Internal Audit Reports

The County Auditor performs internal audits of the operations and finances of all officers, divisions, and departments under the jurisdiction of the DuPage County Board and the eight County-wide Elected Officials. These audits evaluate operations and finances and can assess weaknesses in County operations to help provide DuPage County taxpayers better services at lower cost. An audit report is provided to the management of the division or department, or to the Elected Official, to describe the conditions found and if appropriate, recommendations are made to correct weaknesses or vulnerabilities and to suggest improvements. When appropriate, these reports are also provided to the County Board and senior staff of the County.

Links to most internal audit reports can be found on this page, however some reports are not published, or have portions redacted, to protect an individual's privacy, to safeguard ongoing investigations or to avoid disclosing weaknesses that can be exploited by hackers and other bad actors, to the detriment of the County. Other similar reasons may apply in certain circumstances.

The internal audit reports below are presented in a rolling twelve-month period and are at least six months old at the time they are published online. Audit reports less than six months old are not published in order to afford the auditee an opportunity to address any issues identified in the audit. Typically, this page is updated monthly; with the addition of newer reports and removal of older reports. Reports are archived after they have been published for a one-year period. Archived reports remain available online - Archived Audit Reports.
