The key purpose of this research is to empirically investigate the relationships between audit competency and audit survival for the certified public accountants (CPAs) in Thailand. In this reason, audit competency is the independent variable and it is measured by four dimensions, namely audit knowledge, audit skills, audit improvement, and audit reliability. Audit Competency is hypothesized to be positively associated with the consequence variables such as effective audit judgment, efficient audit practice, audit report quality, and audit performance. Audit survival is the dependent variable of the research. Audit skepticism, social responsibility, and environmental turbulence are determined as the moderator variables. Audit ethics, audit attitude, audit experience, audit change and stakeholder expectation are assigned as antecedents of audit competency. The sample of the study was 117 CPAs in Thailand. The results found that audit competency in dimension of audit skills, audit improvement, and audit reliability has a significant positive influence on effective audit judgment. Audit competency in dimension of audit reliability has an important positive impact on efficient audit practice. Effective audit judgment and efficient audit practice have an important positive impact on audit report quality. Efficient audit practice and audit report quality have the important positive impact on audit performance. Thus, audit performance has the important positive impact on audit survival. All of moderators in this study do not affect the aforementioned relationships. Theoretical and managerial contributions are explicitly provided. Conclusion and suggestions and directions of the future research are highlighted.
