Surgical Training has an indicative duration of 24 months, normally covering CT1 and CT2. Most trainees then apply for higher surgical training at ST3.
The pathway differs for some specialties. JCST identifies Oral and Maxillofacial Surgery as the only specialty where CST can last up to 12 months without requiring at least 24 months of CST or equivalent before ST3.
Neurosurgery also follows a different route. Most neurosurgical trainees enter at ST1 and complete their core-level training within the run-through programme rather than following the usual CT1/CT2-to-ST3 route.
Core Surgical Training Entry Requirements
The 2027 CT1 person specification sets the current requirements for the next recruitment cycle. Applicants should check the official specification again before submitting an application because NHS recruitment requirements can change each year.
Medical Degree
You must hold an MBBS, BMBS or equivalent medical qualification.
The qualification must meet the requirements stated in the national person specification for the recruitment year.
GMC Registration and UK Work Eligibility
You must have full GMC registration when you apply and hold a current licence to practise when your training post starts.
You also need to meet UK work eligibility requirements and the standards set out in Good Medical Practice. The 2027 person specification also states that applicants must not already hold, or be eligible for, a Certificate of Completion of Training or specialist registration for the specialty.
Foundation Competence
For 2027 recruitment, the NHS requires evidence from one of four routes:
- Current employment in a UKFPO-affiliated Foundation Programme
- Current employment in a GMC-approved specialty training programme with an NTN or DRN
- A Foundation Programme Certificate of Completion (FPCC)
- At least 12 months of medical experience after full GMC registration, or equivalent post-licensing experience, plus a valid CREST
The NHS requires foundation competence evidence from the 3½ years before the advertised post start date.
CREST Requirements for 2027
Doctors who need a Certificate of Readiness to Enter Specialty Training (CREST) should pay close attention to the version they submit.
For 2027 recruitment, NHS England says it will accept the 2024 and 2027 versions of the CREST form. From 2028 recruitment, the 2024 version will no longer be accepted.
The NHS also requires the CREST evidence to meet specific supervision, timing, and signatory requirements. Applicants should check the official guidance before asking a consultant to complete the form.
Previous Surgical Experience Limit
For 2027 Core Surgical Training CT1 recruitment, applicants must have 18 months or less whole-time-equivalent experience in surgical specialties, excluding Foundation placements, by the advertised post start date. The NHS counts experience at any level and includes surgical work gained outside the UK.
This requirement matters particularly for international medical graduates and doctors who have already worked in surgical jobs after graduation. Calculate your previous experience carefully rather than assuming that overseas or non-training jobs fall outside the rule.
The person specification includes a specific rule for Oral and Maxillofacial Surgery applicants: only surgical experience gained after completion of both medical and dental degrees counts toward the 18-month limit.
Skills Required for Core Surgical Training
The NHS person specification looks beyond clinical knowledge. Applicants need to demonstrate teamwork, communication, organisation, decision-making and the ability to work safely under pressure.
The 2027 criteria also cover research, audit, clinical risk management, evidence-based practice, patient safety and quality improvement. Teaching, management, research and audit experience appear as desirable criteria rather than universal essential requirements.
CST has one additional essential clinical requirement: applicants must recognise an acutely ill patient and provide initial management. The specification also lists relevant extracurricular surgical activity or achievements as desirable evidence of commitment to the specialty.
How to Apply for Core Surgical Training
National surgical recruitment uses Oriel, the NHS online application system. JCST confirms that applicants for surgical national selection apply through Oriel and progress through the structured recruitment process used for the relevant specialty.
For the 2027 cycle, Core Surgical Training falls within Round 1. NHS England currently says Round 1 advertisements will appear in October 2026 and that CT1/ST1 posts normally start in August 2027.
Before applying, check the relevant person specification, confirm your GMC status, calculate your surgical experience,ce and prepare any foundation competence evidence that you need to upload.
2026 CST Recruitment Process
The 2026 recruitment cycle provides useful context for applicants preparing for the next cycle, but you should not assume that every 2026 rule will remain unchanged for 2027.
For 2026, all longlisted CST applicants took the Multi-Specialty Recruitment Assessment (MSRA). NHS England then invited the highest-scoring 1,200 applicants to interview and upload evidence.
The 2026 selection score combined three components:
| Selection component | 2026 weighting |
| MSRA | 10% |
| Portfolio station | 45% |
| Management and clinical station | 45% |
| Total | 100% |
NHS England published these weightings specifically for the 2026 recruitment process. Applicants for 2027 should use the final 2027 recruitment guidance rather than treating these figures as confirmed for the new cycle.
What Is the MSRA?
The Multi-Specialty Recruitment Assessment (MSRA) is a computer-based assessment used in several UK medical recruitment processes.
For 2026 CST recruitment, NHS England required all longlisted candidates to take the MSRA as part of the selection process. The assessment therefore played a shortlisting role before the interview stage.
If NHS England retains the MSRA for the 2027 CST process, the final recruitment guidance will set out the exact assessment arrangements. Candidates should use the current official recruitment information rather than relying on preparation advice from an earlier cycle.
CST Portfolio Requirements
Portfolio evidence supports the assessment of your experience outside routine clinical work. Relevant evidence can include surgical experience, teaching, research, audit, quality improvement, presentations and other achievements that match the published criteria.
The portfolio requirements changed for the 2026 recruitment process. NHS England removed foundation placements as an accepted example of surgical experience and stated that QI or audit evidence should show presentation of the project in the area where it aimed to create change.
