HIPAA pre-audit/readiness assessment

I have a client that wants me to perform a HIPAA readiness review. They want to see how they will do if they have a HIPAA audit. I cant find any information.

Is there a HIPAA auditor certification (IT or privacy)?

If the client is selected for a HIPAA audit, what will they be “audited on” (IT & privacy)?

What are testing criteria?

I amtrying to perform a “preaudit” to determine if they would pass a HIPAA audit.

What are testing metrics?
