The GAO issued the 2018 version of Generally Accepted Government Auditing Standards Tuesday.
Find the online version here: https://www.gao.gov/
Find an audio summary of the changes to the standards here: https://www.gao.gov/
I suggest you scan chapter 4 and specifically section 4.16 to make sure you are compliant with the CPE requirements.
Also notice that the GAO has defined the roles of a supervisor and a reviewer inside the quality control chapter in sections 5.36-5.40.
And that the Green Book (Standards for Internal Control in the Federal Government) are mentioned several times in the document: 4.23, 6.30, 7.32, 8.41 & 8.130.
I’ll get back to you soon with a more thorough analysis of the changes and what they mean for you.
