This research aims to verify the role of the organizational dependence of the internal auditor in achieving his professional independence on the administrative and economic public sector in Syria by filling in a questionnaire distributed to a random sample of employees in different sites and centers. The results of the field study confirm the validity of all study hypotheses which say that the internal auditor must be related to one of the parties proposed by the study which are: the Board of Directors, the central body of supervision and inspection, the Central Agency for Financial Control. However The internal auditor dependence to the central body of supervision and inspection had greater attention by the study sample, with a focus on the appointment process, which represents the biggest threat to the professional independence of the internal auditor from the viewpoint of the study samples.
