Information about financial statement errors is a principal component
of the auditor's knowledge base. While the effective organization of t
hese errors is thought to be important to audit performance, little is
known about the nature or development of the organization of an audit
or's knowledge. The two purposes of this study were (1) to empirically
determine the categories used by experienced auditors when they organ
ize financial statement errors on the basis of two dimensions suggeste
d in previous literature: transaction cycle and audit objective, and (
2) to determine whether there are experience-related differences in th
e organization of auditors' knowledge bases. To achieve these objectiv
es, a group of managers, staff auditors, and auditing students partici
pated in a card-sorting task. A better understanding of the structure
of auditors' knowledge could aid both practice and research because th
e category structures suggested in current auditing standards, auditin
g textbooks, and training materials appear to provide incomplete and i
nconsistent bases to organize financial statement error knowledge. The
results of this study are also compared to an often relied-upon categ
orization of financial statement errors suggested by Coakley and Loebb
ecke (1985). The results indicated that practicing auditors' categorie
s appear to be influenced by audit planning and testing procedures as
well as by the auditing literature. Staff auditors' categorizations by
transaction cycle were very similar to managers', but their audit obj
ective categories differed from those of the managers. The categorizat
ions of staff auditors (who have less experience planning audit tests
organized by audit objective) were more closely related to the auditin
g standards and textbooks, and did not include apparent refinements ev
ident in the managers' categories. Students were unable to categorize
errors based on their underlying meaning using either dimension, and i
nstead, sorted errors with similar wording into the same category. The
se results are consistent with psychological literature (e.g., Chi et
al. 1981) that suggests that more experienced individuals have better-
developed category structures. Implications of these findings for both
research and audit practice are discussed.
