Policy statement

The MnDOT Office of Audit must comply with Generally Accepted Government Auditing Standards (Yellow Book). The Office of Audit provides independent and objective auditing, assurance, and management advisory services based on systematic examination of evidence to ensure that the agency’s operations, programs, and activities are operating as intended and in compliance with applicable state and federal requirements.

The Office of Audit has the authority to provide professional audit services department wide, regardless of MnDOT's organizational reporting structure, and is unrestricted in the scope of its audit work. To comply with Yellow Book standards, audit personnel must have full access to all sources of information deemed necessary by the Office of Audit to perform audits. The Office of Audit will comply with all applicable requirements to maintain confidentiality of data. Auditees must respond to requests for information from the Office of Audit and provide documentation by the established deadline.

The Office of Audit must also comply with the Minnesota Government Data Practices Act (Minnesota Statutes, Chapter 13). Any data determined to be classified as nonpublic or protected nonpublic must not be disclosed to any third party except as required by applicable state or federal law or pursuant to a court order. Data that are no longer needed for an audit are maintained in compliance with the Records Retention Schedule.

Independence and Objectivity

The Office of Audit must maintain independence and objectivity. Therefore, it:

  • requires each auditor to attest to their independence and objectivity annually and with each audit
  • conducts all engagement activities with integrity, objectivity, and independence to ensure engagement results have not been compromised
  • addresses external audit reports to the MnDOT office or district that requested the audit
  • addresses internal and highway construction audit reports to the Commissioner and Deputy Commissioners
  • provides management advisory services and feedback regarding the effectiveness of internal controls, but does not make operational decisions or implement controls

Reason for policy

This policy documents the MnDOT Office of Audit’s authority to conduct audits and investigations in compliance with Yellow Book standards.

Additionally, Minnesota Statutes §16A.057, subd. 8 states that the head of each executive agency is responsible for designing, implementing, and maintaining an effective internal control system within the agency.

This policy describes how the MnDOT Office of Audit fulfills its function to:

  • provide feedback regarding the adequacy and effectiveness of internal controls;
  • assess MnDOT’s compliance with applicable laws, rules, and regulations; and
  • help MnDOT accomplish its operational goals of excellence in customer trust, operational excellence, and workforce excellence.


All MnDOT offices, districts, and employees, third parties who have contracts with MnDOT, and subrecipients/grantees must comply with this policy.
