Hi @kimwin,

Hope you're doing well!

You can check if your certification is expired or not in ServiceNow University (Now Learning) under My Profile > Credentials.

In Web assessor, earlier we were having certification date and expiry date under My Certifications, currently the information is incorrect on that site, the webassessor team is working to fix it.

You can submit a case on NowLearning Portal if you would like to get more details about your certification expiry 
Help Center - ServiceNow University

Best Regards,

Sharif
