What Is RC Certification?
On this site, "RC" refers to the Registry Certification (basic) offered by the American Board of Medicolegal Death Investigators (ABMDI). It is the entry-level credential pathway for people who investigate deaths on behalf of medical examiner and coroner offices. If you have seen other credentials that share the same two letters, set them aside: everything below describes the ABMDI Registry pathway only.

What the Registry Credential Actually Is
The ABMDI Registry is a professional certification for medicolegal death investigators, the people who respond to scenes, examine decedents, speak with families, and document findings so that a medical examiner or coroner can determine cause and manner of death. The basic Registry credential verifies that an investigator has both the working experience and the tested knowledge to perform those duties competently.
It is distinct from the advanced Board Certification (Fellow, F-ABMDI), which is a separate and more demanding tier. This article covers only the Registry level. For a broader orientation to the acronym and its usage, you can also see our explainers on what RC is and what RC stands for.
Associate vs. Diplomate Status
The basic Registry pathway produces two designations, and the difference comes down to scene experience rather than the exam itself.
| Feature | Associate (A-ABMDI) | Diplomate (D-ABMDI) |
|---|---|---|
| Intended route | No or limited scene experience | Documented scene experience |
| Scene requirement | Corresponding no/limited-scene route | 100 documented scene units (see note below) |
| Registry exam | Same seven-section blueprint | Same seven-section blueprint |
| Part of the basic pathway | Yes | Yes |
Exam Format: 240 Questions, Four Hours, Live Proctoring
The Registry examination is a single sitting with a defined structure:
- 240 multiple-choice questions in total.
- 230 graded questions and ten unscored pilot questions. Pilot items are indistinguishable from graded ones, so treat every question as if it counts.
- Four hours to complete the exam, which works out to roughly one minute per question with a little time to spare for review.
- Live virtual proctoring through MonitorEDU, meaning you test remotely under observation.
Because the questions are multiple-choice, the skill being tested is applied judgment: recognizing what a scene detail means, what the correct documentation step is, or which agency or family communication approach fits a situation. To gauge the challenge, read how hard the RC exam is.
The Seven Exam Domains in Detail
The current seven-section structure took effect January 1, 2024 and replaces older eight-section descriptions. If you find study materials that describe eight sections, they are outdated. The official source is Appendix C of the ABMDI Policy and Procedure Manual (June 2024, revision 24.5.31). For a deeper walkthrough, see our complete guide to all seven content areas.
| Domain | Weight |
|---|---|
| 1. Interagency Communication | 10% |
| 2. Communication with Families | 10% |
| 3. Scene Response and Documentation | 18% |
| 4. Body Assessment and Documentation | 18% |
| 5. Completing the Investigation | 14% |
| 6. Additional Medicolegal Death Investigator Duties | 10% |
| 7. Forensic and Medical Knowledge | 20% |
Domain 7: Forensic and Medical Knowledge (20%)
The largest section. Expect questions that test whether you understand the medical and forensic concepts underlying a death investigation, not just procedure.
- Recognizing findings relevant to cause and manner of death
- Applying medical terminology and basic pathophysiology to case facts
- Understanding how forensic evidence relates to investigative conclusions
Domain 3: Scene Response and Documentation (18%)
Tests how an investigator approaches, secures, and records a death scene.
- Scene safety, evidence preservation, and scene documentation practices
- Recording observations accurately and in a defensible sequence
- Recognizing what must be documented before anything is moved or altered
Domain 4: Body Assessment and Documentation (18%)
Focuses on the examination and documentation of the decedent.
- Describing external findings, injuries, and identifying characteristics
- Documenting the condition and position of the body consistently
- Connecting body findings to the broader investigation
Domain 5: Completing the Investigation (14%)
Covers the work that follows the scene: gathering records, finalizing documentation, and closing out the case file in a way that supports the certifier's determination.
Domains 1, 2, and 6 (10% each)
Interagency Communication addresses coordination with law enforcement, medical facilities, and other agencies. Communication with Families covers delivering information and handling bereaved relatives with professionalism and sensitivity. Additional Medicolegal Death Investigator Duties captures responsibilities that fall outside the core scene-to-closure workflow.
The competency foundation behind these areas is ABMDI's Fundamental Tasks of Medicolegal Death Investigation document. Note that although the file name references 2024, the document itself prints revision 23.8.24.
Eligibility and the Points System
Registry eligibility is not a simple years-of-experience rule. It is built on an accumulated points model, and the points are not a universal 640-hour requirement. The core requirements are:
- Minimum age of 18
- High school graduation or equivalent
- Current employment in a qualifying medicolegal-investigation role
- 640 eligibility points accumulated within five years, including at least 384 employment points
- A professional reference
- Employer verification
- A trainer-verified attestation of competency in the Fundamental Tasks
Because points come from more than one category, two candidates with similar job titles can have different eligibility pictures. Review the full breakdown in our RC requirements article and confirm your count against the current ABMDI manual before you apply.
Application Steps, Fees, and Retesting
The process is documented in ABMDI's Registry Certification Application Process (revision 24.6.1) and the fee schedule in the policy manual.
- Submit the application with supporting verifications.
- Pay the fees: a $50 application fee and a $400 examination fee, which includes proctoring.
- Sit the proctored exam remotely through MonitorEDU.
- Retest if needed: failed sections can be retested twice, with at least 30 days between testing dates, inside the 12-month application/testing window. Only the failed sections are retested.
How Passing Works
Registry scoring does not use a single advertised raw percentage. Each section must meet its own criterion-referenced passing standard, set using the modified Angoff method, in which subject-matter experts judge how a minimally competent investigator would perform on each item. Two practical consequences follow:
- Strength in one domain cannot fully offset weakness in another, because each section is judged against its own standard.
- Any article that quotes one universal "passing percentage" for the whole exam is simplifying in a way the official structure does not support.

Who Uses This Credential
The Registry credential is aimed at working death investigators, and eligibility itself requires current qualifying employment. In practice that points to the offices that investigate deaths: medical examiner offices, coroner offices, and similar medicolegal agencies. Employers in this field use the credential as a verification of baseline competence, and it can support advancement conversations within an office. Because compensation varies widely by jurisdiction and role, we avoid quoting figures here; see the salary guide and RC jobs overview for context, and the ROI analysis if you are weighing the investment.
Keeping the Credential Active
Certification is not permanent. Maintenance under the policy manual includes:
- $50 annual fees
- Recertification every five years, requiring 45 approved continuing education hours
- Ethics compliance
- Employment verification, or the manual's conditional continued-competency/recertification-examination route if you are not currently employed in the field
- A $25 recertification administration fee
Budget for these ongoing costs when comparing the credential's long-term value.
Sequencing Your Preparation by Domain
Rather than a generic schedule, tie your study order to the blueprint weights. One sensible approach for a six-week window:
Forensic and Medical Knowledge
- Start with the 20% domain because it is the broadest and slowest to absorb
- Build terminology and cause/manner concepts early
Scene and Body Documentation
- Cover Domains 3 and 4 together, since together they represent 36% of the exam
- Practice reasoning through documentation order and detail
Completing the Investigation and Communication
- Review Domain 5, then Domains 1, 2, and 6
Timed Practice and Weak-Section Repair
- Work full-length timed sets on the practice test platform
- Since each section is judged separately, rework your weakest domain first
