How to use the certificates on LinkedInHow the credential IDs work
One number per certificate
Every certificate downloaded with a name gets its own random nine-digit number. We store the name, test, result and date.
Cannot be changed afterwards
If someone edits the name or score in the PDF, the certificate no longer matches what is shown here.
Practice, not hiring
The tests are our own practice tests. The result is not the test provider's, and we never give an IQ score.
