The structure of the Standards is divided between Attribute and Performance Standards. Attribute Standards address the attributes of organizations and individuals performing internal auditing. The Performance Standards describe the nature of internal auditing and provide quality criteria against which the performance of these services can be measured. The Attribute and Performance Standards are also provided to apply to all internal audit services. Implementation Standards are also provided to expand upon the Attribute and Performance standards, by providing the requirements applicable to assurance (A) or consulting (C) activities. .
