Audit Reports

The Internal Audit Division conducts audits of County Departments, Special Districts, and Federal and State Grants.

Peer Reviews

The Internal Audit Division participates in the State Association of County Auditors Peer Review Program and receives an External Assessment or “peer review" once every three or five years. Peer reviews are conducted following standards and guidelines contained in the Institute of Internal Auditors (IIA) Quality Assessment Manual for the Internal Audit Activity.

Not only are peer reviews required for compliance with the IIA’s International Professional Practices Framework (IPPF) and Government Auditing Standards, but an unqualified peer review opinion assures the public of high-quality audits and transparency in government. The Internal Audit Division regularly achieves an unqualified or “Generally Conforms” opinion.
