What Does FP Mean?
FP is the official abbreviation for Certification in Pathology: Forensic Pathology, a physician subspecialty credential awarded by the American Board of Pathology (ABPath). It is not a general wellness or family-practice designation - FP here refers specifically to board certification for pathologists who investigate deaths for legal and public-health purposes, performing autopsies, interpreting injury patterns, and testifying in court about cause and manner of death.
Because FP overlaps with acronyms used by other unrelated credentials, it's worth being precise from the start: on this site, and throughout this article, FP means only the ABPath forensic pathology subspecialty exam. If you landed here researching a different "FP," this page - and the rest of What Is FP? - will not apply to that credential.
Who Certifies FP and Why It Matters
The American Board of Pathology is the sole certifying body for FP. This matters because ABPath sets the eligibility rules, writes the content specification, schedules the exam windows, and determines the passing standard. Anyone claiming FP status without having sat the ABPath exam is not board-certified in forensic pathology in the sense this credential defines.
Employers - medical examiner offices, coroner systems, university forensic pathology departments, and some private forensic consulting groups - typically list ABPath FP certification (or active pursuit of it) as a hiring or credentialing requirement. If you're evaluating career paths, FP Jobs covers the kinds of positions that expect this credential, and FP Salary Guide 2026: Complete Earnings Analysis looks at compensation considerations tied to holding it.
Exam Format: What "FP" Looks Like on Test Day
The FP exam is a one-day, computer-based test delivered at Pearson VUE Professional Testing Centers. It consists of 275 single-best-answer multiple-choice questions split into two distinct sections:
- Written/Practical: 225 questions in 3 hours 45 minutes
- Virtual Microscopy: 50 questions in 2 hours 56 minutes
Total testing time is 6 hours 41 minutes. The full scheduled day - including tutorial, survey, lunch, and other breaks - runs 9 hours 11 minutes for the 2026 administration. This is a long, demanding day, and pacing across both sections is a real factor, not just content mastery.
A distinctive feature of FP is that microscopic cases are presented as virtual slides rather than glass slides, and questions throughout the exam may incorporate scene photographs, gross photographs, and radiographs - reflecting the multimodal nature of real forensic casework. For a deeper breakdown of what makes this format challenging, see How Hard Is the FP Exam? Complete Difficulty Guide 2026.
Key Takeaway
Treat Written/Practical and Virtual Microscopy as two separate skill sets to prepare for - image interpretation under virtual-slide conditions is not identical to answering text-based vignettes.
The 54 Domains Behind the FP Acronym
FP's content specification organizes material into 54 domain lines, covering everything from organ-system natural disease to the full range of unnatural death investigation. Weights are published separately for Written/Practical and Virtual Microscopy percentages rather than as one blended distribution, and several domains carry a 0% weight on one section while still appearing as explicit blueprint entries.
Firearm Related Injuries (Domain 24)
This domain carries the single largest Written/Practical weight at 10%. Candidates should be fluent in wound ballistics, range-of-fire determination, and distinguishing entrance from exit wounds.
- Highest Written/Practical weight of all 54 domains
Blunt Trauma (Domain 22)
Weighted 8% Written/Practical and 10% Virtual Microscopy - the largest Virtual Microscopy weight on the entire exam. Expect heavy image-based testing here.
- Largest Virtual Microscopy weight of any domain
Asphyxia (Domain 23)
Weighted 5% Written/Practical with no Virtual Microscopy weight, making it a text/scenario-driven domain focused on mechanism and scene findings.
- 5% Written/Practical, 0% Virtual Microscopy
Transportation Related Deaths (Domain 51)
Weighted 5% Written/Practical, covering pedestrian, occupant, and vehicular injury patterns with no dedicated microscopy weight.
- Tied for second-highest Written/Practical weight
Other heavily weighted areas include Infectious Disease/Microbiology (Domain 16, 2%/8%), Respiratory System (Domain 7, 2%/8%), Chemical Injury including toxicology (Domain 34, 3%/2%), and Sharp Injuries (Domain 26, 3%/0%). Note that the published Written/Practical row values sum to 99% in the source document despite a printed column total of 100%, and Virtual Microscopy values total 100% exactly - this content follows the source values without renormalizing them.
