The Single Audit is a comprehensive financial statement and federal awards audit which must be completed by the State of Washington each year. The Single Audit is performed to ensure the State uses federal funds appropriately and is in compliance with all applicable requirements and regulations of each grant award. Federal expenditures by all state agencies, including institutions of higher education, are included in the scope of the statewide Single Audit.

The audit is conducted by the State Auditor's Office pursuant to provisions of the federal Office of Management and Budget's Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards.
