The American Board of Forensic Document Examiners, Inc. (ABFDE) is a non-profit organization which provides third-party certification of professional forensic document examiners (FDEs) from Canada, Australia, New Zealand, and the United States of America, and other countries if approved by the board of directors.

Individuals holding a valid Certificate of Qualification issued by the ABFDE use the designation "Diplomate of the American Board of Forensic Document Examiners", often abbreviated as D-ABFDE.

However, courts have recognized the ABFDE as reputable in the following cases, in denying a motion that claimed that handwriting comparisons were unreliable: John J. Harris sat as the inaugural chairman in 1977, and in the following year, the Committee of Certification was created.

As of 23 February 2024, 82 Diplomates are listed as being certified examiners working in private, federal, state and local government laboratories.

Additionally, the Diplomate applying for recertification must earn at least 40 continuing education credits to demonstrate that s/he has maintained currency in the profession.
