What Is Cardiothoracic Surgery ST1 Higher Specialty Training?

Cardiothoracic Surgery ST1 is the UK’s run-through training programme in cardiac and thoracic surgery, entered directly from Foundation or an equivalent post-Foundation role. Recruitment is coordinated nationally by NHS England (Wessex) via Oriel, covering posts across England, Scotland, Wales and Northern Ireland under a single person specification and scoring process.

Once appointed, you’re on the pathway all the way through to Certificate of Completion of Training (CCT) in Cardiothoracic Surgery, which puts you on the GMC Specialist Register and lets you apply for consultant posts. Training is 7 years under the 2021 curriculum; earlier cohorts trained under an 8-year framework. The first two years run alongside Core Surgical Training partners and include rotations in general surgery, vascular, ITU and cardiothoracic blocks. You’ll sit MRCS during this phase. From ST3 onwards, training is fully cardiothoracic, and you’ll declare cardiac or thoracic as your special interest by the fourth year of specialty training (i.e. ST6 in the run-through numbering, per the ISCP curriculum). The FRCS (C-Th) intercollegiate exam sits toward the end of training and is required before CCT is awarded.

The curriculum itself is set by the GMC and delivered through the Intercollegiate Surgical Curriculum Programme (ISCP), with the Joint Committee on Surgical Training (JCST) and its Cardiothoracic Surgery Specialty Advisory Committee (SAC) providing oversight. The Society for Cardiothoracic Surgery (SCTS) represents trainees professionally.

Key facts at a glance – Programme: Cardiothoracic Surgery run-through, ST1 entry – Duration: ~7 years to CCT (check the current ISCP curriculum for your intake) – End qualification: CCT in Cardiothoracic Surgery + GMC Specialist Register – Oversight: GMC, JCST/SAC, ISCP; recruitment via NHS England (Wessex) – Big change: 2026 is the final ST4 Thoracic round. From 2027, ST1 is the only entry point

Is Cardiothoracic Surgery ST1 Competitive and What Is the Lifestyle Like?

Short answer: yes, it’s one of the most competitive specialty training posts in the UK, and the lifestyle is demanding. In 2025, NHS England recorded roughly 737 applications for just 10 ST1 posts, a ratio of about 73.7:1. Around 12 posts are anticipated for August 2026, and from 2027 onwards ST1 will be the sole entry point into the specialty (2026 is the final year of separate ST4 Thoracic recruitment). If you’re weighing this up, go in with your eyes open.

Typical lifestyle. Working hours are capped at 48 per week under the European Working Time Directive, but rotas involve resident or non-resident on-calls covering nights and weekends, and trainee accounts on forums like r/doctorsUK routinely describe actual hours running higher. Your ST1 year also includes rotations through general and vascular surgery alongside cardiothoracic exposure, so early on-call patterns reflect those parent specialties too. Less-than-full-time training is available (minimum 50%), arranged via your deanery/NHS England region, and from May 2025 all resident doctors in specialty training can apply.

Career pathway. ST1 is the start of a run-through programme to CCT, typically 7 years under the 2021 curriculum, with the MRCS required before progressing out of the early years. After CCT you’ll usually sub-specialise in cardiac or thoracic surgery, with fellowship options in areas like transplantation, aortic or minimally invasive thoracic work.

Salary. ST1s sit on the national resident doctor pay scale, around £55,000–£65,000 basic in England for 2025/26, rising to roughly £76,582 at the top of training, plus London weighting (~£5,197) and enhancements for on-call and additional hours.

Cardiothoracic Surgery ST1 Eligibility Criteria and Entry Requirements

Cardiothoracic Surgery ST1 has one of the tighter eligibility gates in UK surgical recruitment, so it’s worth checking every criterion against the 2026 Person Specification published by NHS England before you apply through Oriel. The requirements below reflect the 2026 handbook; annual editions can shift wording, so confirm against the current version before you submit.

