What Is A FP?

What Does FP Actually Mean?

FP stands for Certification in Pathology: Forensic Pathology, the initial subspecialty credential issued by the American Board of Pathology (ABPath). It's the formal recognition that a physician who has already completed primary certification in Anatomic Pathology/Clinical Pathology (AP/CP) or Anatomic Pathology (AP) has also completed accredited fellowship training and demonstrated competency in the medical and legal investigation of death.

Because "FP" is used as shorthand across several unrelated fields, it's worth being precise: on this site, FP always refers to the ABPath forensic pathology subspecialty exam described in this article - not any other credential that happens to share the same two letters. If you landed here after searching What Is FP?, FP Meaning, or What Does FP Stand For?, this is the same certification, just approached from a different angle.

Who Administers the FP Credential?

ABPath is the sole certifying body for FP. It sets the eligibility rules, writes and scores the exam, publishes the content specification, and governs the continuing certification requirements that keep a diplomate's certificate active. There is no other route to earning the FP designation - no alternate registry, no third-party exam vendor sets the standards, though the actual test-day administration happens through Pearson VUE Professional Testing Centers.

If you want the full picture of what the credential involves before diving into study materials, the overview pages FP Certification and What Is FP Certification? cover the administrative side in more depth, while this article focuses on what the exam itself demands.

Exam Format: What Sitting for FP Looks Like

FP is a one-day, computer-based examination containing 275 single-best-answer multiple-choice questions, split into two distinct sections:

• Written/Practical: 225 questions, three hours 45 minutes
• Virtual Microscopy: 50 questions, two hours 56 minutes

Total testing time is six hours 41 minutes. The full scheduled exam day, including tutorial, survey, lunch, and other breaks, runs nine hours 11 minutes for the 2026 administration. Microscopic questions are presented as virtual slides rather than physical glass slides, and questions throughout the exam can also incorporate scene photographs, gross photographs, and radiographs - meaning image interpretation isn't confined to the microscopy section alone.

The 54 Domains You're Tested On

ABPath's blueprint organizes FP content into 54 ordered domain lines, each carrying its own approximate weight in the Written/Practical section and, separately, in the Virtual Microscopy section. These are not combined into one whole-exam percentage - a domain can be heavily weighted in one section and absent from the other.

Some domains anchor the exam. Firearm Related Injuries holds the single largest Written/Practical weight at 10%. Blunt Trauma sits at 8% Written/Practical but claims the largest Virtual Microscopy weight at 10%. Other high-value areas include Asphyxia (5% Written/Practical), Transportation Related Deaths (5% Written/Practical), and Mechanical & Physical Injury (3%/2%). Meanwhile, domains like Natural Deaths, Peripheral Nerve and Skeletal Muscle, Bombs and Explosions, and several organ-system topics carry 0% in one or both sections - they're on the blueprint but weighted lightly or folded into other tested content.

Because the 54 domains span everything from Pediatric Deaths and Cardiovascular System to Bioterrorism and Chemical Agents and Postmortem Radiography, treating them as a flat list is a mistake. A domain-by-domain walkthrough with the full weight table is available in FP Exam Domains 2026: Complete Guide to All 54 Content Areas, and it pairs well with the practice questions on the main practice test site when you want to test recall against specific domains rather than study in the abstract.

Eligibility: Who Can Sit for FP?

FP is not an entry-level exam. To sit for it, a candidate must hold primary certification in AP/CP or AP from ABPath, complete 12 months of ACGME-accredited Forensic Pathology fellowship training, hold a qualifying medical degree, and provide training verification. A full, unrestricted medical license is required for certification to be issued. In short, this is a post-residency, post-fellowship credential aimed squarely at physicians who have already committed to a forensic pathology career path.

A full walkthrough of documentation requirements, timelines for submitting fellowship verification, and common eligibility pitfalls is covered in FP Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Registration, Fees, and Testing Windows

The 2026 FP examination fee is $2,100, which includes a $200 nonrefundable administrative fee. Testing occurs at Pearson VUE Professional Testing Centers during a defined annual window - for 2026, that window runs September 8-28. Because this is a single annual testing period rather than a rolling, on-demand exam, missing the registration deadline generally means waiting a full year for the next opportunity.

Passing Score and Pass Rates

FP uses a criterion-referenced passing scaled score of 500 - there is no fixed raw percentage of correct answers that guarantees a pass, since the scoring accounts for question difficulty across administrations. In 2025, the overall pass rate was 78% (52 of 67 candidates), with first-time takers passing at 79% (46 of 58) and repeat takers at 67% (6 of 9).

For the full context behind these numbers, including how they compare across recent cycles, see FP Pass Rate 2026: What the Data Shows. And if you want the mechanics of exactly how the scaled score works, FP Passing Score 2026: Exactly What You Need to Pass unpacks it further.

Keeping the Certificate After You Pass

An FP certificate has no fixed expiration date, but it remains active only through participation in ABPath's Continuing Certification program. The standard route requires 70 CME credits per two-year reporting cycle, with at least 80% of those credits relevant to the diplomate's scope of practice. At least two improvement-in-practice or quality-assurance activities are required per two-year cycle, alongside standard licensure and professionalism requirements.

ABPath also uses CertLink, a longitudinal assessment tool that assigns 10-15 questions per quarter. Diplomates must complete assigned questions and maintain at least 60% cumulative correctness across the four-year assessment period. These maintenance requirements are entirely separate from the initial certification exam's passing score - passing FP once does not satisfy ongoing CertLink obligations.

Who Hires FP-Certified Pathologists?

FP-certified physicians typically work in medical examiner and coroner offices, performing forensic autopsies, testifying in court, and consulting on cause and manner of death. Others hold academic appointments where they combine casework with training the next generation of fellows, or work within larger pathology groups that provide contracted forensic services to counties or regions. Because certification confirms both AP/CP or AP foundations and specialized fellowship training, it functions as a baseline credential for many forensic pathologist positions rather than an optional add-on.

Sequencing Your Study Around the Blueprint

Because Written/Practical and Virtual Microscopy weights diverge by domain, an efficient study sequence treats them as two overlapping tracks rather than one linear pass through material. High-weight, dual-relevance domains like Blunt Trauma and Mechanical & Physical Injury deserve early, repeated attention since they pay off in both exam sections. Domains that are heavy in one section only - Firearm Related Injuries in Written/Practical, or organ-system topics that skew toward Virtual Microscopy - can be scheduled more narrowly, with study time matched to the section where they actually appear.

A more granular week-by-week plan, including how to rotate practice questions by domain weight, is in FP Study Guide 2026: How to Pass on Your First Attempt. When you're ready to test retention under realistic timing, practice questions modeled on the FP blueprint can help confirm which domains still need attention before you commit to a September testing window.
