The results of this study indicate that the effectiveness of the audit committee and specialized industry auditors have a significant positive effect on audit quality. An effective audit committee is formed based on three attributes, namely: the number of members, audit committee meetings, and expertise. Those attributes will be able to carry out a monitoring role to ensure that the financial information submitted by the company has shown the actual condition of the company so that the quality of the audit produced by KAP will increase. Likewise, the use of industry-specialized auditors by companies will improve audit quality through auditors' knowledge and experience in the industry.
