The Short Answer: What RC Means on This Site
On rcexam.com, RC stands for Registry Certification (basic). It is the entry-level certification pathway offered by the American Board of Medicolegal Death Investigators (ABMDI) for professionals who investigate deaths on behalf of medical examiner and coroner systems. "RC" is the shorthand this site uses for that Registry pathway; it is not an official exam code printed on ABMDI paperwork.
If you landed here searching for a general definition, you can also browse our related explainers: What Is RC?, RC Meaning, and What Is RC Certification?. This article focuses on the acronym itself, what is behind it, and how the credential is actually structured.
Why the Acronym Causes Confusion
Two-letter acronyms are crowded territory. Many professions use "RC" for their own credentials, and search engines return all of them side by side. That makes it easy for a candidate to read an exam fee, a passing percentage, or a testing date that belongs to an entirely different field and assume it applies to them.
For the Registry pathway, the safest habit is to verify every claim against ABMDI's own documents. The two documents that matter most are the ABMDI Policy and Procedure Manual (June 2024, revision 24.5.31) and the Registry Certification Application Process guide (revision 24.6.1). If a number you read online does not trace back to those sources, treat it with suspicion.
This is also why we avoid quoting a single advertised "passing percentage." As explained later, the Registry exam does not work that way. For the full scoring picture, see our guide to the RC passing score.
Who Issues the Credential
The American Board of Medicolegal Death Investigators 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 bodies, communicating with families and partner agencies, and closing out a case file accurately.
The Registry is the foundation tier. ABMDI also offers advanced Board Certification (the Fellow designation, F-ABMDI), which is a separate credential with its own requirements. The Registry exam described in this article does not include the advanced practical or case examination. When you see "RC" on this site, think of the basic Registry credential only.
For a broader orientation to the credential's purpose and audience, see RC Certification and What Does RC Mean?
Registry Levels: Associate vs. Diplomate
Within the basic Registry pathway there are two designations. Which one applies to you depends largely on your scene experience.
| Designation | Credential Letters | Scene Experience Route |
|---|---|---|
| Associate | A-ABMDI | Corresponding no-scene or limited-scene route |
| Diplomate | D-ABMDI | Documented scene experience requirement |
| Fellow (advanced, not covered here) | F-ABMDI | Separate Board Certification pathway |
Our RC requirements guide goes deeper on prerequisites and how to qualify for each designation.
How the Exam Is Built
The Registry examination is a computer-delivered, multiple-choice test with a tightly defined format:
- 240 total questions, all multiple choice
- 230 graded questions plus ten unscored pilot questions used to evaluate future items (you will not know which are which)
- Four hours of testing time
- Live virtual proctoring through MonitorEDU
How passing works
The Registry exam uses a criterion-referenced standard established through the modified Angoff method, in which subject-matter experts judge how a minimally competent investigator would perform on each item. Crucially, each section must meet its own passing standard. Strength in one domain does not offset a shortfall in another. That makes balanced preparation far more important than it would be on an exam scored as a single blended percentage.
Key Takeaway
Because every section is judged separately, treat your lowest-confidence domain as the one that determines your outcome. Use practice testing to find weak sections early, then rebalance your time rather than polishing areas you already know.

The Seven Content Domains
The current seven-section blueprint took effect on January 1, 2024 and replaced older eight-section descriptions. If you find study material that lists eight sections, it is out of date. The official blueprint appears in Appendix C of the Policy and Procedure Manual. Here is how the weight breaks down:
| 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 heaviest section. It tests the scientific and medical foundation behind the investigator's observations.
- Connecting observed findings to plausible causes and manners of death
- Recognizing patterns of injury and disease relevant to death investigation
- Understanding the medical terminology you will encounter in records and reports
Domains 3 and 4: Scene and Body (18% each)
Together these make up more than a third of the exam and reflect the hands-on core of the job.
- Scene safety, evidence handling, and thorough documentation of the environment
- Systematic external examination and documentation of the body
- Accurate, objective recording of what you observe rather than what you assume
Domain 5: Completing the Investigation (14%)
Closing a case properly is its own skill set.
- Assembling records, identification information, and findings into a coherent case file
- Following through on notifications and required follow-up steps
Domains 1, 2, and 6 (10% each)
Smaller in weight but still individually scored against their own standard.
