As required by the federal Single Audit Act, each year the California State Auditor's Office reviews and evaluates how well state entities administer federal programs. As a first step, the California State Auditor follows up on previously reported issues. The auditee provides us with written responses with regards to corrective action it asserts it has taken to remedy the weaknesses we have identified in prior Single Audit reports. In addition, we review documentation and/or perform tests to confirm whether the described corrective action was taken and corrected the deficiency. For 2007 through 2018, we have created a table that summarizes the number of issues that we reported in our Single Audit reports that had not been corrected at the time of those reports.
