- RC here means Registry Certification (basic) from the American Board of Medicolegal Death Investigators (ABMDI), not any other credential sharing the letters.
- The exam has 240 multiple-choice questions: 230 graded, ten unscored pilot items, in four hours with live virtual proctoring.
- Seven weighted sections apply; Forensic and Medical Knowledge is largest at 20%, and each section carries its own passing standard.
- Eligibility rests on 640 points within five years, including at least 384 employment points, not a flat 640-hour rule.
What "RC" Means on This Site
The letters "RC" show up in dozens of professional contexts, which is why a search for the abbreviation returns a muddle of unrelated credentials. On this site, RC means Registry Certification (basic): the entry-level certification pathway offered through the American Board of Medicolegal Death Investigators. "RC" is the shorthand we use here for convenience; it is not an official exam code issued by the board, and you will not see it printed on an ABMDI certificate.
If you landed here looking for a different meaning of the abbreviation, none of what follows (the exam format, the fees, the eligibility rules, the content areas) transfers to that credential. If you work, or intend to work, as a medicolegal death investigator, you are in the right place. For related definitions, our pages on what RC is and what RC stands for cover the same ground from other angles.
Who Issues the Credential
The American Board of Medicolegal Death Investigators (ABMDI) is the certifying body. Its Registry program recognizes investigators who have demonstrated baseline competence in the core work of death investigation: responding to scenes, assessing and documenting the body, communicating with agencies and families, and understanding the forensic and medical concepts that underpin a determination of cause and manner of death.
The governing documents are public. The exam blueprint sits in Appendix C of the ABMDI Policy and Procedure Manual (June 2024, revision 24.5.31), and the application, eligibility, proctoring, and retest process is documented in the Registry Certification Application Process guide (revision 24.6.1). A third document, Fundamental Tasks of Medicolegal Death Investigation, defines the competencies a trainer must verify. Its printed revision is 23.8.24 even though the filename carries a 2024 label, so check the revision line rather than trusting the filename when you cite it.
Registry vs. Board Certification
The most common source of confusion for newcomers is the difference between the basic Registry pathway and ABMDI's advanced Board Certification. They are distinct tracks with distinct credentials.
| Feature | Registry Certification (basic) | Board Certification (advanced) |
|---|---|---|
| Credential designations | Associate (A-ABMDI) and Diplomate (D-ABMDI) | Fellow (F-ABMDI) |
| Level | Basic / entry pathway | Advanced |
| Exam format covered in this article | 240 multiple-choice questions, proctored virtually | Separate process, not covered here |
| Scene-experience distinction | Diplomate reflects documented scene experience; Associate covers the no/limited-scene route | Not applicable to this comparison |
Within the Registry pathway, the Associate and Diplomate designations differ mainly in scene experience. Associate status covers investigators whose work involves no scene response or limited scene response, while Diplomate reflects a documented body of scene work. This article does not describe the practical or case-based examination associated with Board Certification; that is a different program with its own requirements.
How the Exam Is Built
The Registry examination is a single computer-based test of 240 multiple-choice questions. Of those, 230 are graded and ten are unscored pilot questions used by the board to evaluate future items. You will not know which are which, so every question deserves a full effort. You have four hours, and the session is monitored through live virtual proctoring via MonitorEDU.
Two structural facts shape how you should prepare:
- Scoring is section-by-section. Each of the seven sections must meet its own criterion-referenced passing standard, set using the modified Angoff method, in which subject-matter experts judge how a minimally competent candidate would perform on each item. There is no single advertised raw percentage that guarantees a pass, so be wary of any resource that gives you one. Our RC passing score guide explains what is and isn't publicly specified.
- Strength in one area doesn't rescue weakness in another. Because each section is held to its own standard, a candidate who is excellent at scene work but shaky on forensic and medical concepts cannot simply trade one off against the other.
The questions test applied judgment. Expect scenarios that ask what an investigator should do, document, or communicate in a given situation, alongside knowledge items on anatomy, pathology, toxicology concepts, and death-investigation terminology. Pair the blueprint with realistic practice questions; the main RC practice test site is built around this scenario-plus-knowledge style.
The Seven Content Areas
The current seven-section structure took effect on January 1, 2024, replacing older descriptions that used eight sections. If you are studying from an older book or a colleague's notes, check that they reflect the current blueprint. Here is how the weight breaks down, and what each area demands.
| Domain | Weight |
|---|---|
| Domain 1: Interagency Communication | 10% |
| Domain 2: Communication with Families | 10% |
| Domain 3: Scene Response and Documentation | 18% |
| Domain 4: Body Assessment and Documentation | 18% |
| Domain 5: Completing the Investigation | 14% |
| Domain 6: Additional Medicolegal Death Investigator Duties | 10% |
| Domain 7: Forensic and Medical Knowledge | 20% |
Forensic and Medical Knowledge (20%)
The heaviest section, and the one most likely to trip up investigators who learned the job through experience rather than formal science coursework.
- Anatomy and physiology as they relate to injury and disease
- Postmortem changes and how they inform time-of-death reasoning
- Categories of death mechanisms and how manner differs from cause
- Terminology you must use precisely in reports
Scene Response and Documentation (18%)
Tests the practical discipline of arriving at, securing, and recording a scene.
- Scene safety and preservation of evidence
- Systematic documentation: notes, photographs, and diagrams
- Recognizing what belongs in the record and what does not
Body Assessment and Documentation (18%)
Equal in weight to scene work, and focused on the decedent.
