A certified fraud examiner is a person who helps to catch people who are trying to steal or cheat others. They use special skills and knowledge to find evidence of wrongdoing and gather information that can be used in a court of law. Think of them as kind of like detectives who work to prevent bad people from doing bad things. To become a certified fraud examiner, a person has to go through special training and take tests to prove they know all about fraud and how to stop it.
