Question Regarding the Audit

After i pass the exam is there a possibility i could be Audited in the future or is the Audit just for when you apply to take the exam. If they do audit me in the future what are they checking for? Would they just want to see my continuing education credits or are they contacting my references a second time to verify i have the necessary experience?  I am confused as to what the audits would consist of once i pass the exam. 

 

Thanks
