What This Cheat Sheet Covers (and What It Doesn't)
This page condenses the essentials of the Registry Certification (basic) pathway from the American Board of Medicolegal Death Investigators (ABMDI) into one scannable review. "RC" is the abbreviation used on this site for that Registry pathway, which includes the Associate (A-ABMDI) and Diplomate (D-ABMDI) levels. It is a different track from the advanced Board Certification (F-ABMDI, Fellow), and nothing here describes that advanced practical or case examination.
Use the sheet for final-week review, for orienting yourself before you start, or as a checklist to confirm you haven't missed a rule. If you want the long-form version of any topic, the RC study guide and the complete guide to all seven RC content areas go deeper. When you're ready to test recall under realistic conditions, the RC practice tests are the natural next step.
The Exam at a Glance
| Item | What to Know |
|---|---|
| Format | Multiple choice |
| Total questions | 240 |
| Graded questions | 230 |
| Unscored pilot questions | Ten (indistinguishable from graded items while testing) |
| Time allowed | Four hours |
| Proctoring | Live virtual proctoring through MonitorEDU |
| Blueprint structure | Seven weighted domains, effective January 1, 2024 |
| Passing method | Criterion-referenced, section by section (modified Angoff standard setting) |
Two practical implications follow. First, because the ten pilot questions look identical to scored ones, you should treat every question as if it counts, and a strange or unfamiliar item is not a sign you are failing. Second, four hours for 240 questions averages out to about one minute per item, which rewards steady pacing over agonizing on any single scenario. For a realistic read on the difficulty side of this, see how hard the RC exam is.
Seven Domains, Weighted
| Domain | Name | 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% |
The weights sum to 100%. Scene Response and Documentation and Body Assessment and Documentation together carry 36% of the exam, which makes the field-practice core of the job the largest block. Forensic and Medical Knowledge is the single biggest domain at 20%.
Here is the catch that raw weights hide: because each section has its own passing standard, a small domain is not a safe place to skip. A 10% domain still has to be passed on its own terms. Weight tells you where to spend extra hours, not where you can afford to be weak.
Domain-by-Domain Must-Know Facts
The blueprint headings tell you what the exam is organized around. The points below translate each heading into the kind of competence you should be able to demonstrate, anchored to the Fundamental Tasks of Medicolegal Death Investigation (the competency document ABMDI references, which prints revision 23.8.24 despite its 2024 filename).
Domain 1: Interagency Communication (10%)
Medicolegal death investigation is a coordination job. Expect scenarios about who needs to be notified, what information flows between agencies, and how to keep roles distinct.
- Know the typical partners: law enforcement, medical examiner or coroner offices, health care facilities, and other responding agencies
- Understand what information is appropriate to share, with whom, and when
- Practice recognizing jurisdictional boundaries and handoffs
Domain 2: Communication with Families (10%)
This domain tests professionalism and sensitivity in some of the hardest conversations in the field.
- Death notification principles: clarity, compassion, and avoiding speculation about cause or manner before it is determined
- Explaining the investigative process, and what families can and cannot expect
- Handling questions about the decedent's property, next steps, and release procedures appropriately
Domain 3: Scene Response and Documentation (18%)
One of the two heavyweight practice domains. Questions revolve around what you do, in what order, and how you record it.
- Scene safety, scene control, and preserving evidence integrity
- Systematic scene observation and written, photographic, and diagrammatic documentation
- Identifying and collecting relevant circumstances, medications, and information sources
- Chain-of-custody awareness for items and evidence
Domain 4: Body Assessment and Documentation (18%)
Tied with scene work in weight. You are expected to observe, describe, and record findings accurately and neutrally.
- External examination vocabulary and consistent description of injuries and conditions
- Postmortem changes and what they can and cannot tell you
- Identification procedures and documentation of clothing, personal effects, and markings
- Distinguishing observation from interpretation in your notes
Domain 5: Completing the Investigation (14%)
The case does not end at the scene. This domain covers gathering and organizing what is needed to close it.
- Collecting medical history, records, and corroborating information
- Preparing complete, defensible reports and case files
- Understanding how your documentation supports the certifier's determinations
Domain 6: Additional Medicolegal Death Investigator Duties (10%)
The catch-all for responsibilities beyond the core scene-and-body workflow.
- Professional conduct, ethics, and role boundaries
- Testimony readiness and working within legal processes
- Related duties your office or jurisdiction may assign, handled within your scope
Domain 7: Forensic and Medical Knowledge (20%)
The largest domain and the one where memorization pays off most.
- Anatomy and physiology fundamentals relevant to death investigation
- Common natural disease processes that cause sudden death
- Mechanisms of injury and the terminology used to describe them
- Foundational forensic concepts: manner and cause distinctions, toxicology awareness, and postmortem processes
Key Takeaway
Domains 3, 4, and 7 together make up 56% of the exam. If your time is limited, make sure those three are solid, then use the remaining time to ensure none of the smaller domains is a weak point, since each needs to be passed separately.
