The purpose of this study was to examine the structure of tacit knowle
dge in the nursing profession. Using research in implicit learning and
practical intelligence as a theoretical framework, a paper-and-pencil
measure of tacit knowledge for nurses was developed and refined. Five
models, each representing an established theory of traditional intell
igence, were compared in terms of fit to the data. The results of the
confirmatory factor analysis suggest that Model 3, a hierarchical mode
l of intelligence, was the most plausible representation of tacit know
ledge in nursing. The results indicate that the portion of managerial
decision making learned implicitly on the job is mainly accounted for
by managing tasks and others. Suggestions for nursing education includ
e teaching effective strategies for managing tasks, such as handling i
ncreased workloads, establishing priorities, and delegating responsibi
lity.
