What type of assurance engagement involves the practitioner expressing a positive form of conclusion?

The correct answer is reasonable assurance engagement. In this type of assurance engagement, the practitioner is required to provide a high level of assurance regarding the subject matter, and this is typically conveyed through a positive form of conclusion. This means that the practitioner expresses a conclusion that provides assurance that the information is free from material misstatement, according to the relevant criteria.

Reasonable assurance engagements often involve detailed procedures, assessments, and evaluations, allowing the practitioner to gather enough sufficient appropriate evidence to support their conclusion. The result is a thorough and reliable opinion that enhances the credibility of the subject matter being examined.

In contrast, limited assurance engagements provide a lower level of assurance and involve less extensive procedures. Negative assurance engagements do not provide an opinion but rather state that nothing has come to the practitioner's attention that indicates a material misstatement. Verification assurance engagement is not a recognized term in auditing standards and does not correspond to a specific type of engagement recognized in the field.
