County Auditor Jurisdiction - a/k/a - Who do We Audit?

The elected County Auditor is chosen by the voters to independently evaluate DuPage County operations and finances.   The County Auditor does not report to the DuPage County Board, or the County Board Chair and therefore can conduct objective evaluations.  The results of these evaluations are the basis for making recommendations for improvement.  When appropriate, the results of these evaluations are reported to the DuPage County Board, the County Board Chair, other County-wide Elected Officials and the public. 

The jurisdiction of the County Auditor is established by Illinois statute.  Not all agencies or organizations that might seem related to DuPage County government are under the jurisdiction of the County Auditor.
