Audit morality is a key determinant of driving and explaining best audit practice that influences audit
performance. Accordingly, this study attempts to investigate the relationships between audit morality and
audit performance. Then, this study aims at examining the effects of audit morality on audit performance
of certified public accountants (CPAs) in Thailand. Audit morality includes moral sensitivity, moral
judgment, moral motivation, and moral character. In this study, 113 CPAs in Thailand are the sample of
the study. To clearly verify the aforementioned relationships, the results of this study show that (1) moral
sensitivity is positively related to audit performance, (2) moral judgment is positively associated with audit
performance, (3) moral motivation is positively interacted with audit performance, and (4) moral character
is positively connected with audit performance. In sum, audit morality outstandingly plays a significant role
in determining audit performance. Also, all dimensions of audit morality (moral sensitivity, moral judgment,
moral motivation, and moral character) are the antecedents of audit performance. Potential discussion is
efficiently implemented in the study. Theoretical and professional contributions are explicitly provided.
Conclusion and suggestions and directions for future research are also highlighted.
