PP Pass Rate 2026: What the Data Shows

Understanding the 2025 PP Pass Rate Data

Anyone researching the Certification in Pathology: Pediatric Pathology (PP) subspecialty exam from the American Board of Pathology (ABPath) eventually asks the same question: what percentage of candidates actually pass? The most recent reported data comes from the 2025 administration, where all 17 examinees passed, including all 13 candidates who were sitting for the exam for the first time. Both the overall pass rate and the first-time pass rate were reported at 100%.

That is a genuinely strong result, but it needs context before you build a study strategy around it. This article walks through what the number means, how the exam is structured, where risk tends to concentrate across the blueprint's 23 shared domain headings, and what the registration and eligibility mechanics look like heading into 2026.

Why Small Cohort Size Changes How You Read the Numbers

Pediatric Pathology is a narrow subspecialty relative to primary board certifications, and the 2025 cohort of 17 examinees reflects that. When a pass rate is calculated from a small group, a single additional pass or fail can shift the reported percentage by several points. A 100% pass rate from 17 candidates is a meaningfully different signal than a 100% pass rate from a cohort of several hundred.

This doesn't diminish what the number tells you - it tells you that recent candidates who reached the exam were, on the whole, well prepared and met the scaled passing standard. But it does mean you shouldn't treat "everyone passes PP" as a reason to under-prepare. The candidates in that cohort had already cleared ABPath's eligibility bar: primary certification in AP/CP or AP (or accepted Royal College of Physicians and Surgeons of Canada certification in Anatomic Pathology or General Pathology), plus 12 months of ACGME-accredited Pediatric Pathology fellowship training. Self-selection into a rigorous fellowship pathway likely contributes to strong outcomes at the exam stage.

What the Exam Actually Tests: Two Components, One Certificate

The PP exam is a computer-based multiple-choice examination administered in person at Pearson VUE Professional Centers - it is not remotely proctored, and it is not a glass-slide examination. Instead, the microscopy component is delivered digitally as virtual microscopy questions alongside the written/practical material.

The 2026 schedule breaks down as follows:

The two components run across six total sections, and the full scheduled examination time - including instructions, a survey, and scheduled breaks - is 8 hours 53 minutes. That is a long testing day, and pacing across six discrete sections is its own skill separate from content mastery. If you want a detailed walkthrough of section-by-section format, question style, and how the virtual microscopy interface differs from a written question block, see How Hard Is the PP Exam? Complete Difficulty Guide 2026.

The 23 Domains and Where Pass-Rate Risk Concentrates

The official 2026 blueprint organizes content under 23 shared domain headings, but - and this matters for how you interpret "difficulty" - the written/practical component and the virtual microscopy component are weighted separately. The blueprint intentionally omits a combined percentage so that neither component is misrepresented as a single whole-exam distribution.

The two perinatal domains anchor the written/practical side. Domain 2: Perinatal Pathology: Fetal/Neonatal pathophysiology is the largest single written/practical category at 15%, and Domain 1: Perinatal Pathology: Placental-maternal-fetal relationships in pregnancy sits at 7%. On the virtual microscopy side, each of those two perinatal categories carries 10% - meaning slide-based placental and fetal/neonatal material is proportionally even more prominent under the microscope than on paper.

Beyond perinatal pathology, several organ-system domains carry moderate, fairly balanced weight across both components: Domain 9: Alimentary Tract-GI (7%/8%), Domain 13: Hematopoietic System, including bone marrow, lymph nodes, thymus, spleen and other lymphoid tissues (6%/9%), Domain 10: Hepatobiliary System and Pancreas (6%/8%), and Domain 20: Diagnostic/Technical Procedures (7%/2%). Notice that Domain 20 is weighted much more heavily on the written/practical side than under virtual microscopy - a pattern worth building into your study sequencing.

At the other end, several domains are low-weight on both components - Domain 8 (Special Senses-Eye and Ear), Domain 14 (Breast), Domain 16 (Disorders of Sexual Development), and Domain 17 (Male Reproductive System) each sit at 1-2% in one or both components. And three domains - Domain 21 (Laboratory Management-Pediatric Pathology), Domain 22 (Forensic Pathology), and Domain 23 (Management & Informatics-General) - carry a written/practical weight but no listed virtual microscopy weight at all, since they're administrative or non-slide-based content areas.

A full domain-by-domain breakdown with study guidance for every one of the 23 headings - including the mid-weight systems like Central Nervous System, Respiratory System and Mediastinum, and Kidney and Urinary System - is available in PP Exam Domains 2026: Complete Guide to All 23 Content Areas.

The Passing Standard: Scaled Score, Not Percentage

A common misconception is that PP candidates need to answer a fixed percentage of the 235 questions correctly. That is not how ABPath scores the exam. The passing standard is a scaled score of 500 - a psychometrically adjusted score, not a raw percentage of correct answers. This means the exact number of questions you need to answer correctly can vary slightly by form, since scaling accounts for item difficulty.

Practically, this means you cannot reverse-engineer a "safe" number of misses. The soundest strategy is to prepare broadly across all 23 domains rather than trying to game a percentage threshold. For a deeper explanation of how the scaled scoring model works and what it means for how you should study, see PP Passing Score 2026: Exactly What You Need to Pass.

Registration Mechanics That Affect Your Odds

Pass-rate outcomes don't exist in a vacuum from the administrative process, and a few mechanics are worth knowing before you register:

• Fee structure: The 2026 initial application/examination fee is USD 2,100, which includes a USD 200 nonrefundable administrative fee. Budgeting around this - and understanding what happens if you need to withdraw or reschedule - is worth doing before you commit to a testing date.
• In-person testing only: The exam is administered at Pearson VUE Professional Centers. There is no remote-proctoring option, so travel and test-center logistics are part of your preparation timeline, not an afterthought.
• Eligibility gatekeeping: You need primary certification in AP/CP or AP (or accepted RCPSC certification in Anatomic Pathology or General Pathology) plus 12 months of ACGME-accredited Pediatric Pathology fellowship training, along with standard medical education, licensure, and training-verification requirements.

Building a Study Plan Around the Blueprint Weighting

Generic study advice - spaced repetition, timed blocks, active recall - only becomes useful once it's mapped onto PP's actual weighting. Given that Domain 2 (Fetal/Neonatal pathophysiology) alone carries 15% of the written/practical component and 10% of virtual microscopy, it deserves an early and recurring place in your rotation rather than a single pass late in your timeline.

A more detailed week-by-week plan, including how many practice items to target per domain, is laid out in PP Study Guide 2026: How to Pass on Your First Attempt. You can build and time your own domain-weighted practice blocks using the question sets at PP Exam Prep's practice platform.

Continuing Certification After You Pass

Passing the exam isn't the end of the obligation. Current ABPath certificates carry no fixed expiration date, but they remain conditional on ongoing Continuing Certification participation. That includes biennial PATHway reporting, maintaining professional standing, and demonstrating lifelong learning and improvement in medical practice.

Two specific mechanisms sit underneath that umbrella:

• The standard CME route requires 70 qualifying credits per two-year reporting period, with at least 80% related to your scope of practice. Approved training and research alternatives also exist for candidates who don't follow the standard CME path.
• ABPath CertLink offers a quarterly assessment format, with a cumulative performance requirement of at least 60% averaged over a four-year cycle.

Understanding this before you even sit for the initial exam is useful context for weighing the long-term commitment.