For the 2027 process, NHS England says the evidence domains are likely to align with the domains in Good Medical Practice. The recruitment guidance also requires candidates to provide an index page explaining where their evidence fits within the relevant domains.
Keep your evidence organised throughout the year rather than trying to reconstruct your portfolio shortly before the upload deadline.
How the CST Interview Worked in 2026
The 2026 process used a multi-station interview structure that included a portfolio station.
Candidates received a 10-minute period during which interviewers reviewed the portfolio evidence. They then completed a 15-minute virtual portfolio interview, with five minutes allocated to each question across two portfolio domains.
The wider interview process also included management and clinical assessment. NHS England combined those interview scores with the MSRA score to produce the final selection score for 2026.
The 2027 recruitment information should confirm whether NHS England retains this exact structure.
What Should You Include in a CST Portfolio?
Build your portfolio around evidence that matches the published recruitment criteria. A certificate has value when it demonstrates an achievement relevant to the selection framework, not simply because it adds another document to your application.
Useful areas include:
- Audit and quality improvement
- Research
- Publications
- Presentations
- Teaching
- Surgical experience
- Leadership and management
- Relevant courses
- Professional development
- Surgical extracurricular activities
For QI and audit, keep evidence of the project, your role, presentation, and the change you intended to achieve. NHS England specifically highlighted the importance of demonstrating the presentation of QI or audit work in the area where the project aimed to produce change.
ISCP and Progress During CST
The Intercollegiate Surgical Curriculum Programme (ISCP) plays an important role during training.
JCST expects trainees to use ISCP to record their progress and follow the Core Surgical Training curriculum. You should keep the record updated throughout training because JCST states that activity not recorded on ISCP may not count toward your Annual Review of Competence Progression (ARCP).
This makes regular portfolio and ISCP updates part of your training routine rather than an administrative task to complete at the end of CT2.
MRCS During Core Surgical Training
The Membership of the Royal Colleges of Surgeons (MRCS) examination forms part of the formal CST pathway.
JCST states that MRCS is an exit requirement for formal Core Surgical Training. You must obtain the qualification before completing formal CST and starting an ST3 post.
That requirement makes exam planning important from the start of CT1. Your exact preparation schedule will depend on your training programme, previous knowledge and the requirements of your intended specialty.
What Happens After Core Surgical Training?
Most surgical trainees move from CT1 and CT2 into specialty-level recruitment at ST3. JCST states that most surgical specialties recruit at ST3 after trainees complete Core Surgical Training.
Your next application will focus more closely on the specialty you want to pursue. JCST recommends that trainees understand the ST3 person specification for their intended specialty while they are still completing CST.
This allows you to identify specialty-specific requirements early and build relevant evidence during CT1 and CT2.
Surgical Specialties After CST
CST provides broad surgical training before specialty-level progression. Depending on the specialty and recruitment structure, doctors can progress toward areas such as:
- General Surgery
- Trauma and Orthopaedic Surgery
- Urology
- Vascular Surgery
- Cardiothoracic Surgery
- Plastic Surgery
- ENT
- Other recognised surgical specialties
Not every specialty follows the same recruitment route. Neurosurgery mainly uses run-through training from ST1, while Cardiothoracic Surgery and OMFS also have run-through options alongside ST3 recruitment.
Check the person specification for the specialty you want to enter because its requirements may differ from those of another surgical specialty.
Core Surgical Training for International Medical Graduates
International medical graduates can apply for CST if they satisfy the requirements for the relevant recruitment year.
For the 2027 CT1 cycle, an IMG must hold full GMC registration at application, have a current licence to practise when the post starts, meet UK work eligibility requirements and provide acceptable evidence of foundation competence.
The previous-experience rule deserves particular attention. Surgical experience gained outside the UK counts toward the 18-month whole-time-equivalent limit, so overseas surgical jobs need to form part of your eligibility calculation.
If you need a CREST, check the current NHS guidance carefully before submitting the application. For 2027 recruitment, NHS England will accept the 2024 or 2027 CREST versions.
England, Scotland and Wales
Core Surgical Training recruitment covers England, Scotland and Wales through the national recruitment framework, although individual training arrangements can differ.
The 2026 cycle illustrates this difference. England paused recruitment to all Improving Surgical Training posts for 2026 and added those posts back into core surgical recruitment, while Scotland and Wales continued to recruit to run-through IST arrangements.
Applicants should therefore examine the actual programme details attached to their Oriel preferences instead of assuming that every region offers the same structure.
2027 Core Surgical Training Recruitment
The 2027 recruitment cycle is the relevant upcoming cycle in September 2026.
NHS England currently places CT1/ST1 recruitment in Round 1, with advertisements scheduled for October 2026. Posts recruited through Round 1 will normally start in August 2027 and generally no later than December 2027, although the national guidance allows later starts for specialties with particular recruitment arrangements.
The NHS also states that applicants must check the person specification for the specific recruitment year because requirements can differ from one cycle to another.
For that reason, do not copy dates, scoring systems or portfolio rules from the 2026 CST cycle into a 2027 application without checking the updated official guidance.
What to Prepare Before Applying
Start with eligibility rather than portfolio points. Confirm your GMC registration, UK work eligibility, foundation competence evidence and previous surgical experience before spending significant time on application preparation.
Then organise evidence for audit, QI, research, teaching, presentations and surgical experience. Keep documents in a clear folder and maintain your ISCP record once you enter training.
Finally, read the person specification for the specialty you eventually want to enter at ST3. JCST specifically recommends this approach because the requirements for higher specialty training can influence the experience and evidence you should build during CST.
