Independence and Objectivity

To ensure independence, Internal Audit Services reports administratively and functionally to the State Auditor consistent with its enabling legislation. The State Auditor provides direct oversight, including approval for release of engagement reports. Internal Audit Services will work collaboratively with SCDOT leadership in developing an audit plan that appropriately aligns with SCDOT's mission and business objectives and reflects the business risks and other priorities identified by leadership and Internal Audit Services. To ensure objectivity, Internal Audit Services is not involved in the day-to-day operations or internal control procedures of SCDOT and has no direct responsibility or managerial authority over the programs and activities of SCDOT.

The scope of Internal Audit Services' work includes the review of risk management, internal control, information systems, and governance processes through the provision of assurance services (defined as objective examinations of evidence for the purpose of providing an independent assessment) and consulting services (defined as advisory activities, the nature and scope of which are agreed with management). This work also involves periodic testing of transactions, best practice reviews, investigations, appraisals of legal and regulatory requirements, and measures to help prevent and detect fraud.

The results of each audit will be reported through a detailed audit report that summarizes the objectives and scope of the audit as well as observations and recommendations. In all cases, follow-up work will be undertaken to ensure adequate response to management's proposed risk responses and/or Internal Audit Services recommendations. Internal Audit Services reports will be delivered to the State Auditor for approval prior to distribution to the SCDOT Commission and the Legislative committee chairs identified in SC Code Section 57-1-360(B)(2).
