- The Registry exam has no single advertised raw percentage; each of the seven sections must meet its own passing standard.
- Standards are criterion-referenced and set through modified Angoff standard setting, not by curving against other candidates.
- The exam has 240 multiple-choice questions: 230 graded plus ten unscored pilot questions, in four hours.
- Failed sections can be retested twice, at least 30 days apart, within the 12-month window; only failed sections are retaken.
Why There Is No Single Passing Percentage
Candidates searching for the "RC passing score" usually want one number: 70%, 75%, or some other cutoff to aim for. For Registry Certification (basic) from the American Board of Medicolegal Death Investigators (ABMDI), that number does not exist in the way most people expect. The credential is built on section-level, criterion-referenced standards, and the governing documents do not substitute a single advertised raw percentage for them.
That distinction changes how you should prepare. If you believed a blended score of, say, three-quarters correct would carry you, you might lean on your strongest area and coast through a weaker one. The Registry structure punishes that approach. Each of the seven weighted sections must be passed on its own terms, so a stellar result in one area does not rescue a shortfall in another.
This article draws on ABMDI's Policy and Procedure Manual (June 2024, revision 24.5.31, Appendix C) and the Registry Certification Application Process document (revision 24.6.1). Where those sources leave a detail unpublished, we say so rather than guess.
The Exam You Are Actually Sitting
Understanding the scoring starts with understanding the instrument. The Registry examination consists of:
- 240 multiple-choice questions in total
- 230 graded questions that count toward your section results
- Ten unscored pilot questions mixed in, used to evaluate future items
- Four hours of testing time
- Live virtual proctoring through MonitorEDU
You will not know which ten questions are the unscored pilots. That is deliberate and it has a practical consequence: treat every question as if it counts. Do not burn extra minutes agonizing over a question that happens to be a pilot item, and do not assume a strange-looking question is "probably unscored" and guess carelessly.
Four hours for 240 questions averages out to roughly one minute per item. That pace is comfortable for knowledge recall questions but tight for scenario-based items that ask you to weigh scene findings, documentation requirements, or family-communication choices. Practicing at pace matters, and our practice tests are a good way to build that rhythm before test day.
How the Seven Sections Are Scored
The current seven-section structure took effect January 1, 2024, replacing older eight-section descriptions you may still find in outdated study materials. If a guide you own lists eight sections, it predates the current blueprint. Our RC Exam Domains 2026: Complete Guide to All 7 Content Areas walks through each one in detail.
Each section has its own criterion-referenced passing standard. In practical terms:
- Your answers are sorted into the seven content sections.
- Your performance in each section is compared against that section's standard, not against other candidates.
- To earn the credential, you must meet the standard in every section.
"Criterion-referenced" is the key phrase. Your result does not depend on how well anyone else tested that day, and there is no curve. If everyone in your testing window is well prepared, everyone can pass. If the group struggles, no quota rescues anyone.
Key Takeaway
Think of the exam as seven small gates rather than one big wall. Your preparation goal is not "reach an overall percentage" but "clear the standard in each of the seven sections." Weak-spot identification matters more here than for a blended-score exam.
What Modified Angoff Means for Your Preparation
The passing standards are established using a modified Angoff standard-setting process. You do not need to be a psychometrician, but knowing the logic helps you study smarter.
In an Angoff-style process, a panel of subject-matter experts reviews each question and judges how a minimally competent practitioner would perform on it. Those judgments are aggregated into the passing standard for the content area. The result is a bar tied to job competence rather than an arbitrary round number.
What this implies for candidates
- The bar reflects minimum competence, not perfection. You are being measured against what a capable, working investigator should know, not against a theoretical expert.
- Easier items tend to carry higher expectations. Foundational questions on documentation basics and communication norms are the kind a minimally competent investigator should answer correctly, so missing them hurts.
- Standards can differ by section. Because each section is evaluated separately, you should not assume the same raw proportion correct is needed everywhere.

Section Weights and What Each Standard Demands
Weights tell you how many of the graded questions come from each area. They do not change the fact that every section needs its own pass. Here is how the blueprint breaks down:
| Section | Weight | Why a weak result here is costly |
|---|---|---|
| Interagency Communication | 10% | Fewer questions means each miss moves your section result noticeably |
| Communication with Families | 10% | Judgment-based items; plausible-sounding wrong answers are common |
| Scene Response and Documentation | 18% | Large share of the exam; procedural precision is tested |
| Body Assessment and Documentation | 18% | Large share; detailed observation and recording standards |
| Completing the Investigation | 14% | Ties together findings, records, and case closure duties |
| Additional Medicolegal Death Investigator Duties | 10% | Broad scope; easy to under-study |
| Forensic and Medical Knowledge | 20% | Largest section; deepest technical content |
The low-weight trap
The three 10% sections, Interagency Communication, Communication with Families, and Additional Medicolegal Death Investigator Duties, are the ones candidates most often under-prepare. They look "soft" or miscellaneous next to the 18% and 20% sections. But with a smaller pool of questions, a handful of misses can sink the section outright, and failing any one section means retesting it.
Forensic and Medical Knowledge (20%)
The largest single section and the one most likely to separate prepared from unprepared candidates. Expect questions that require applying medical and forensic concepts to realistic investigative situations rather than reciting definitions.
- Prioritize understanding over memorization of isolated terms
- Practice reading a scenario and identifying which findings are significant
- Review the content outline in the Fundamental Tasks document alongside the blueprint
Scene Response and Documentation (18%) and Body Assessment and Documentation (18%)
Together these two sections account for more than a third of the exam. Both reward procedural fluency: knowing what to observe, in what order, and how to record it accurately.
- Know documentation expectations cold, since questions often hinge on what belongs in the record
- Practice distinguishing observation from interpretation
- Connect each task to why it matters for the investigation
Communication with Families (10%)
Often the most judgment-heavy section. The best answer typically balances compassion, accuracy, and professional boundaries.
- Expect multiple answers that sound reasonable; look for the one that best fits professional standards
- Know what information is appropriate to share and what is not

