Abstract The need for regular formalized staff training classes as a part of employee training has been fairly widely accepted by public accounting practitioners. In the article, the author presents his experience related to a large scale audit organization in the conduct of short intensive refresher courses for auditors at the in-charge level. Testing of capabilities of auditors in the application of theory to practice have been tabulated and preliminary inferences drawn from these results. The representative in-charge auditor carried into the courses a strong emphasis on voluminous vouching and checking as the prime means of obtaining adequate audit evidence. There was a marked resistance to change by a significant portion of the men even upon demonstration of the patent unsoundness of some of their ideas about audit objectives. This intransigence required early and intensive diversification of teaching techniques. Statistical measurements of progression superficially support the belief that early application of flexible, well-thought-out plans of instruction can aid in achieving significant improvement even as early as the second day of training.