To be eligible, you’ll need to meet all of the following by the point of application:

Primary medical qualification: MBBS, BMBS or equivalent recognised by the GMC.
GMC registration: Full registration with a licence to practise by the post start date. For international medical graduates (IMGs), this typically means a recognised route such as PLAB, an approved postgraduate qualification, or GMC-recognised training.
English language proficiency: IMGs must meet GMC evidence requirements, usually IELTS Academic 7.5 overall (7.0 in each domain, single sitting) or OET (Medicine) Grade B / 350+ in each section.
Right to work in the UK: Documented at offer stage; Skilled Worker sponsorship is usually available through the employing trust.
Foundation competences: Evidence of completion of the UK Foundation Programme or equivalent foundation-level competences (e.g. CREST form for IMGs) by post commencement.
Post-graduation experience: At least 12 months’ medical experience after full registration, or equivalent, is expected under the person specification.
Prior cardiothoracic experience cap: No more than 18 months combined experience in cardiac and/or thoracic surgery (excluding foundation). Exceeding this cap makes you ineligible, a specialty-specific rule that catches people out.
Fitness to practise: Compliance with Good Medical Practice, with no unresolved concerns.

A few things you don’t need at ST1: prior Core Surgical Training is not required (this is a run-through post), and neither the MRCS nor the MSRA is an eligibility requirement at the point of application. MRCS comes later during ST1–ST2. IMGs apply through the same Oriel process on the same timeline as UK graduates; there is no separate stream.

How to Apply for Cardiothoracic Surgery ST1 National Recruitment

Cardiothoracic Surgery ST1 runs as a single annual national round coordinated by NHS England – Wessex, with all applications submitted through Oriel. Everything below is drawn from the 2026 Wessex Applicant Guide and person specification. Always cross-check the current handbook before you submit, as small wording changes appear each cycle.

Here’s the process end to end:

Confirm eligibility against the person specification. You’ll need full GMC registration with a licence to practise (or be eligible by the post start date), evidence of Foundation competences (or equivalent), and the right to work in the UK. There’s no separate entrance exam like the MSRA for CT ST1, and the MRCS is taken during training rather than before entry. If you’re still in Foundation or Core Surgical Training, check those guides for how your competences map across.
Register on Oriel and open the CT Surgery ST1 vacancy. For the 2026 cycle, the advert went live on 22 October 2025, applications opened at 10:00 on 23 October 2025 and closed at 16:00 on 20 November 2025. Expect a similar autumn window in future cycles.
Complete the Oriel form. Sections cover personal details, GMC and right-to-work information, qualifications, employment history, Foundation/equivalent competence declarations, fitness to practise, equal opportunities, and your programme preferences across England, Scotland, Wales and Northern Ireland (up to around 12 ST1 posts in 2026).
Complete the self-assessment. You score yourself against the published 2026 domains: undergraduate prizes, postgraduate degrees, publications, presentations, teaching, leadership and commitment to specialty. Every score must be backed by specific evidence (certificates, PubMed IDs, logbook entries, letters). You don’t upload evidence with the Oriel form, but you must produce it at verification.
Nominate referees in Oriel. Structured references are requested later in the process rather than at submission; the form captures contact details only.
Submit before the deadline. There’s no application fee. Late submissions aren’t accepted, and Oriel closes on the dot.
Longlisting and shortlisting. Wessex longlists to confirm eligibility, then ranks applicants on self-assessment score. The highest-scoring candidates are invited to interview (2–3 February for the 2026 round), where evidence is verified.

If you’re unsuccessful, feedback is released via Oriel once the round closes. You can reapply in the next cycle (there’s no cap on attempts), but if you’re already in a specialty training post, you’ll need a Reapplication to Specialty Training form signed by your Training Programme Director. Appeals are limited to procedural grounds or self-assessment scoring disputes, reviewed against evidence already submitted; no new evidence is accepted at appeal.

Cardiothoracic Surgery ST1 Recruitment Timeline and Key Dates (2026)

The 2026 cycle is nationally coordinated by NHS England Wessex on behalf of all four UK nations, and the standout feature is the separate evidence upload window in December, which sits between application close and shortlisting. If you’re applying, diarise that window now. It lands right across the winter holidays, so you’ll want your supporting documents ready well before 8 December.

