Generally accepted auditing standards (GAAS) comprises a list of
10 standards, divided into the following three sections:
A. General Standards
- The auditor must have adequate technical training and
proficiency to perform the audit.
- The auditor must maintain independence in mental attitude in
all matters relating to the audit.
- The auditor must exercise professional care in the performance
of the audit and the preparation of the report.
B. Standards of Field Work
- The auditor must adequately plan the work and must properly
supervise any assistants.
- The auditor must obtain a sufficient understanding of the
entity and its environment, including its internal control, to
assess the risk of material misstatement of the financial
statements whether due to error or fraud, and to design the nature,
timing, and extent of further audit procedures.
- The auditor must obtain sufficient appropriate audit evidence
by performing audit procedures to afford a reasonable basis for an
opinion regarding the financial statements under audit.
C. Standards of Reporting
- The auditor must state in the auditor's report whether the
financial statements are presented in accordance with generally
accepted accounting principles.
- The auditor must identify in the auditor's report those
circumstances in which such principles have not been consistently
observed in the current period in relation to the preceding
period.
- When the auditor determines that informative disclosures are
not reasonably adequate, the auditor must so state in the auditor's
report.
- The auditor must either express an opinion regarding the
financial statements, taken as a whole, or state that an opinion
cannot be expressed, in the auditor's report. When the auditor
cannot express an overall opinion, the auditor should state the
reasons therefore in the auditor's report. In all cases where an
auditor's name is associated with financial statements, the auditor
should clearly indicate the character of the auditor's work, if
any, and the degree of responsibility the auditor is taking, in the
auditor's report.
