MGP Certification

What MGP Certification Actually Is

Certification in Pathology: Molecular Genetic Pathology (MGP) is a jointly sponsored subspecialty credential administered by the American Board of Pathology (ABPath) in coordination with the American Board of Medical Genetics and Genomics (ABMGG). It recognizes physicians who can interpret molecular laboratory data, sequence and array findings, and cytogenetic material within a clinical diagnostic context spanning inherited disease, oncology, hematopathology, and infectious disease. This site focuses specifically on the initial physician MGP examination administered through ABPath - not the separate Laboratory Genetics and Genomics certification track, and not any other credential that happens to share the "MGP" acronym.

If you're still orienting yourself to the basics, our companion pieces on What Is MGP?, MGP Meaning, and What Does MGP Stand For? walk through the terminology before you dive into exam mechanics.

Eligibility and Pathway Into the Exam

Candidates must hold qualifying primary ABPath certification in AP/CP, AP alone, or CP alone, or hold eligible ABMGG physician certification. On top of that primary credential, candidates need 12 months of ACGME-accredited Molecular Genetic Pathology fellowship training, plus the applicable medical education, licensure, and training-verification requirements ABPath specifies for subspecialty applicants.

This is not an exam you sit for casually alongside general board prep - it presumes a completed residency, a primary certification already in hand, and a full year of focused fellowship training in molecular genetic pathology. For a full breakdown of every prerequisite, see MGP Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Fees, Registration, and Test-Day Logistics

For the 2026 cycle, the ABPath application/examination fee for initial MGP certification is USD 2,100. That figure includes a USD 200 nonrefundable administrative fee, which is assessed regardless of whether you ultimately sit for the exam. Budget for this early, since the administrative portion is not recoverable if plans change.

Testing is conducted in person at Pearson VUE Professional Centers. There is no remote-proctoring option for this examination - candidates need to plan travel, scheduling, and identification requirements around an in-person test center appointment rather than a home-based setup.

Scheduling windows, application deadlines, and testing dates are covered in detail in MGP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.

Exam Format: 245 Questions, Six Sections

The MGP examination is computer-based and uses single-best-answer multiple-choice items, including written and practical material that asks candidates to interpret data rather than simply recall facts. For the 2026 administration, the exam contains 245 questions organized across six sections.

Active testing time totals 6 hours 34 minutes. When you add instructions, a survey, and scheduled breaks, the total time you should plan to be at the test center is 9 hours 4 minutes. This is a full-day commitment, and candidates should plan travel and rest accordingly rather than trying to schedule anything else around exam day.

Because the question style leans heavily on interpreting sequence traces, array reports, karyotypes, and pedigrees rather than pure definitional recall, practicing with realistic item formats matters more than memorizing lists. Our MGP Study Guide 2026: How to Pass on Your First Attempt breaks down how to train for this interpretation-heavy format, and How Hard Is the MGP Exam? Complete Difficulty Guide 2026 discusses what makes the exam demanding beyond raw content volume.

The 17 Domains You Need to Master

ABPath's 2026 blueprint organizes MGP content into 17 domains with approximate percentage allocations. Solid Tumors is the single largest domain at 11%, followed by Inherited Diseases at 10% and Hematopathology at 9%. The remaining domains each carry smaller individual weights but collectively make up more than half the exam, so no domain can be safely ignored.

The remaining 14 domains - Normal Structure and Function (7%), Molecular Genetic Principles (7%), Assay Performance and Validation (7%), Techniques and Methods (5%), Quality (6%), Ethical, Legal, and Regulatory issues (5%), Indications for testing (4%), Inherited Cancer Syndromes (5%), Pharmacogenetics (5%), Infectious Disease (6%), Identity Testing (4%), Histocompatibility (2%), Informatics (4%), and Management and Informatics-General (3%) - round out a blueprint that spans laboratory methodology, regulatory compliance, and clinical application in roughly equal measure to disease-specific content.

A recurring theme across domains is the need to distinguish germline from somatic findings, and to separate infectious-disease molecular testing from laboratory-method questions about the assays themselves. For a domain-by-domain walkthrough with study priorities for each, see MGP Exam Domains 2026: Complete Guide to All 17 Content Areas.

Passing Standard and What the 2025 Numbers Show

ABPath sets the MGP passing standard as a scaled score of 500 - not a fixed raw percentage of correct answers. This means the number of questions you need to answer correctly can shift slightly between administrations depending on item difficulty, but the target scaled score itself does not change. Details on how the scaled score is derived and what it means for your study targets are covered in MGP Passing Score 2026: Exactly What You Need to Pass.

In 2025, ABPath reported that 50 of 56 total examinees passed the MGP exam, a result reported as 89%. Among first-time examinees specifically, 45 of 49 passed, reported as 92%. These figures reflect a small, highly self-selected candidate pool of physicians who have already completed primary board certification and a full fellowship year - a very different context from open-enrollment exams. A deeper analysis of these numbers, including how first-time versus repeat performance compares, is available in MGP Pass Rate 2026: What the Data Shows.

Building an MGP-Specific Study Plan

Generic study techniques - spaced repetition, timed practice blocks, active recall - only help if you're applying them to the right material in the right order. Given that Solid Tumors, Inherited Diseases, and Hematopathology together account for 30% of the blueprint, a sensible study sequence front-loads those three domains before moving to the assay-methodology and regulatory domains.

Whatever schedule you build, run practice questions under conditions that mirror the actual six-section, 245-question structure so your pacing instincts match test day. You can start building that habit now on our MGP practice test platform, which mirrors the domain distribution described above.

Who Hires MGP-Certified Pathologists

MGP-certified physicians typically work in academic medical center molecular diagnostics laboratories, reference laboratories running large-scale genomic testing menus, cancer center molecular tumor boards, and hospital systems building or overseeing in-house molecular pathology services. The credential signals competency across the full range of molecular testing - inherited disease, solid tumor genomics, hematologic malignancy, pharmacogenetics, and infectious disease - which is precisely the breadth many laboratory director and medical director roles require.

Maintaining Certification After You Pass

Current ABPath certificates do not carry a fixed expiration date, but holding one is conditional on ongoing participation in Continuing Certification. This includes biennial PATHway reporting, maintaining professional standing, and demonstrating lifelong learning and improvement in medical practice.

The standard continuing medical education route requires 70 qualifying credits per two-year reporting period, with at least 80% of those credits related to your scope of practice. Approved training and research alternatives also exist for diplomates whose activity doesn't fit the standard CME model. In addition, ABPath CertLink offers a quarterly assessment format, with a cumulative performance requirement of at least 60% measured over a four-year period. Note that these continuing-certification requirements apply specifically to ABPath diplomates; ABMGG diplomates follow their own issuing board's maintenance requirements.
