FieldCred does not verify certifications automatically. Neither NCCER nor OSHA offers a public API a third party can query — NCCER's Online Verification is a login-gated, lookup-by-card-number tool on their own site, and OSHA 10/30 verification is fragmented across whichever Authorized Training Organization actually issued the card. There's no single "check this card" button FieldCred can press on your behalf.
Instead, Verified records that a real person — an admin — looked the card up on the source's actual portal and confirmed it. Checking the box stamps:
- verifiedBy — the signed-in admin's email, at the moment they checked it.
- verifiedAt — the timestamp.
/r/:slug record. The public view omits verifiedBy — an admin's email is staff contact info, and that page is deliberately built to never expose it.
Why it clears itself
Verification is an attestation about one specific source-and-card-number pair, not a standing fact. Changing the verification source or the card number on a cert that's already verified automatically un-checks it — you're now looking at a different claim, and re-confirming it is a deliberate act, same as the first time.
See Verifying an NCCER or OSHA card for the actual lookup steps.
