About this exam

The American Board of Medicolegal Death Investigators (ABMDI) is a voluntary, national, not-for-profit, independent professional certification board established to promote the highest standards of practice for medicolegal death investigators. ABMDI certifies individuals who have the proven knowledge and skills necessary to perform medicolegal death investigations as set forth in the National Institute of Justice 1999 publication Death Investigation: A Guide for the Scene Investigator (a 2011 updated version is available). The credential is aimed at practicing investigators in medical examiner and coroner offices - people who investigate suspicious, violent, unexplained, and unexpected deaths that fall under medicolegal jurisdiction, and who combine education and skills spanning medicine and law. The board was created and developed by veteran, practicing medicolegal death investigators who took part in developing that NIJ guide, and it has been accredited by the Forensic Specialties Accreditation Board since 2005, with reaccreditation in 2010, 2015, 2020, and 2025. Exam content tracks the work itself: jurisdiction and legal authority, scene investigation and documentation, decedent examination, identification and property, death circumstances and injury interpretation with follow-up, and reporting, death certification, ethics, and professional practice. Preparation should center on the 29 tasks identified in the national guidelines - developed by a working group of 24 experts plus 146 national reviewers - supplemented by hands-on case experience and formal death investigation training courses. Item count, time limit, fee, passing score, and retake rules are not published on the board's site reviewed here; confirm those in the official candidate handbook before scheduling.

What you'll study

Common questions

About ABMDI Board (F-ABMDI) preparation

What standards is the ABMDI certification exam based on?

ABMDI certifies individuals who have the proven knowledge and skills necessary to perform medicolegal death investigations as set forth in the National Institute of Justice 1999 publication Death Investigation: A Guide for the Scene Investigator, with a 2011 updated version available. Build your study plan around that document rather than around general forensic textbooks.

Do I need a degree to sit for certification?

There are no formal educational requirements specifically for medicolegal death investigation, according to ABMDI. Degree programs in forensic science, natural science, anthropology, nursing, or another medically related field would be useful, and several established training courses around the country teach the basic information needed to perform a thorough, competent investigation.

Are there formal requirements to become a medicolegal death investigator?

No - ABMDI states there are no formal requirements, and each coroner and medical examiner office has different hiring practices. An investigator must be knowledgeable of local, state, and federal laws, and must be the most medically knowledgeable person at the scene in order to determine whether further investigation is necessary.

How many questions are on the exam, how long is it, and what does it cost?

Those specifics are not published on the ABMDI website reviewed here, so treat any number you see elsewhere as unverified. Request the official candidate handbook from the board for the current item count, time limit, fee, passing standard, and retake policy before you schedule.

What content areas should I study, and in what order?

Work through the 29 tasks identified in the national guidelines, which form the task basis for the credential. Organize study by practice area: jurisdiction and legal authority; scene investigation and documentation; decedent examination, identification, and property; death circumstances and injury interpretation; and reporting, death certification, and ethics.

Who actually writes the standards behind the exam?

The national guidelines were developed by a working group of 24 experts in medicolegal death investigation, including members of the Forensic Panel (NMRP), and 146 members of the TWGDI national reviewers network. ABMDI itself was created, designed, and developed by veteran, practicing medicolegal death investigators involved in that guide.

How do I know the credential is legitimate?

The ABMDI was first accredited by the Forensic Specialties Accreditation Board in 2005 and was reaccredited in 2010, 2015, 2020, and 2025. FSAB exists so the forensic community can assess, recognize, and monitor organizations or professional boards that certify individual forensic scientists or other forensic specialists.

How does the investigator's role differ from law enforcement at a scene?

ABMDI draws a clear line: the medicolegal death investigator is responsible for the dead person, while the local law enforcement jurisdiction is responsible for the scene. The investigator performs scene investigations emphasizing information developed from the decedent and determines the extent to which further investigation is necessary. Expect jurisdiction questions to test that boundary.

What trips candidates up most often?

Weak spots typically show up where medicine and law overlap: legal authority and jurisdiction, and the discipline of documenting the scene and decedent thoroughly enough to support later follow-up. Because the investigator must be the most medically knowledgeable person at the scene, do not neglect injury interpretation and the reasoning behind whether further investigation is needed.

Is this page affiliated with ABMDI, and does the exam have announced changes?

No - this is independent study material, not an official ABMDI product, and the board's opinions are its own. No announced changes to item count, time limit, passing standard, fee, retake policy, or recertification cycle appear in the source reviewed, so verify all of those directly with ABMDI.