Here’s the full timeline for August 2026 posts:

Stage	Date (2025–26)
Advert published	22 October 2025
Applications open on Oriel	10:00, 23 October 2025
Applications close	16:00, 20 November 2025
Evidence upload instructions released	by 5 December 2025
Evidence upload window opens	10:00, 8 December 2025
Evidence upload window closes	10:00, 19 December 2025
Final shortlist confirmed	Tuesday 6 January 2026
Interviews	2–3 February 2026
Initial offers released (Round 1 deadline)	by 31 March 2026
Holding deadline for offers	13:00, Thursday 2 April 2026
Offer upgrade window closes	pm, Wednesday 8 April 2026

Dates confirmed by the NHS England Wessex 2026 Applicant Guide; check the Wessex page yearly as timings shift slightly each cycle.

One extra note worth flagging: 2026 is the final year that ST4 Thoracic Surgery will be recruited separately, so from 2027 onwards, ST1 becomes the sole entry route into the specialty.

Cardiothoracic Surgery ST1 Competition Ratios and Application Trends

Cardiothoracic Surgery ST1 is currently one of the most competitive entry points in UK specialty recruitment. In the 2025 Round 1 cycle, NHS England recorded 737 applications for just 10 national posts, giving a competition ratio of 73.7:1. That’s a steep jump from 2024, when there were 408 applications for 9 posts (about 45.3:1).

Year	Applications	Posts	Ratio
2024	408	9	45.33:1
2025	737	10	73.70:1
2026 (indicative)	TBC	up to 12	TBC

Sources: NHS England competition ratios (2024, 2025); NHS England Wessex 2026 applicant guide.

The trend is unmistakably upward, and there’s a structural reason for it. 2026 is the final year of ST4 Thoracic recruitment, and from 2027 onwards, all entry into UK cardiothoracic training funnels through ST1. That’s likely to keep pressure on ST1 numbers well beyond this year. Fill rate has been 100% in recent cycles, so every post is contested to the finish.

One thing worth flagging: recruitment is a single national pool coordinated by NHS England Wessex, covering England, Scotland, Wales and Northern Ireland. You aren’t competing regionally. For 2026, up to 12 ST1 posts are indicated, with one hosted in Scotland and small allocations elsewhere, so geography is a matter of where posts sit, not where competition is softer. If MRCS timing during training is on your mind for later, our MRCS guide walks through the exam structure.

How Cardiothoracic Surgery ST1 Applications Are Scored (2026)

Cardiothoracic Surgery ST1 recruitment for 2026 is coordinated nationally by NHS England (Wessex), and it uses a formal, published scoring framework. There’s no MSRA and no separate written exam for this specialty. Instead, your ranking is built from two stages: a scored self-assessment portfolio submitted through Oriel at application, and an interview/selection centre stage for candidates who make the shortlist.

Importantly, the shortlisting score doesn’t just decide who gets to interview. The JCST confirms that for Cardiothoracic ST1, your self-assessment score also feeds forward into the total selection centre score. In other words, your portfolio keeps working for you right through to the final rank order that determines who gets first pick of programmes.

The scored domains

Based on the published self-assessment criteria, each domain uses a 0–6 scale. However, the exact weighting between domains and between the self-assessment total and interview score is not explicitly published; confirm in the current Wessex Applicant Guide before scoring yourself. At a high level, the domains include:

Domain	What it captures
Undergraduate medical career	Academic prizes, awards, honours, ranking, intercalated degrees
Postgraduate qualifications	PhD, MD (by research), Masters, PGDip, PGCert (must be medically relevant)
Publications	Weighted by authorship position and whether peer-reviewed/indexed (e.g. PubMed)
Presentations	Weighted by reach (international > national > regional > local) and format (oral > poster)
Teaching	Scope, formality, feedback, recognised teaching qualifications
Audit and quality improvement	Completed (closed-loop) cycles, leadership role, dissemination
Commitment to specialty	Taster experience, courses, engagement with cardiothoracic surgery
Leadership and management	Roles held, scope of responsibility, evidence of impact

How the domains combine

Here’s the honest bit: the official 2026 documents don’t publish explicit percentage weightings between the domains, nor a fixed ratio between total self-assessment score and total interview score. What we do know is that every domain uses the same 0–6 scale in the published criteria. Because the inter-domain weighting isn’t specified, applicants generally treat each domain as important and aim for evidence across the board rather than banking on one area to compensate for another.

