How to Validate Certificates in Tags? : Smartapp.com

The 'Skills/Cert/Work Category' in the add tag will allow you to add the "Verify Certification at start of work' to the Tag.

Once the "Verify Certification at start of work' checkbox is checked you are displayed another option "Certifications required: All or Any"

Selecting Any in the Certification Required section will check for valid certificate from one or more selected certificates before start of work.
Selecting All in the Certification Required section will check for all the valid certificate selected before start of work.

Once the Tag is submitted and dispatched in work queue based on the Resource Type configuration (Company/User) the validation on a task changes at the start of the work.
