Sample certificate
This is the certificate issued when an assessment is finalised. It carries illustrative data and a watermark: the sample certificate ID is not a real credential, so verifying it returns "not valid".
Available on your own certificate.
Frozen facts
The name, assessment, completion date and result wording are recorded at issue and cannot be edited afterwards. A correction is issued as a superseding certificate, so a verifier can always see that a change was made.
Verification
Each certificate has its own verification page, which names its holder in full. The holder chooses whether the certificate and their result are published, or kept private.

It is not a qualification and not an authorisation. It confirms completion of a technical knowledge assessment and does not replace statutory registration or employer sign-off.
