Historical Context
International Standards on Auditing (ISAs) are professional standards for auditing financial statements, issued by the International Auditing and Assurance Standards Board (IAASB). These standards provide a framework for auditors to ensure that their audits are conducted with consistency, transparency, and reliability. The origins of ISAs date back to the mid-20th century when the need for uniform global auditing standards became apparent as businesses expanded internationally. The IAASB, a body of the International Federation of Accountants (IFAC), has been pivotal in developing and maintaining these standards.
Types/Categories
ISAs are broadly categorized based on different aspects of the auditing process:
- General Principles and Responsibilities (ISA 200-299): These ISAs cover the fundamental principles and responsibilities of auditors, including ethical requirements and professional skepticism.
- Risk Assessment and Response (ISA 300-499): These ISAs focus on planning the audit and assessing risks to design audit procedures.
- Audit Evidence (ISA 500-599): These ISAs deal with obtaining and evaluating audit evidence to form an audit opinion.
- Using Work of Others (ISA 600-699): These ISAs provide guidelines on using the work of internal auditors and other auditors in the audit.
- Audit Conclusions and Reporting (ISA 700-799): These ISAs address forming and expressing audit opinions on financial statements.
- Specialized Areas (ISA 800-899): These ISAs cover audits of specific types of financial statements, such as compliance audits and audits of financial statements prepared using special-purpose frameworks.
Key Events

Detailed Explanations
General Principles and Responsibilities (ISA 200-299)
These ISAs emphasize the importance of ethics, independence, and professional skepticism. For example, ISA 200 lays down the overall objectives of an auditor and explains the conduct of an audit in accordance with ISAs.
Risk Assessment and Response (ISA 300-499)
These standards guide auditors in planning an audit and assessing risks of material misstatement. ISA 315 (Revised) focuses on identifying and assessing the risks of material misstatement through understanding the entity and its environment.
Audit Evidence (ISA 500-599)
These standards elaborate on the nature and extent of audit evidence that auditors need to gather. ISA 500 describes the objective of an auditor to design and perform audit procedures that are necessary to obtain sufficient appropriate audit evidence.
Using Work of Others (ISA 600-699)
These ISAs provide guidance on using the work of an entity’s internal auditors and other external auditors. ISA 610 addresses considerations when using the internal audit function’s work.
Audit Conclusions and Reporting (ISA 700-799)
These standards cover forming audit opinions and reporting on financial statements. ISA 700 deals with the auditor’s responsibility to form an opinion on financial statements based on the evidence obtained.
Importance and Applicability
ISAs are critical for ensuring consistency and transparency in audits globally. They help maintain public confidence in the accuracy and reliability of financial statements, which is essential for the proper functioning of capital markets.
Examples and Considerations