Failed a Section? How Retesting Works
Because passing is evaluated section by section, the retest rules are more forgiving than a retake-everything model. Per the application process documentation:
- A failed section may be retested up to two times.
- There must be at least 30 days between testing dates.
- All attempts must fall within the 12-month application/testing window.
- Only the failed sections are retested; sections you passed are not repeated.
This structure rewards diagnosis. If your first attempt leaves you short in a single section, you can focus intensively on that content rather than re-studying everything. It also makes the 30-day minimum an opportunity: use the gap for targeted remediation, not a vague "study more" plan.
Eligibility and Fees That Come Before the Score
You cannot sit the exam until your application is approved, so the "score" conversation really begins with eligibility. The Registry pathway uses a points system rather than a flat hours requirement.
Core eligibility elements
- 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
- A trainer-verified Fundamental Tasks competency attestation
Note that the 640 figure is in points. It should not be read as a universal 640-hour requirement. Full detail is in RC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Associate versus Diplomate
The basic Registry pathway includes Associate (A-ABMDI) and Diplomate (D-ABMDI) levels, distinct from the advanced Board Certification/Fellow (F-ABMDI). The Associate route covers investigators with no or limited scene experience. The Diplomate level carries a scene-experience requirement, and here the sources disagree on units: the application guide states 100 documented scene hours, while the manual's eligibility table states 100 scene points. These are not equivalent, so confirm the current requirement directly with ABMDI before you apply.
Fees
| Item | Amount |
|---|---|
| Application fee | $50 |
| Examination fee (includes proctoring) | $400 |

Sequencing Your Prep Around Section Standards
Because every section needs its own pass, an effective plan front-loads the sections where a miss is most likely and keeps the small sections from being forgotten. One sensible sequencing, tied to the blueprint:
Forensic and Medical Knowledge
- Start with the heaviest, most technical section while energy is high
- Build vocabulary and concept links you will reuse in scene and body assessment
Scene Response and Body Assessment (with documentation)
- Study the two 18% sections together since their content overlaps
- Drill documentation conventions until they are automatic
Completing the Investigation
- Connect findings, records, and closure duties into one workflow
The three 10% sections
- Interagency Communication, Communication with Families, and Additional Duties
- Give each dedicated time so none is a casual afterthought
Timed mixed review
- Run full-length timed sets at roughly one minute per question
- Tally misses by section, not just overall, and revisit your weakest
The final-week tallying step is the one that matters most for this exam. Track your practice results per section. An overall score hides exactly the weakness that would cost you a section.
After You Pass: Maintaining the Credential
Passing every section earns the credential, but it is not permanent without upkeep. Maintenance includes:
- A $50 annual fee
- Five-year recertification requiring 45 approved continuing education hours
- Ethics compliance
- Employment verification, or the manual's conditional continued-competency/recertification-examination route when not currently employed
- A $25 recertification administration fee
Whether that ongoing commitment is worthwhile depends on your career path. Our Is the RC Certification Worth It? Complete ROI Analysis 2026 and RC Salary Guide 2026: Complete Earnings Analysis can help you weigh it, and RC Jobs covers the kinds of roles where the credential carries weight.
This Registry level does not include the advanced Board Certification practical/case examination; that belongs to a separate, higher credential.
Frequently Asked Questions
No. The Registry exam uses a separate criterion-referenced passing standard for each of its seven sections, established through modified Angoff standard setting. The official materials do not substitute one advertised raw percentage, so be wary of sources that claim one.
There are 240 multiple-choice questions, of which 230 are graded and ten are unscored pilot questions. You cannot tell which are pilots, so answer every question as if it counts. You have four hours under live virtual proctoring through MonitorEDU.
No. Each section must meet its own standard. Although Forensic and Medical Knowledge is the largest at 20%, a shortfall in any other section still means that section must be retested.
You may retest each failed section up to two times, with at least 30 days between testing dates, all within the 12-month application/testing window. Only the failed sections are retaken; sections you already passed are not repeated.
The primary sources are ABMDI's Policy and Procedure Manual (June 2024, revision 24.5.31, Appendix C) and the Registry Certification Application Process document (revision 24.6.1). Because details can be updated, verify current requirements directly with ABMDI before applying. For a broader introduction, start with What Is RC Certification?
Approach the Registry exam as seven competencies to demonstrate rather than one number to hit, track your readiness section by section, and use timed practice questions to find gaps while there is still time to close them.
