International Standards on Auditing (ISAs)

The auditor should follow basic principles and essential procedures together with related guidance as contained in ISAs. International Standards on Auditing (ISAs) are issued by the International Auditing Practices Committee (IAPC). The IAPC is a standing committee of the Council of the International Federation of Accountants (IFAC), which was formed in 1977 and is based in New York. IFAC has more than 150 member bodies, representing over 2 million accountants in more than 100 countries, and membership of IFAC automatically confers.
The IAPC issued standards and statements on auditing and related services in order to improve the degree of uniformity of auditing practice and related services throughout the world. The IAPC works closely with its members and national standard setters in order to gain acceptance of international Standards of Auditing (ISAs). Member bodies have increasingly sought to align the national position with the international positions IFAC and the IASC have gained influence and recognition. Standard setters increasingly refer to the international position in their consultative documents as authoritative support for a particular view.
International auditing and accounting standards do not at present override local regulations. Neither IFAC nor the IASC can currently compel any organization to comply with international standards; nor are there specific sanctions where organizations claim to have complied with international standards, but have not done so. The preface to International Standards on Auditing and Related Services (ISA 100) states that IAPC guidance falls into two categories:
- International Standards on Auditing (ISAs): ISAs contain basic principles and essential procedures (identified in bold type black lettering), together with related guidance in the form of explanatory and other material (in plain type) including appendices. The basic principles and essential procedures are to be understood and applied in the context of explanatory and other material that provides guidance for their application. The text of a whole standard is considered in order to understand and apply the basic principles and essential procedures.
- International Auditing Practice Statements (IAPSs): In conducting an audit in accordance with ISAs, the auditor is also aware of and considers International Auditing Practice Statements (IAPSs) applicable to the audit engagement. IAPSs provide practical assistance to auditors in implementing standards and promote good practice. They are not intended to have the authority of standards. The auditor may also conduct the audit in accordance with both ISAs and auditing standards of a specific jurisdiction or country.
