You probably need a CREST form if you are applying to CT1 or ST1 and cannot show recent foundation competence through the UK Foundation Programme or another accepted training record. That includes most IMGs who have not completed the UK Foundation Programme and UK graduates whose Foundation Programme completion will be more than 3.5 years before the advertised post start date. You may also need it after voluntarily resigning if you are applying to a different specialty from the one you left. NHS England's applicant guide explicitly provides the ARCP route for reapplication to the same specialty, but does not give the equivalent statement for a change of specialty. The route for your own case depends on the detail in that guide.
You do not need CREST if you are currently in the UK Foundation Programme, because any offer is conditional on successful completion. Nor do you need it if you completed the programme within 3.5 years of the new post's start date, currently hold an NTN or DRN, or are reapplying to the same specialty and can use the permitted ARCP documentation from your previous training.
A Widening Access to Specialty Training (WAST) post defers the paperwork. You submit no further foundation-competence information at application, but must hold a fully completed and signed CREST by the start date of the post you applied for.
If you started but did not finish the UK Foundation Programme, you cannot use CREST at all. That includes starting an FY2 standalone post without completing it, or completing only an F1 standalone post. NHS England's expectation is that you return to the Foundation Programme. In exceptional circumstances such as illness or caring responsibilities, a Postgraduate Dean's letter on the standard proforma replaces CREST as the substitute document; it is not a supporting letter added to the certificate.
CREST provides evidence of foundation competence. Priority status for 2027 recruitment and the rest of the specialty person specification remain separate. If you are applying from outside the UK or trained abroad, our MSRA guide for IMGs covers eligibility, prioritisation and whether an application is likely to reach an offer.
Only the 2024 form is accepted
An old 2022 or 2023 CREST form will be rejected even if every answer is complete and the same consultant signs it. The current Word document is available from NHS England's CREST page; a saved copy from a previous application round may be obsolete.
The September 2024 re-release added an applicant checklist and remains a 2024 form. Both releases of the 2024 version count. The version named on the certificate determines whether it is current; the date when somebody emailed the file does not. Check the version before the form travels between you and your assessor.
An obsolete form discovered after signatures, stamps and registration evidence have been assembled leaves very little room to recover.
Job title alone does not make a signatory eligible
The phrase "consultant or equivalent" is narrower than it sounds. Under the official signatories' guide, an eligible signatory can be:
- a consultant;
- a GP;
- a Clinical Director or Medical Superintendent;
- an Academic Professor;
- a locum consultant with CCT or CESR who is currently on the GMC Specialist Register;
- a Specialty and Specialist (SAS) doctor acting as an educational supervisor.
A senior job title by itself is not enough. The signatory must hold the current registration required for that role, and your application must include evidence of it. A retired consultant cannot sign because previous registration is no longer current, even if they supervised you while still practising. A locum consultant who is not on the Specialist Register cannot substitute experience for the stated registration requirement.
The supervision requirement is separate. Your signatory must have worked continuously with you for at least three months full-time-equivalent, and that period must sit within the 3.5 years before the advertised start date of the training post. A substantial working relationship from an older job does not qualify outside that window. A suitably registered consultant who has reviewed your portfolio without completing the required period of supervision cannot sign.
The assessor does not have to be based in the UK. An overseas consultant or equivalent can sign if the seniority and supervision conditions are met. Your application must include current evidence from the assessor's home medical regulator. Evidence that is not in English needs a certified English translation. Historic GMC registration does not replace evidence of current registration with the regulator that now governs the assessor's practice.
The signatory must also be independent. A spouse, partner or family member can never sign, however senior they are or however closely they have observed your work.
Every capability must be confirmed
Acceptance depends on every professional capability on the form being demonstrated. Your signatory may rely on appropriate evidence where they have not personally observed a capability, but they still have to make the judgement. If one entry says "unable to confirm", the certificate does not meet the eligibility requirement.
There is no partial credit, and stronger evidence elsewhere cannot compensate for a missing capability.
Before the form is completed, you need to establish whether the proposed signatory can confirm every capability from direct supervision or acceptable evidence. Any missing evidence needs to be available while there is still time. An optimistic tick asks the signatory to make a judgement they cannot support and puts your application at risk.
The completed certificate and required signatory-registration evidence must be uploaded to the application as one document before the deadline. Separate uploads, or missing pages sent later by email or post, do not meet the submission requirement. NHS England's CREST checklist provides the page-by-page reference for the final merged file. If a submitted CREST is flagged for a correctable error, the recovery window is only 72 hours from notification. The corrected form must be signed and dated by the original signatory, who needs to remain reachable after submission. The correction process cannot be used to find a different consultant or rescue a late certificate.
The common failure points are the wrong form version, missing proof for an overseas assessor, an ineligible signatory, one "unable to confirm", or a submission after the deadline. A final review of the merged document from the administrator's perspective can catch each one before submission.
CREST has no fixed expiry date
A valid CREST can be used in a future recruitment round provided its conditions still apply to the new intended start date. The 3.5-year window is recalculated against each post's advertised start date, so a certificate that worked for one round can fall outside the window for the next. Each application needs the supervision dates measured against its intended start date; a private expiry date on the file cannot replace that calculation.

Questions about CREST
Do you need CREST if you finished foundation years ago?
Usually, yes, if your UK Foundation Programme completion will be more than 3.5 years before the advertised start date and you do not have another accepted route such as a current NTN or DRN. The calculation uses the post start date; the application date is irrelevant. CREST has no single expiry date, but the 3.5-year supervision window moves with each intended start date and must be checked for every round.
Can an old consultant abroad sign it?
Yes, if they are an eligible consultant or equivalent, supervised you continuously for at least three months full-time-equivalent within the relevant 3.5-year window, and hold current registration with their home regulator. Your application must include evidence of that registration and a certified English translation where needed. They cannot be a family member.
What if one capability says "unable to confirm"?
Your application will not meet the foundation-competence requirement. Every capability must be demonstrated. A discussion with the signatory before submission can establish which evidence they are able to consider. If "unable to confirm" remains on the submitted form, strength elsewhere does not compensate for it.