- Describing injuries, clothing, and identifying features accurately
- Distinguishing observation from interpretation in your notes
- Handling and tracking the body and associated property
Completing the Investigation (14%)
Covers what happens after the scene: gathering records, coordinating with the forensic pathologist or medical examiner, and finalizing the case file.
The Three 10% Sections
Interagency Communication, Communication with Families, and Additional Medicolegal Death Investigator Duties together make up 30% of the exam. They are easy to underestimate, but because each section has its own passing standard, ignoring them can sink an otherwise strong attempt.
- Interagency Communication: working with law enforcement, medical examiners and coroners, hospitals, and other agencies
- Communication with Families: notification, sensitivity, and appropriate information-sharing
- Additional Duties: responsibilities that fall outside the core scene-and-body workflow
For a section-by-section breakdown with sample topics, see our complete guide to all seven RC content areas.
Eligibility and the Points System
ABMDI does not simply ask how long you've held a job. Eligibility is built on a points system, and understanding it correctly saves you from applying too early or misreading the rules.
- Minimum age of 18 and a high school diploma or equivalent
- Current qualifying medicolegal-investigation employment
- 640 eligibility points accumulated within five years, including at least 384 employment points
- A professional reference and employer verification
- A trainer-verified attestation of competence in the Fundamental Tasks
The Diplomate scene-experience wrinkle
One genuine inconsistency in the source documents deserves a warning. For the Diplomate designation, the application guide states 100 documented scene hours, while the manual's eligibility table states 100 scene points. The manual also keeps "hours" wording elsewhere. Hours and points are different units and should not be treated as interchangeable. If you are pursuing Diplomate status, confirm the current requirement directly with ABMDI before you submit, and document your scene work thoroughly enough to satisfy either reading. Our RC requirements guide walks through the full prerequisite picture.
Fees, Proctoring, and Retests
The cost structure is simple. Per the policy manual's fee schedule, there is a $50 application fee and a $400 examination fee that includes proctoring. Those are the two figures to budget for at the outset; ongoing maintenance costs are covered below. A fuller picture of the financial side is in our RC certification cost breakdown.
Because grading is section-based, the retest rules are more forgiving than a single all-or-nothing score:
- If you fail one or more sections, you may retest twice.
- Retests must be separated by at least 30 days between testing dates.
- All attempts must fall within the 12-month application/testing window.
- You retest only the sections you failed, not the whole exam.
Key Takeaway
Treat your first sitting as a full-strength attempt, not a diagnostic. The 30-day spacing and 12-month window mean a retest is workable, but it still costs time and requires you to hold your knowledge steady through the gap. Plan to pass on the first pass, and know your fallback.
Scheduling and window details are covered in our RC exam dates guide.
Where the Credential Gets Used
Registry certification is relevant to the professionals and agencies that perform or oversee death investigation. In practice that means medical examiner offices, coroner offices, and the investigative staff attached to them. Because eligibility requires current qualifying medicolegal-investigation employment, the credential is typically earned by people who are already working in the field rather than by outsiders hoping to break in, so employers often treat it as a marker of professional standing and as support for career advancement.
We deliberately avoid quoting salary or hiring-demand numbers here, because the source material does not supply verified figures and we won't invent them. For a discussion of how certification may factor into pay and advancement, see the RC salary guide, and for the broader value question, is the RC certification worth it. If you are mapping career options, RC jobs collects the roles where this credential comes up.
Keeping the Credential Current
Earning the certification is not the end of the obligations. ABMDI maintains it through recurring requirements:
- A $50 annual fee
- Recertification every five years, with 45 approved continuing education hours
- Ethics compliance
- Employment verification, or, if you are not currently employed in the field, the manual's conditional continued-competency or recertification-examination route
- A $25 recertification administration fee
The policy manual's recertification and fee sections are the authoritative source, and ABMDI's recertification page is the place to confirm current procedures. Build continuing education into your career rhythm from the start rather than scrambling in year five.
Sequencing Your Preparation
Generic study advice is plentiful; what matters for this exam is how you order the domains. Because every section needs to clear its own bar, schedule by risk, not by interest.
Forensic and Medical Knowledge
- Start with the 20% section because science content takes the longest to absorb
- Build terminology and mechanism-of-death fluency before anything else
Scene and Body Documentation
- Cover both 18% sections together; they reinforce each other
- Practice distinguishing observation from interpretation
The Communication Sections and Wrap-Up
- Review Interagency Communication, Communication with Families, Completing the Investigation, and Additional Duties
- Take full-length timed practice sets to rehearse the four-hour pace

Frequently Asked Questions
On this site, RC refers to Registry Certification (basic), offered through the American Board of Medicolegal Death Investigators. "RC" is our shorthand and not an official ABMDI exam code. It is unrelated to other credentials that happen to share the abbreviation.
Both belong to the basic Registry pathway. Associate (A-ABMDI) covers the no-scene or limited-scene route, while Diplomate (D-ABMDI) reflects documented scene experience. Board Certification (F-ABMDI) is a separate advanced track.
The exam has 240 multiple-choice questions, of which 230 are graded and ten are unscored pilot items. You have four hours, with live virtual proctoring through MonitorEDU.
No. Each of the seven sections must meet its own criterion-referenced standard, set with the modified Angoff method. Be skeptical of any source claiming a single raw-score cutoff, and prepare to be competent across every section.
You may retest failed sections up to twice, with at least 30 days between testing dates, inside the 12-month application/testing window. Only the failed sections are retaken. For the broader picture of outcomes, see the RC pass rate discussion, and for the umbrella overview, what RC certification is.
