Internal Audit is an independent and objective review of County operations designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic and disciplined approach to reviews of its internal business processes, which results in independent recommendations designed to improve operational efficiencies, ensure compliance with applicable state and federal regulations and identify instances of fraud, waste or abuse of County assets.
Internal Audit follows the methodology outlined in the Internal Audit policies and procedures manual. Typical procedures utilized in an internal audit include:
Policies and Procedures
Upon completion of individual internal audits, the Internal Audit department will report findings to the Audit Committee and Board of Supervisors. Evidence of discussion and approval of Internal Audit findings can be viewed on the respective meeting agenda and minutes on the County website. Subsequent to obtaining Board approval, Internal Audit reports are published on the County website.
Internal Audit reports to the Audit Committee on a monthly basis and provides information related to the progress of current internal audits, planning and scoping of future internal audits and reporting of other ad-hoc items that are assigned to the Internal Audit department. Internal Audit provides quarterly reports to the Board of Supervisors including information such as the status of current year internal audits, results of the whistleblower hotline and other ad-hoc requests prescribed by the Board of Supervisors.
On a tri-annual basis, Internal Audit collaborates with the Board of Supervisors, Audit Committee, Elected Officials and key County Management personnel to perform a county-wide risk assessment. The results of the risk assessment are reviewed by Internal Audit and a proposed Internal Audit plan is developed and approved by the Board of Supervisors. On an annual basis, Internal Audit works with County Management and the Audit Committee to review the upcoming internal audits and determine if any new information is available that would result in a revision of the approved audit plan.
According to the Institute of Internal Auditors©, internal auditor independence is defined as,
"The freedom from conditions that threaten the ability of the internal audit activity to carry out internal audit responsibilities in an unbiased manner. To achieve the degree of independence necessary to effectively carry out the responsibilities of the internal audit activity."
In order for the Pinal County Internal Audit department to maintain its independence, its reporting structure has been modified to align with industry best practices. As a result, Internal Audit reports directly to the Board of Supervisors to ensure that no undue influence from County Management may result in compromising the independence of the internal audit function.

Additionally, Pinal County has established a silent whistle hotline for County residents or employees to report instances of fraud, waste or abuse.
