Intermediate Yellow Book Auditor Training: Single Audit Fundamentals

Author: Robert K Minniti

This intermediate level course provides auditors and compliance professionals with practical, hands on training covering the core requirements of Single Audits performed under the U.S. Government Accountability Office’s Yellow Book—formally known as Generally Accepted Government Auditing Standards (GAGAS)—and the federal Uniform Guidance (2 CFR Part 200, Subpart F). Single Audits are complex, high risk engagements that require auditors to apply sound professional judgment while navigating detailed federal compliance requirements and heightened reporting expectations. This course is designed for professionals who already possess foundational Yellow Book knowledge and are ready to deepen their Single Audit expertise.

Participants will gain a working understanding of the Single Audit framework, including determining applicability thresholds, identifying major programs using a risk based approach, and utilizing the Compliance Supplement to identify key compliance requirements. The course also addresses internal control over compliance, compliance testing procedures, evaluation of findings and questioned costs, and reporting responsibilities. Through real world examples and scenario‑based discussions, attendees will strengthen their ability to plan, perform, document, and report Single Audits in accordance with GAGAS and Uniform Guidance requirements.
