Updated October 2026 · 5 min read

D551 Fraud and Forensic Accounting shows how fraud occurs and how accountants detect, investigate and prevent it. It appears in WGU's Master of Science in Accounting, Auditing Specialization.

WGU describes an in-depth understanding of how fraud and forensic investigations form part of the accounting profession, covering types of fraud, their impact, detection, investigation and prevention, and the role of forensic accountants in the legal system.

The course includes scenarios and hands-on exercises. The challenge is to apply the concepts to a specific case and justify each step.

Key Concepts Explained

The Fraud Triangle

Fraud commonly involves pressure, opportunity and rationalization. Prevention aims to remove opportunity through controls and to reduce pressure and rationalization through culture.

Example: A bookkeeper under personal financial pressure finds that she alone approves and records vendor payments. That gives her opportunity. She tells herself she will repay the money. Splitting the approval and recording duties, and reviewing vendor changes independently, removes the opportunity.

Investigation Steps

A typical investigation preserves evidence, analyses records, interviews relevant people and reports findings objectively. Document each step so the work can be reviewed.

Prevention and Deterrence

Strong controls, clear policies, a reporting channel and visible consequences all help deter fraud. Explain which control addresses which scheme.

Typical Assignments and How to Approach Them

Your task instructions state the format. Work in this course typically involves:

Prevention adviceControl designLink each fix to a weakness

A Second Worked Example

Spotting Red Flags in a Case

Consider a small company where one employee handles purchasing, receiving and payment approval and has never taken leave.

Example: These facts are red flags for a fake vendor scheme. Segregation of duties is absent, and the lack of leave means no one else sees the process. An investigator compares vendor lists with employee addresses, checks for invoices just under approval limits and reviews supporting documents. Recommendations include separating duties, rotating tasks and requiring independent vendor approval.

Self-Check Before You Submit

The case is illustrative and not a real company.