For the complete list of all 54 domain names and every published weight pairing, see the dedicated breakdown at FP Exam Domains 2026: Complete Guide to All 54 Content Areas.
| Domain | Written/Practical % | Virtual Microscopy % |
|---|---|---|
| Firearm Related Injuries (D24) | 10% | 0% |
| Blunt Trauma (D22) | 8% | 10% |
| Asphyxia (D23) | 5% | 0% |
| Transportation Related Deaths (D51) | 5% | 0% |
| Infectious Disease/Microbiology (D16) | 2% | 8% |
| Respiratory System (D7) | 2% | 8% |
Who Can Sit for FP
FP eligibility is not open to any pathologist by default. ABPath requires:
- Prior AP/CP or AP primary certification from ABPath
- 12 months of ACGME-accredited Forensic Pathology fellowship training
- A qualifying medical degree and verified training documentation
- A full, unrestricted medical license for certification
This sequencing means FP is always a second-stage credential - candidates first establish primary board certification, then complete a dedicated forensic fellowship year, before they can register for the FP exam. A full walkthrough of documentation and timing is in FP Requirements 2026: Eligibility, Prerequisites & How to Qualify.
FP Fees and Testing Windows
The 2026 examination fee is $2,100, which includes a $200 nonrefundable administrative fee. Testing takes place at Pearson VUE Professional Testing Centers during the window of September 8-28, 2026. Because this is a defined annual window rather than continuous testing, missing registration deadlines typically means waiting for the next cycle.

FP Is Not the Other "FP"
Because "FP" is used as shorthand by multiple unrelated credentials and professional roles, it's easy to conflate this ABPath subspecialty with something else entirely. It's also worth distinguishing FP from ABMDI medicolegal death-investigator certification - that is a separate, distinct credential track from ABMDI, not an ABPath physician subspecialty. If your search results mention different certifying organizations, different exam fees, or different question counts, you are very likely looking at a different program. Confirm you're reading about ABPath's forensic pathology subspecialty before applying any facts, fees, or dates to your study plan.

Life After Passing: Maintenance of FP Certification
Passing the FP exam does not produce a credential with a fixed expiration date, but it does remain contingent on ongoing ABPath Continuing Certification participation. The standard route requires:
- 70 CME credits per two-year reporting cycle, with at least 80% related to the scope of practice
- At least two improvement-in-practice/quality-assurance activities per two-year cycle
- Ongoing licensure and professionalism requirements
ABPath also uses CertLink, which assigns 10-15 questions quarterly. Diplomates must complete assigned questions and maintain at least 60% correct cumulatively over the four-year assessment period. These maintenance requirements are entirely separate from - and do not affect - the initial passing score on the certification exam itself.
Key Takeaway
Passing FP is not a one-time event: budget ongoing time for CertLink quarterly questions and CME tracking to keep certification active.
Scheduling Study Time Around the FP Blueprint
Generic study techniques only help when mapped to FP's actual weight distribution. Because Firearm Related Injuries (10% Written/Practical) and Blunt Trauma (8%/10%) carry outsized weight, it makes sense to schedule dedicated weeks on mechanical and physical injury topics early, while there's still time to revisit them before test day, rather than treating all 54 domains as equally urgent.
High-Weight Injury Domains
- Firearm Related Injuries, Blunt Trauma, Asphyxia, Sharp Injuries
- Pair Virtual Microscopy practice with Blunt Trauma given its 10% microscopy weight
Organ-System and Infectious Disease Domains
- Respiratory System, Infectious Disease/Microbiology, Cardiovascular System
- Focus microscopy review time here given their combined 8% weights
Lower-Weight but Zero-Overlap Domains
- Domains with explicit 0% entries on one section still require coverage on the other
- Review Transportation Related Deaths, Chemical Injury/Toxicology, and Identification of Human Remains
