IAO periodically conducts follow-up audits of all audit recommendations made during an audit project. The follow-up audit is conducted to comply with auditing standards IAO follows and is typically conducted approximately 6 month to 2 years after the initial audit depending on the nature of the topics that IAO denoted during the original audit that received recommendations and based on IAO’s review of the corrective action plan management plans to implement in response to IAO’s recommendations. The primary purpose of the follow-up audit is to verify the department has implemented the corrective action plan and/or taken satisfactory other steps to mitigate the risk denoted in the original audit. During follow-up audits, IAO may interview staff, perform additional tests, and/or review new procedures to obtain reasonable assurance that the corrective actions have been implemented and are working effectively.
IAO will communicate the results of the follow-up audit to applicable management and the President of PSU. If the follow-up audit notes that further corrective action is needed, then a subsequent follow-up audit will occur until actions are completed and/or risks are mitigated to a reasonably low level. In addition, the results of follow-up audits are communicated to members of PSU’s Executive and Audit Committee two business days after the results are issued to the President of PSU, unless the Office of General Counsel advises differently.
