Hello Michael House,
Apologies for the delay in my response.
I understand your concern, as highlighted below currently we cannot start the assessment as its under ongoing maintenance.
Certainly, we don't have an estimated time for its availability again, Microsoft Support Team is working diligently on it. we will be notifying when it gets available again for the assessment.
Please note that the status post for Applied Skills Assessment Status is regularly updated with the latest information as soon as it becomes available. We highly recommend checking it periodically.
For you reference please refer to the below link.
We greatly appreciate your understanding on this matter.
