The Quality Assurance Working Group (QAWG) was established in 2016 to help enhance the efficiency and effectiveness of Quality Assurance throughout the Federal OIG community.  In 2019, CIGIE formally recognized the Working Group as part of its Federal Audit Executive Council (FAEC).

CIGIE’s Quality Standards for Federal Offices of Inspector General (Silver Book) requires each Office of Inspector General to establish and maintain a quality assurance program to ensure that work performed complies with established OIG policies and procedures; meets applicable professional standards; and is carried out economically, efficiently, and effectively.
