Revoked Mastery Badge Info

Why Was My Mastery Badge Revoked?

One or more of the challenges that was initially PASSED in earning the Mastery Badge has been revoked, meaning that its PASSED status was changed to FAIL and needs to be resubmitted according to challenge requirements. There are many reasons that lead to this status change, so refer to the feedback you received from the mentor in determining the specific scenario for your case.

Who Sees This Revoke Message?

Only you will see that a Mastery Badge has been revoked. As the owner of your own account, this message is only for you, to provide guidance in how to re-earn your Mastery Badge.

How Do I Fix A Revoked Mastery Badge?

Mastery Badges are earned when all of the requirements of a learning pathway have been completed successfully. To resolve your specific situation, go to the learning pathway that the Mastery Badge represents, and look at the additional requirements still pending for you to re-earn your Mastery Badge. Once resolved, you will be re-issued your Mastery Badge.
