This study analyzes the effect of brainstorming and auditor expertise on fraud risk assessment with auditor independence and organizational commitment as mediating variables. The research method uses a quantitative approach with a sample of 200 auditors from the Inspectorate General of the Ministry of Education and Culture. Data was collected through a questionnaire analyzed using the Structural Equation Modeling (SEM) method. The results of this study indicate that brainstorming has a positive effect on risk assessment, brainstorming has no effect on auditor independence, and brainstorming positively affects organizational commitment. Auditor expertise has a positive effect on risk assessment, auditor expertise does not affect organizational commitment, and auditor expertise positively affects auditor independence. Auditor independence has a positive effect on risk assessment, while organizational commitment does not affect risk assessment. The results of the mediation test show that auditor independence only has a mediating effect on the auditor's expertise in risk assessment.