With ratios like 73.7:1 reported in 2025, a single missed point can shift you a long way down the rank list. We unpack how to build evidence for each domain, and where candidates most commonly lose easy points, in the next section.

Cardiothoracic Surgery ST1 Self-Assessment and Portfolio: How to Maximise Your Score

With 737 applications chasing 10 posts in 2025, the self-assessment form is where Cardiothoracic Surgery ST1 recruitment is really won or lost. For the 2026 round, NHS England (via lead recruiter Wessex) is longlisting on self-assessment score before eligibility checks, so a strong, well-evidenced score is what gets you into the interview at all. The top-scoring applicant even gets first pick of programmes, so every point matters geographically as well as competitively.

What the 2026 self-assessment actually scores

The Wessex 2026 Self Assessment Scores and Descriptors scores discrete domains rather than general clinical experience. In recent years these have included:

Undergraduate achievements: medical school ranking (top decile evidence required), prizes and distinctions
Additional degrees: intercalated BSc, MSc, PhD, MD
Publications: PubMed-indexed papers, first-author weighting
Presentations: international, national and regional, oral vs poster
Teaching experience: delivery, evaluation and formal educator roles (holding a PGCert isn’t a separate scored line)
Quality improvement and audit: typically rewarding completed cycles, a leadership role and dissemination. Based on available evidence and the 2026 self-assessment document, exact point thresholds (e.g. how many completed cycles are needed for maximum points) should be verified in the full Wessex Self-Assessment Criteria PDF before scoring yourself.
Organisational and leadership: rota coordination, committee positions, society roles
Commitment to specialty: cardiothoracic taster days, clinical attachments and dedicated CT posts, with longer placements scoring higher

There’s no standalone logbook or operative case-count domain at ST1, and no bonus for sole applications.

How evidence is verified

Top scorers (and those within a defined margin of the cut-off) upload documentary evidence via Oriel during a tight window, 8 to 19 December 2025 for the 2026 round. Evidence must be uploaded in the same order as the form, chronologically within each domain, and in English (certified translations required otherwise). Anything unevidenced scores zero at verification, and overclaiming risks withdrawal.

Where candidates lose easy points

Do:

Get supervisor sign-off letters for QIP role, teaching delivery and attachments before December
Keep certificates, acceptance emails and prize letters filed as you go
Claim the medical school decile ranking with the correct verification letter

Don’t:

Upload evidence out of order or in the wrong domain
Claim a “publication” for something not yet accepted
Leave taster/attachment confirmation until the upload window opens

Actions to take now

If applications are still months away, book a cardiothoracic taster or attachment, close a QIP loop with a re-audit, and submit a case report or letter to an indexed journal. Solid Foundation Programme evidence and, if you’ve done it, Core Surgical Training achievements all feed directly into these domains. Dig them out early rather than reconstructing them in December.

The Cardiothoracic Surgery ST1 Interview: A Brief Overview

Once you’ve cleared self-assessment and longlisting, you’ll be invited to the national online selection interview. For 2026, it runs on 2–3 February 2026, delivered remotely via Qpercom Recruit, in two stations: a Structured Questions station (~25 min) and a Communication Skills station (~25 min).

Your self-assessment score is carried forward and combined with your interview score to determine your final ranking against Oriel post preferences.

