Audit Office

The Audit Office provides independent advisory and assurance services to management and the Board. This includes audits, reviews, and evaluations of the Authority’s program and administrative control systems to determine if they are operating in accordance with management’s instructions, policies, and procedures to support strategic goals and objectives.

Internal audits strengthen the Authority’s ability to create, protect, and sustain value by providing the Board and management with independent, risk-based, objective assurance, advice, insight, and foresight.  

The Audit Office may perform: 

  • Performance Audits
  • Compliance Audits
  • Contract Compliance Audits 
  • Information Technology Audits 
  • Audit Follow-Ups 
  • Advisory Services 
  • Investigations

Audit Standards

The Audit Office adheres to the following professional standards: 

  • Government Auditing Standards – Also known as Generally Accepted Government Auditing Standards, (GAGAS), or the Yellow Book, issued by the Comptroller General of the United States, Government Accountability Office (GAO). Audits of federal funds are conducted in accordance with GAGAS. 
  • Global Internal Audit Standards – Also known as the Red Book, issued by The Institute of Internal Auditors (IIA).   
  • Other professional standards as recommended or required by the Office of Audits and Evaluations (Department of Finance), the California State Auditor and/or other State control agencies that may be applicable.

External Peer Review

To comply with both the Government Auditing Standards and the Global Internal Audit Standards, audit organizations are required to have an external peer review at least once every three years. The peer review determines whether an internal quality assurance system is in place and operating effectively. This provides reasonable assurance that established policies and procedures as well as appropriate auditing standards are followed. Most recent peer review for the period February 1, 2020 through January 31, 2023: Management Letter Independent Peer Review-Audit Office and Final Report Independent Peer Review-Audit Office.
