| Abstract: | The process of audit planning continues throughout an audit engagement. Preliminary audit plans are developed in the early phases of an engagement, and are revised in light of information received in subsequent phases, such as the results of substantive tests. This study examines the effects of (1) auditors' anticipation of finding a particular error-type in substantive tests and (2) the frequency of occurrence of the error-type on auditors' revision of preliminary audit plans. An experiment was conducted with practising auditors as subjects. Three error-types were manipulated as part of eighteen sets of exceptions from accounts receivable confirmations that each auditor reviewed. We found that auditors who do not anticipate finding an error-type in substantive tests are more likely to increase the amount of planned audit work. No effect of frequency of an error-type within a sample was found. |