- Interagency Communication: coordinating with law enforcement, medical examiners, coroners, and other partner agencies
- Communication with Families: delivering information with professionalism and sensitivity
- Additional Duties: the range of responsibilities that fall to investigators beyond the core scene-and-body workflow
Our dedicated RC exam domains guide unpacks each content area in more detail. ABMDI also publishes a competency reference, Fundamental Tasks of Medicolegal Death Investigation (the PDF prints revision 23.8.24 despite its 2024 filename), which underpins the trainer-verified competency attestation required for eligibility.
Eligibility and the Points System
Registry eligibility is not a simple years-of-experience checkbox. Candidates must meet all of the following:
- Minimum age of 18
- High school graduation or equivalent
- Current qualifying employment in medicolegal death investigation
- 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
The Registry page on ABMDI's website is also cited for this points wording, but that dynamic page did not render substantive content when we reviewed it, so the downloadable manual and application PDFs are the reliable references. Walk through the full checklist in RC Requirements: Eligibility, Prerequisites & How to Qualify.
Fees, Retests, and Maintenance
Upfront costs
The policy manual's fee schedule sets a $50 application fee and a $400 examination fee, with proctoring included in the exam fee. For a full breakdown of what else to budget, see RC Certification Cost.
Retesting
The retest rules reward targeted study. If you fail one or more sections, you do not retake the entire exam:
- Only the failed sections are retested
- You may retest twice
- There must be at least 30 days between testing dates
- All attempts must fall within the 12-month application and testing window
Scheduling details are covered in RC Exam Dates: Testing Windows, Deadlines & Scheduling.
Keeping the credential active
| Maintenance Item | Requirement |
|---|---|
| Annual fee | $50 per year |
| Recertification cycle | Every five years |
| Continuing education | 45 approved hours |
| Ethics | Compliance required |
| Employment | Verification, or the manual's conditional continued-competency/recertification-examination route if not currently employed |
| Recertification administration fee | $25 |
The recertification page on ABMDI's website also did not render substantive content during our review, so the manual's recertification and fee sections are the authoritative source.
Who Works With This Credential
Because the Registry requires current qualifying employment, the credential is typically held by people already working in death investigation rather than outsiders trying to break in. The natural employers are medical examiner offices and coroner offices, where investigators respond to deaths, examine scenes and bodies, interview families, and prepare case documentation for the certifying pathologist or elected official.
That employment link shapes the value proposition. For many investigators, certification supports professional credibility in court-adjacent work, standardizes expectations across jurisdictions, and demonstrates verified competency to employers. We examine the financial side in the RC salary guide, the career-side picture in RC Jobs, and the bigger decision in Is the RC Certification Worth It?
Sequencing Your Preparation Around the Blueprint
Because each section carries its own passing standard, your schedule should be organized by domain rather than by generic study hours. One workable sequence for an eight-week plan:
Domain 7 foundation
- Start with Forensic and Medical Knowledge: it is the largest section and its vocabulary supports every other domain
- Build a running glossary of medical and forensic terms
Domains 3 and 4
- Cover Scene Response and Documentation, then Body Assessment and Documentation
- Practice thinking through documentation order and objective description
Domains 5, 1, 2, and 6
- Work through Completing the Investigation, then the communication-focused and additional-duties domains
Section-by-section practice
- Take timed practice sets and score each domain separately
- Spend remaining time on whichever section lags, since weakness in one section cannot be offset by another
For a fuller plan, see the RC study guide, keep the RC cheat sheet handy for last-minute review, and explore RC training options. When you are ready to test yourself against the real format, head to our practice test and work through the full-length questions under timed conditions.
Frequently Asked Questions
On this site, RC stands for Registry Certification (basic), the entry-level certification pathway from the American Board of Medicolegal Death Investigators (ABMDI). It covers Associate (A-ABMDI) and Diplomate (D-ABMDI) status.
No. RC is the abbreviation used on this site to refer to the Registry pathway. ABMDI's official materials refer to the Registry Certification program and its Associate and Diplomate designations rather than an "RC" code.
There are 240 multiple-choice questions: 230 graded and ten unscored pilot questions. You have four hours, and the exam is live-proctored virtually through MonitorEDU.
No. Each section must meet its own criterion-referenced passing standard, set using the modified Angoff method. A strong result in one domain does not compensate for falling short in another.
Only the failed sections are retested. You may retest twice, with at least 30 days between testing dates, all within the 12-month application and testing window.
Understanding what RC stands for is the first step; the real work is mastering the seven domains and meeting each section's standard. Start with the complete RC definition if you want a quick refresher, then build your preparation around the blueprint above.
