Historical Context
The International Standards on Auditing (ISA) are professional standards for auditing financial statements, established by the International Auditing and Assurance Standards Board (IAASB). The development of these standards dates back to 1978, reflecting a growing need for global consistency in audit quality and practice. Over the years, ISAs have been adopted by various countries and integrated into their national auditing frameworks.
Types/Categories
ISAs encompass several categories, each focusing on different aspects of the audit process:
- General Principles and Responsibilities: Guidelines on the overarching principles and the roles and responsibilities of the auditor.
- Risk Assessment and Response: Standards for assessing and responding to risks of material misstatement in financial statements.
- Audit Evidence: Rules on the nature and quality of audit evidence.
- Using Work of Others: Guidance on using work done by experts, internal auditors, and others.
- Audit Conclusions and Reporting: Standards for forming audit conclusions and preparing the auditor’s report.
- Specialized Areas: Standards dealing with specific issues like audits of smaller entities, group audits, and others.
Key Events
- 1978: Formation of the International Auditing Practices Committee (IAPC), the predecessor to IAASB.
- 1991: First issuance of a comprehensive set of ISAs.
- 2004: Establishment of the International Auditing and Assurance Standards Board (IAASB).
- 2009: The IAASB completed the Clarity Project, re-drafting the ISAs to enhance their understandability and applicability.
Detailed Explanation