Cardiothoracic Surgery ST1 Offers, Preferencing and What Happens Next

Once interviews are over, the offer stage runs through Oriel, the same portal you used to apply. With up to around 12 ST1 posts advertised for 2026 across England, Scotland, Northern Ireland and Wales, the allocation window can move quickly, so it helps to know the sequence before you’re in it.

Here’s how it generally works from interview to start date:

Ranking. Candidates are ranked nationally on their interview score. Successful applicants are matched to posts in ranking order against the location preferences they submitted earlier in Oriel.
Initial offer. Your first offer reflects the highest-ranked location still available when your name comes up. You’ll be notified through Oriel and given a fixed window to respond.
Hold or accept. You can Accept, Accept with Upgrades, Hold, or Decline. The hold-down period lets you wait a short time before committing while you weigh things up. Check the applicant guide for the exact hours allowed in your cycle.
Upgrades. If you opt in for upgrades, Oriel will automatically move you to a higher-preferenced post if one frees up (typically because someone above you declines). Upgrades stop at the published upgrade deadline, even if a preferred post opens later.
Pre-employment and start. Once you accept, your allocated deanery handles pre-employment checks ahead of the August start.

Remember that an ST1 offer is a run-through National Training Number, with the first two years delivered as Core Surgical Training rotations before cardiothoracic-specific training begins.

Frequently Asked Questions About Cardiothoracic Surgery ST1 Application

How competitive is Cardiothoracic Surgery ST1 in the UK?

Extremely competitive. NHS England’s 2025 Round 1 data recorded 737 applications for 10 posts, a ratio of 73.7:1, one of the highest across all UK specialties. This is up sharply from around 45:1 in 2024. With ST4 Thoracic recruitment ending after 2026, ST1 is expected to remain a significant bottleneck.

Do I need to complete Core Surgical Training before applying?

No. Cardiothoracic Surgery ST1 is a run-through entry point, so Core Surgical Training is not required. You need an MBBS or equivalent, full GMC registration with a licence to practise by the post start date, eligibility to work in the UK, and evidence of Foundation-level competences from the UK Foundation Programme or an equivalent.

Do I need to have passed the MRCS before applying to ST1?

No. The MRCS is not an essential requirement for ST1 entry; it’s a milestone you’ll complete during ST1–ST2. However, postgraduate exam progress can score under the postgraduate degrees and qualifications domain of the self-assessment, so it’s worth flagging any relevant progress on your application.

How do I apply for Cardiothoracic Surgery ST1?

Applications go through a single national process coordinated by NHS England Wessex on behalf of England, Scotland, Wales and Northern Ireland. You submit via the Oriel online portal. For the 2026 intake, applications opened on 23 October 2025 and closed on 20 November 2025, with interviews on 2 and 3 February 2026 for posts starting August 2026.

How does shortlisting work for Cardiothoracic Surgery ST1?

Applications first go through longlisting, which checks eligibility against the person specification. Shortlisting is then based on your self-assessment score against the published Wessex domain framework, covering prizes, postgraduate qualifications, research, publications, presentations, teaching, leadership and commitment to specialty. The highest-scoring applicants are invited to interview, where every claimed point must be evidenced.

How many Cardiothoracic Surgery ST1 posts are available?

Around 10 to 12 nationally. NHS England Wessex has indicated up to 12 ST1 posts for August 2026 entry, distributed across UK deaneries. Actual numbers are confirmed each cycle in the applicant guide, and the final post count typically appears on NHS England’s competition ratios page after the round closes.

Can I upgrade to a higher-preferenced post after accepting an offer?

Yes. Oriel operates an upgrade system: when you accept or hold an offer, you can opt in for upgrades. If a post ranked higher on your preference list becomes available before the upgrade deadline, Oriel automatically reallocates you and notifies you. Once the deadline passes, no further movement happens, so check the deadline in the current applicant guide.

Does a PGCert in Medical Education score extra points?

No separate points are awarded for holding a PGCert in Medical Education. The 2026 self-assessment scores teaching based on delivery, evaluation and formal roles. A PGCert can strengthen the evidence within the teaching domain, but the qualification itself does not add a scored line.
