Why was the peer review conducted?
Generally Accepted Government Auditing Standards (GAGAS) requires the Government Accountability Office (GAO) to obtain an external peer review at least once every three years.
The peer review determines whether GAO’s system of quality control is suitably designed and whether GAO is complying with its quality control system in order to achieve reasonable assurance of conforming to applicable professional standards.
Peer reviews of GAO’s financial audits were conducted beginning in 1995. Peer reviews of GAO’s performance audits were also conducted for 2004 and 2007, and combined peer reviews of GAO’s performance audits and financial audits were conducted for 2010 and 2013. This is the third combined peer review of GAO, covering the year 2016.
In 2016, GAO employed around 3,000 staff, organized across 14 mission teams. It issued 697 reports in 2016, around 95% of which Congress requested or mandated.
Who conducted the peer review?
An international team of auditors from the Supreme Audit Institutions of Denmark, Finland, New Zealand and United Kingdom carried out this peer review.
How was the peer review performed?
Between January and September 2017, the peer review team reviewed documents, examined a sample of audit reports, and conducted a case study, focus group meetings, interviews and three on site visits.

reasonable assurance that it is conforming to the sections of the
2011 GAGAS that apply to GAO’s performance and financial
