Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This article provides a comprehensive analysis of the impact of auditor independence and professional ethics on the quality of financial statement audits. The relevance of the study stems from the special role of auditing in ensuring the transparency and stability of the economic system. The accuracy and reliability of financial reporting are among the key factors determining the effectiveness of managerial decision-making. Therefore, the high quality of auditing primarily depends on the auditor’s adherence to the principle of independence and compliance with professional ethical standards. Auditor independence is a fundamental principle that reflects the auditor’s ability to express a professional opinion free from any external or internal influence. It ensures the objectivity and impartiality of the audit process. Professional ethics, in turn, encompass a set of principles that regulate the auditor’s integrity, fairness, professional competence, and responsibility. Compliance with ethical norms strengthens public and business confidence in the results of the audit. The paper examines the development of the audit institution in the Republic of Kazakhstan, the process of aligning it with international standards, and the legal and regulatory framework aimed at ensuring auditor independence. It also describes the negative consequences of breaching independence and violating ethical norms for audit quality, financial market stability, and organizational reputation. The results of the study demonstrate that auditor independence and professional ethics are the key guarantees of audit quality. The authors emphasize the importance of implementing comprehensive measures aimed at strengthening ethical culture, improving professional standards, and safeguarding the auditor’s independence.
