Eighty hours is the number everyone remembers. The 24 sitting inside it is where compliance usually breaks.
Government Auditing Standards, the GAO publication almost universally called the Yellow Book, sets continuing professional education requirements for auditors performing work under generally accepted government auditing standards. The obligation attaches to the work being performed, not to a job title or an employer.
Who the Requirement Reaches
Auditors who plan, direct, perform field work for, or report on an audit or attestation engagement conducted under GAGAS fall inside the CPE requirements.
That framing catches people who don’t describe themselves as government auditors. A manager reviewing workpapers on a single audit falls inside it. So does a partner signing a report on a nonprofit that received federal awards, and a specialist brought in for one phase of a performance audit. The standards care about the function, not the business card.
The Structure
Each auditor performing work under GAGAS completes at least 80 hours of CPE every two years that directly enhance professional proficiency to perform audits and attestation engagements. At least 24 of those 80 hours cover subjects directly related to government auditing, the government environment, or the specific or unique environment in which the audited entity operates. At least 20 of the 80 are completed in any one year of the two-year period.
| Requirement | Hours | Measured over |
|---|---|---|
| Total CPE | 80 | Every 2-year period |
| Government subject matter | 24 of the 80 | Every 2-year period |
| Remaining professional expertise | 56 of the 80 | Every 2-year period |
| Annual minimum | 20 of the 80 | Each year of the 2-year period |
The 24 hours are a subset, not an addition. Under paragraph 4.16 of the standards the 80-hour total splits into 24 hours of government-related subject matter and 56 hours of subject matter that directly enhances professional expertise to conduct engagements. Paragraph 4.17 carries the 20-hour annual floor.
What Counts as Government CPE
The government subject matter category is wider than its name suggests. Three separate routes qualify: the government environment, government auditing itself, and the specific or unique environment in which the audited entity operates.
That third route gets underused. An auditor whose client base concentrates in a particular sector can count subject matter education about that sector toward the 24 hours, even where the course carries no government label at all. The qualifying question is whether the subject matter relates to the environment the audited entity operates in, not whether a CPE sponsor tagged it as governmental.
Two Standards, One Auditor
Yellow Book CPE does not substitute for a state board requirement. It layers on top of one.
States handle the overlap differently. Florida, for instance, incorporates the Yellow Book CPE requirements by reference into its administrative code for CPAs involved in governmental audits, applying them to the in-charge person, anyone reviewing the working papers or report, anyone supervising others, and a sole CPA performing the work. That rule also permits the 24 hours of governmental CPE to count toward certain state course requirements.
Other states draw the lines elsewhere. Current requirements by jurisdiction are maintained at surgentcpe.com/cpe-requirements.
The 2024 Revision and Its Effective Dates
GAO issued the 2024 revision of Government Auditing Standards on February 1, 2024, superseding the 2018 revision and its April 2021 technical update. Chapter 5 was rewritten, moving from quality control to quality management, and application guidance was added to chapter 6 covering financial audits.
The 2018 Yellow Book remains effective until the 2024 revision is implemented. The 2024 revision applies to financial audits, attestation engagements, and reviews of financial statements for periods beginning on or after December 15, 2025, and to performance audits beginning on or after December 15, 2025. A system of quality management complying with the standards was required to be designed and implemented by December 15, 2025, with an evaluation of that system completed by December 15, 2026. Early implementation is permitted.
One deferral applies at the federal level. Because of the lapse in appropriations running from October 1, 2025 through November 12, 2025, a federal government audit organization may defer design and implementation of its system of quality management until no later than March 16, 2026, completing its evaluation no later than one year from the date of implementation.
Where Planning Goes Wrong
Back-loading is the classic failure. An auditor who earns 70 hours in year two and 10 in year one has 80 hours and a broken requirement, because the 20-hour floor applies separately to each year of the period.
Mislabeling is the other one. Courses arrive tagged by NASBA field of study, not by Yellow Book bucket, and a general auditing course does not become government CPE because a government client happened to be the reason for taking it. Tracking the 24 hours as a distinct category from the start avoids a reconstruction exercise at the end of the period.
Two years is a long time to rely on memory.
Documentation and the Two-Year Window
The GAO does not collect CPE hours from audit organizations. Peer reviewers do look, and so do the state boards that incorporate the standards by reference, which puts the recordkeeping burden squarely on the organization rather than on any outside filing.
Audit organizations set their own two-year measurement periods, which means the period an individual auditor is measured against depends on the organization, not on a calendar the profession shares. Auditors who move between firms mid-period inherit whatever window the new organization runs on. Reconciling hours across that transition is one of the more common places a compliant auditor turns up short on paper.
