Generally Accepted Auditing Standards: Audit Evidence – 1977

In February 1975, the CICA’s Auditing Standards Committee (AuSC) proposed, subject to comments received following exposure, to publish the contents of an Exposure Draft as CICA Handbook: Section 5100 - Generally Accepted Auditing Standards. In July 1976, the AuSC issued a 32-page Exposure Draft on “Internal Control” (for inter-related Sections 5200 to 5230).

Then, in May 1977, the AuSC issued a 12-page Exposure Draft on “Audit Evidence” (for Sections 5300). This material was intended to provide guidance, in general terms, as to the attributes of audit evidence and the manner in which the auditor obtains and evaluates such evidence to adhere to field work standard (iii) within generally accepted auditing standards. Field work standard (iii) states: “"Sufficient appropriate audit evidence should be obtained, by such means as inspection, observation, enquiry, confirmation, computation and analysis, to afford a reasonable basis to support the content of the report.”

The Exposure Draft emphasized that “The auditor is concerned with audit evidence in all phases of his audit engagement, from the planning stage, through the study and evaluation of internal control including the performance of compliance auditing procedures, to the performance of substantive auditing procedures.” It addressed the following matters: Introduction and Definition; Knowledge of the Business; Necessity for Performing Substantive Auditing Procedures; Sufficiency and Appropriateness of Evidence; Methods of Obtaining Evidence; Timing of Auditing Procedures; Errors and Irregularities; and Evaluation of Audit Evidence. In this regard, “The auditor relies on his professional judgment [emphasis added] in deciding which procedures will give him sufficient appropriate audit evidence. He evaluates the audit evidence gathered to determine the content of his report.”
