Which of the following is NOT a type of assurance engagement?

In the context of assurance engagements, they are designed to enhance the degree of confidence of intended users in the outcome of an evaluation or measurement of a subject matter against criteria. Review, compilation, and audit engagements are well-recognized forms of assurance services provided by auditors.

A review engagement typically involves limited procedures and provides a moderate level of assurance, where the auditor expresses limited assurance on the financial statements. An audit engagement, on the other hand, involves a complete examination, providing a very high level of assurance through extensive testing and evaluation of evidence. A compilation engagement is the least rigorous type, where the accountant compiles financial statements based on information provided by management without expressing an opinion or assurance on them, but it still falls under the definition of assurance engagements.

In contrast, an evaluation engagement is not formally defined as a type of assurance engagement within the auditing standards. While it may involve assessing certain criteria or aspects of a subject matter, it does not fit within the established framework of assurance engagements like reviews, audits, or compilations, which directly contribute to the assurance process. Thus, it is why this choice is identified as not being a type of assurance engagement.