How Passing Works: Section Standards, Not One Percentage
The most common cheat-sheet mistake is writing down a single "magic number" to hit. ABMDI does not use one. Passing is criterion-referenced: each section has its own standard, set through a modified Angoff process in which subject-matter experts judge how a minimally competent investigator would perform on each item. To pass the exam, you must meet the standard in every section.
What that means for you:
- A strong score in Forensic and Medical Knowledge cannot compensate for falling short in Interagency Communication.
- Any advertised "you need X% overall" figure should be treated skeptically. Don't build a study plan around one.
- Your preparation goal is balanced competence across all seven domains, with extra depth where the weights are highest.

Eligibility Snapshot: Points, Not Just Hours
Eligibility is built around a points system rather than a simple years-of-experience count. The essentials:
- Minimum age of 18
- High school graduation or equivalent
- Current qualifying medicolegal-investigation employment
- 640 eligibility points accumulated within five years, including at least 384 employment points
- A professional reference, employer verification, and a trainer-verified Fundamental Tasks competency attestation
The Diplomate Scene-Experience Wrinkle
The Diplomate (D-ABMDI) level carries a scene-experience requirement of 100, but the sources disagree on the unit. The application guide states 100 documented scene hours, while the policy manual's eligibility table states 100 scene points, and the manual retains hours wording elsewhere. These are not equivalent measures. If you are targeting Diplomate, confirm the current expectation directly with ABMDI rather than assuming one reading. The Associate (A-ABMDI) level covers the corresponding no-scene or limited-scene route.
The full qualification walkthrough lives in RC requirements: eligibility, prerequisites, and how to qualify.
Fees, Retests, and Timing
| Item | Detail |
|---|---|
| Application fee | $50 |
| Examination fee | $400, including proctoring |
| Initial outlay | $450 combined, per the fee schedule in the policy manual |
| Retesting | Failed sections may be retested twice |
| Retest spacing | At least 30 days between testing dates |
| Retest window | Within the 12-month application and testing window |
| Retest scope | Only the sections you failed |
The retest structure is more forgiving than a full-exam retake: you are not asked to repeat sections you already passed. But the 30-day spacing and 12-month window mean a failed attempt should trigger a targeted plan quickly. Review your section-level feedback, identify the weak domain, and schedule with the clock in mind. Scheduling specifics are covered in RC exam dates, testing windows, and deadlines, and the broader financial picture is in the RC certification cost breakdown.
Keeping the Credential: Maintenance Cheat Sheet
Earning the credential is the first milestone; maintaining it is ongoing. The recurring requirements are:
- Annual fee: $50 per year
- Recertification cycle: every five years
- Continuing education: 45 approved hours within the cycle
- Ethics compliance throughout
- Employment verification, or, if you are not currently employed, the manual's conditional continued-competency or recertification-examination route
- Recertification administration fee: $25
The practical takeaway is to log continuing education as you go rather than reconstructing five years of training at the deadline. If you are weighing whether the ongoing commitment is worth it, see whether the RC certification is worth it.
Sequencing Your Review by Weight
You do not need a generic study system here; you need an order that matches the blueprint. One sensible way to sequence a focused review, based on weight and on how the domains build on each other:
Forensic and Medical Knowledge (20%)
- Start with the largest domain; its terminology supports every other section
- Build a running glossary of anatomy, disease, and injury terms
Scene Response and Documentation (18%)
- Work through scene sequence, safety, evidence handling, and documentation methods
Body Assessment and Documentation (18%)
- Practice describing findings neutrally and linking them to postmortem changes
Completing the Investigation (14%) plus the three 10% domains
- Cover case closure, reporting, interagency coordination, family communication, and additional duties
- Finish with timed mixed practice across all seven domains
Because every section carries its own passing standard, spend the final stretch on whichever domain your practice results show as weakest, regardless of its weight. For more structure, the RC study guide lays out a fuller preparation approach, and timed sets on the practice test site help you check your pace against the roughly one-minute-per-question budget.
Frequently Asked Questions
There are 240 multiple-choice questions, but only 230 are graded. Ten are unscored pilot questions that cannot be told apart from scored ones, so answer every item as though it counts.
No. Passing is criterion-referenced and applied section by section, with standards set using a modified Angoff process. You must meet the standard in each section, so a single overall percentage is not the right target.
The fee schedule lists a $50 application fee and a $400 examination fee that includes proctoring, for $450 combined at the start. Annual maintenance fees and a recertification administration fee apply later.
No. Only failed sections are retested. You may retest twice, with at least 30 days between testing dates, inside the 12-month application and testing window.
No. It is 640 eligibility points earned within five years, including at least 384 employment points. Points and hours are different units and should not be treated as interchangeable.
