Smart Rules 

A smart audit is a ‘risk based’ audit based on pre-defined set of criteria as shown in the table below.

Information about Smart Auditing

  • Smart audits are designed to find potentially defective EPC.
  • Smart audit selection will focus on the data items, and associated evidence, relevant to the smart rule(s) that the lodgement has triggered.
  • If a smart audit fails for a reason another than the smart audit rule that it triggered then, where possible, the subsequent follow on audit will be based on the same criteria that caused the fail.
  • If an EPC is called for smart audit and triggered multiple smart audit rules, then it will be audited against them all but only counted as one smart audit. 
  • If a member passes a smart audit then, in a subsequent month, they trigger the same smart audit rule then they do not need to be audited as they have already demonstrated their competence on the issue.
