Aims: This study aims to analyze the influence of auditor-related factors, namely independence, competence, and professional ethics, on audit quality at the Audit Board of the Republic of Indonesia (BPK) Representative Office of North Sumatra. It also examines the moderating role of public information disclosure in strengthening these relationships. Study Design: The research adopts a quantitative explanatory design to test causal relationships between variables and the moderating effect of public information disclosure. Place and Duration of Study: The study was conducted at BPK Representative Office of North Sumatra, located in Medan, from April 2025 to July 2025. Methodology: Data were collected through questionnaires distributed to 156 auditors and employees involved in audit activities. The research employed Structural Equation Modeling with Partial Least Squares (SEM-PLS) to test validity, reliability, and hypothesis. Results: Findings indicate that auditor independence, competence, and professional ethics significantly influence audit quality.
