A 2027 training number is one route into a UK medical career. Missing one does not end the UK options.
A numbered programme gives you a defined curriculum and a route to CCT. The alternatives offer less structure, and some can still lead to the Specialist Register. Judge them by the work, supervision and outcome they offer, not by the job title.
We won't repeat the priority groups here. They are set out in our guide to the Medical Training (Prioritisation) Act, including the parts of the 2027 rules that were still unresolved on this page's update date.
What to look for in an NHS service post
Trust grade, trust doctor, locally employed doctor and clinical fellow are local job titles. NHS Employers confirms that trusts use several titles for locally employed doctors, without one national convention. One clinical fellow post may include protected teaching and useful specialty exposure. Another may be mostly rota cover.
Read the job description as carefully as a training person specification. Ask who will supervise you, whether you will have an appraisal, what study leave is written into the contract, and whether the department will support workplace assessments. If a post advertises theatre, clinic or procedure time, ask how that time is protected when the rota is short. Get the answers before you move.
A service post can be a sensible next job even when it does not imitate training. It can provide recent NHS references and enough exposure to decide whether you like the specialty. It also pays a salary while you decide what comes next.
SAS work is a different proposition. Specialty doctor and specialist posts are established career grades outside formal postgraduate training, with their own contracts and person specifications. They suit doctors who have enough postgraduate and specialty experience to work at that level. For some, SAS is a destination with clinical, teaching and leadership work. For others, it is the employment base from which they build a Portfolio Pathway application. Don't apply to a post merely because it contains the word "specialty". Check the duties, entry criteria, pay scale and development time.
NHS service may matter directly if the coming regulations recognise it as "significant NHS experience". Early autumn 2026 was the government's timetable, but no regulations had appeared by this page's update date. The threshold was undecided, as was whether trust-grade and other locally employed doctor time would count. The BMA is lobbying for five years of NHS or HSC experience, but that is its policy position, not the rule.
Treat any future priority benefit as possible upside. A poor post does not become a good one because a rule might help later. Under the published 2026 arrangements, trust-based programmes and non-training posts that lead to an Alternative Certificate of Eligibility were excluded from the qualifying-programme route. Watch NHS England's live prioritisation page for the regulation itself. A recruiter, WhatsApp group or course provider can't promise that your service time will qualify.
A LAT post is temporary, but it is training
As NHS England explains, a Locum Appointment for Training fills a temporary gap in a training programme. The post covers a defined piece of training without carrying a National Training Number for the whole programme or promising a CCT. LAT posts advertised through national recruitment are applied for on Oriel and remain competitive.
Its importance for an IMG is quite specific. In the 2026 rules, completion of or current enrolment in a LAT in the same specialty was a qualifying programme route for relevant ST3 or ST4 applications. A LAT in another specialty did not confer that status. The training route has to be an accepted entry route for the higher specialty in its person specification.
If you see a LAT you would take on its own merits, read the advert closely. Confirm the recognised training level, educational supervision, likely length and what evidence you will receive at the end. Then check the current priority wording for the higher-entry application you have in mind. The post and its relevance carry the value. The three letters alone carry very little.
MTI is no longer open to new applicants
The Medical Training Initiative used to offer overseas doctors a time-limited NHS training placement on an "earn, learn and return" basis. It still appears on plenty of career-option lists, but the Academy of Medical Royal Colleges closed the scheme to new applicants at noon on 31 March 2026. Existing participants can complete their placements; there is no confirmed replacement.
If you are already on MTI, your placement remains what you agreed: temporary training and development, with a maximum stay of two years under that scheme, followed by return to your home country. If you are considering the UK from abroad in 2027, remove MTI from your new-application shortlist unless an official successor is announced.
The Portfolio Pathway can lead to the Specialist Register
The route many doctors still call CESR is now described by the GMC as the Portfolio Pathway. It is for a doctor who hasn't completed a GMC-approved training programme but can show the knowledge, skills and experience required of an eligible UK specialist. A successful application leads to entry on the Specialist Register without a CCT or a National Training Number.
Years served in non-training posts do not satisfy the Portfolio Pathway by themselves. The GMC assesses a Portfolio Pathway application from documentary evidence against the relevant specialty requirements. A large volume of evidence from one familiar part of the curriculum cannot quietly cover a gap elsewhere. You need to know which capabilities your present job lets you demonstrate and where the gaps remain.
That changes how you should choose service work. Before accepting a long contract, open the current GMC specialty-specific guidance and compare it with the post. Can the department give you the breadth of clinical exposure you lack? Will supervisors observe and document your work? Are there realistic opportunities for quality improvement, teaching and management evidence? If a gap needs a rotation or a session in another department, discuss it early and get a named person to help arrange it.
The Portfolio Pathway is usually a years-long career plan built through prospective evidence collection. It can be a very good plan, provided your employer supports it from the beginning. Keep anonymised, verified evidence as the GMC requires, and review your map against the live specialty guidance because curricula change.
Sitting out one cycle can be the active choice
There is no prize for applying in 2027 simply because the application window exists. If your priority status is unresolved, your evidence is thin or your only acceptable specialty filled from the priority group, sitting out a cycle may be the more disciplined decision.
Give the year a job. Decide what must be different by the next application: perhaps a stronger clinical reference, an accepted postgraduate exam, workplace evidence, or enough NHS experience to know which career you want. Pick the two changes that would alter your position. A list of twelve hopeful CV additions tends to produce twelve half-finished additions.
Keep an eye on recruitment, but don't spend the whole year in waiting mode. Read the person specification for the level you intend to enter. Arrange a career meeting with someone who understands that specialty's training and Portfolio routes. If the MSRA will still form part of your next application, choose when preparation will start and what score evidence would make the attempt rational. And if the new regulations place the direct route beyond your personal time limit, use the year to build a different route instead of automatically repeating the same application.
Compare other countries on the job you could get
Australia, Canada, the Gulf and the US need to be compared separately. Each has its own registration rules, training bottlenecks and costs. Compare the job you could obtain, the specialty access after it, the effect on anyone moving with you and the time before independent practice. Use official regulator and recruitment pages. If another system fits you better, leaving the UK plan can be a sound decision. This page cannot turn that comparison into an emigration guide.
Put the decision on one page
Make a one-page route sheet with your present location at the top and two columns underneath: "worth doing without a 2027 training number" and "only worth doing if the regulations help". Put each job or exam you are considering into one column, with its cost, visa position, supervision and likely result beside it. Cross out anything that depends on an unpublished rule. One or two workable paths are enough.
