What Certifications Should a Forensic Document Examiner Have?
When you hire a forensic document examiner, two things matter most: certification and proficiency testing. Here’s what to look for, and why it matters. Even examiners who built their skills inside a government agency or through on-the-job training benefit from independent certification, because it confirms their competence through an objective third party—not just their own say-so.
How Certification Works
In 2005, I founded the first international school of forensics. It had a two-year curriculum—in-person instruction, online coursework, and audio training modules. We train people using three textbooks, and then they sit for certification tests.
We now have a 100-question certification test, and it’s not open-book. They have to take it. They have to pass it. On top of that, we recommend going to a proficiency testing center. Organizations around the world will simply send you documents and already know who signed them and who didn’t. We developed our own proficiency tests for the school—ten of them now.

Building a valid proficiency test is harder than it sounds. You have to know, with absolute certainty, who wrote what. To build ours, we recruited volunteers, carefully documented who wrote each sample and who forged the others, and used that controlled set to measure a student’s ability to determine authorship. So make sure your expert is trained in that, and that the certification comes from a reputable organization—like ours, an international school.
What to Ask, and Why
If someone has never passed a proficiency test, or doesn’t hold a certificate, you have to wonder what their training actually was.
Worth noting: formal training programs in this field are still rare worldwide. There wasn’t an international school dedicated to forensic document examination until I founded one. So for the last hundred years, nearly everyone has been trained through work and on-the-job experience.

When you’re evaluating a potential expert—say, for a Tarrant County document dispute—look for three things: a certificate from a recognized training program, evidence they’ve passed independent proficiency tests, and confirmation that a judge has court-qualified them as an expert witness. Together, those three tell you a great deal about whether that person will hold up under cross-examination.

Frequently Asked Questions
What certifications should a forensic document examiner have?
Two things matter most: certification and proficiency testing. Even examiners trained inside a government agency benefit from independent certification, because it confirms competence through an objective third party — not just their own say-so.
How does certification work?
Reputable programs run a rigorous curriculum — textbooks, in-person instruction, online coursework — followed by a closed-book certification test (a 100-question exam that must be passed, not skimmed).
What is a proficiency test?
A controlled exercise where the testing organization already knows with certainty who wrote each document — built from carefully documented volunteer samples and forgeries — used to measure an examiner’s actual ability to determine authorship.
What should I ask a prospective examiner?
Whether they’ve passed a proficiency test and hold a certificate from a reputable organization. If they haven’t, you have to wonder what their training actually was — formal programs in this field are still rare worldwide.
