Following is a list of various professional services. Identify each by its apparent characteristics as audit engagement, attestation engagement, or assurance engagement. Because audits are a subset of attestation engagements, which are a subset of assurance engagements, choose the most specific description. In other words, if you believe the engagement is an audit engagement, select only audit engagement rather than checking all three. Similarly, the choice of assurance engagement for an audit, while technically correct, would not be the best choice.
