Types of Review Engagements

Review engagements are a type of assurance service where an independent practitioner performs limited procedures to provide moderate assurance that financial or non-financial information is free from material misstatements. Unlike audits, which involve extensive testing and provide reasonable assurance, review engagements rely primarily on inquiries and analytical procedures, resulting in limited assurance. Review engagements are valuable for organizations that require a level of credibility in their reports without undergoing a full audit. They are commonly used for interim financial reporting, compliance checks, and non-financial disclosures.
