ACFE has updated the conviction question (starting at the application point, Step 3) on their awarding and carrying the credential:
Have you ever been convicted of any felony, or a misdemeanor involving moral turpitude, that you have not previously reported to the ACFE?
(“Moral turpitude” means an offense that calls into question the integrity or judgment of the offender, such as fraud, bribery, corruption, theft, embezzlement, solicitation, etc.)
Your application information will be sent to the ACFE, which stores your personal data in the U.S. to provide member services and fulfill transactions requested by you. For a full explanation of your rights regarding how ACFE stores and uses your data see: ACFE.com/privacy-policy.aspx.
