- The exam is 120 multiple-choice items (100 scored, 20 unscored) in a 3-hour window.
- Passing requires 71% or higher, scored against a fixed criterion - not a curve.
Overview of the CGRA Exam Blueprint
The Cancer Genetic Risk Assessment (CGRA) credential, administered by the National Consortium of Breast Centers (NCBC), tests candidates across five defined content domains. These domains aren't arbitrary study categories - they come directly from the NCBC's currently linked CGRA Exam Description v2 (uploaded July 2023), which governs how the 100 scored questions are distributed across the exam's 120 total multiple-choice items (100 scored, 20 unscored, 3-hour limit).
Understanding domain weighting matters because it tells you exactly how to allocate limited study time. A candidate who spends equal hours on all five domains is misallocating effort, since two domains alone - genetic test interpretation and patient counseling - account for the majority of scored content. For a broader look at how difficult the exam is overall, see How Hard Is the CGRA Exam? Complete Difficulty Guide 2026, and for the specific score you need, review CGRA Passing Score 2026: Exactly What You Need to Pass.
Domain 1: Collect and Document Pertinent Patient and Family History (15%)
This domain covers the intake side of cancer genetic risk assessment - the foundational work that happens before any risk model or lab test comes into play. Roughly 15% of scored questions test a candidate's ability to gather accurate, clinically useful family and personal history.
Domain 1 Core Topics
Candidates should be comfortable constructing and interpreting multi-generational pedigrees and recognizing red-flag patterns.
- Constructing a three-generation pedigree with standard symbols and notation
- Identifying missing or unreliable history and how to document uncertainty
- Recognizing hereditary cancer "red flags" - early age of onset, bilateral disease, multiple primary cancers, clustering of related tumor types
- Documenting ethnicity and ancestry factors relevant to founder mutations
Because this domain is comparatively small, it's tempting to skim it. However, weak pedigree skills tend to cause downstream errors in Domain 2 and Domain 3 questions, since risk models and variant interpretation both depend on accurate history. If you need a compact review of terminology and pedigree symbols before test day, the CGRA Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for that kind of quick-reference study.
Domain 2: Perform Personalized Cancer Risk Assessment (18%)
Domain 2 asks candidates to move from raw history to a quantified, individualized risk picture. This is where risk-assessment models, syndrome recognition, and probability-based reasoning converge - accounting for about 18% of scored questions.
Domain 2 Core Topics
Expect scenario-based items that require applying - not just naming - risk assessment concepts.
- Selecting the appropriate risk model or tool for a given clinical scenario
- Differentiating hereditary syndromes based on pattern of cancers and inheritance
- Applying published testing-eligibility criteria to a patient case
- Distinguishing population-level versus personalized risk estimates
This domain frequently appears in the exam as a case vignette followed by a question about "most appropriate next step," which rewards candidates who can reason through a scenario rather than recall an isolated fact. Practicing this reasoning style is one of the most efficient uses of time before the exam - see CGRA Study Guide 2026: How to Pass on Your First Attempt for scenario-based practice strategies specific to this domain.
Domain 3: Interpret Relevant Genetic Test Results (32%)
Domain 3 is the exam's center of gravity. At 32% of scored content, it is nearly a third of the entire test and, combined with Domain 5, accounts for 57% of all scored questions. No candidate should walk into the exam without having deeply mastered this domain.
Domain 3 Core Topics
This domain tests the technical literacy required to translate a lab report into clinical meaning.
- Differentiating pathogenic, likely pathogenic, benign, and variant of uncertain significance (VUS) classifications
- Understanding multigene panel test reports and result formats
- Applying appropriate follow-up when a VUS is reported versus a clearly pathogenic variant
- Recognizing when results conflict with clinical presentation or family history and what that implies
- Understanding penetrance, variable expressivity, and how they affect result interpretation
Key Takeaway
If your study time is limited, prioritize Domain 3 first. Its 32% weight means even modest improvement here moves your overall score more than equivalent effort in any other single domain.
Because interpretation questions often hinge on precise terminology, this domain rewards deliberate repetition of classification language and report-reading practice rather than passive review. Candidates preparing for this domain specifically should also revisit prerequisite clinical experience expectations described in CGRA Requirements 2026: Eligibility, Prerequisites & How to Qualify, since the exam assumes a baseline of hands-on lab-report exposure.
Domain 4: Determine Medical Management Options Based on Genetic Test Results and Risk Factors (10%)
At 10%, Domain 4 is the smallest of the five domains, but it should not be treated as an afterthought. This content bridges interpretation (Domain 3) and counseling (Domain 5) by testing whether a candidate can translate a result into an actionable management plan.
Domain 4 Core Topics
- Matching a confirmed pathogenic result to recommended surveillance intensity or intervals
- Understanding risk-reducing surgical and chemoprevention options at a conceptual level
- Recognizing when management should differ based on family history alone versus a confirmed genetic result
- Identifying situations requiring referral to specialists beyond the risk-assessment provider's scope
Because this domain is smaller, some candidates deprioritize it entirely - a mistake, since every scored question still carries the same per-item value toward the 71% passing threshold. A handful of missed Domain 4 questions can be the difference between passing and needing a retake.
Domain 5: Effectively Communicate With and Counsel Patients (25%)
Domain 5 is the second-largest domain at 25% and pairs directly with Domain 3 to form the exam's dominant content pairing (57% combined). This domain tests the interpersonal and ethical dimension of cancer genetic risk assessment - how results and risk information are actually delivered to patients and families.
Domain 5 Core Topics
- Delivering positive, negative, and uncertain (VUS) results in a way patients can understand
- Addressing informed consent before and after genetic testing
- Managing family communication implications, including at-risk relatives
- Recognizing psychosocial responses to genetic risk information and adjusting counseling approach
- Applying professional and ethical boundaries in genetic counseling scenarios
Communication-domain questions are often written as "best response" scenarios rather than fact-recall items, which means candidates need to practice reading tone and context, not just memorize a script. This domain is frequently underestimated by candidates with strong technical backgrounds but limited counseling exposure - a gap worth closing well before exam day.
| Domain | Weight | Primary Skill Tested |
|---|---|---|
| Domain 1: History Collection | 15% | Pedigree accuracy and red-flag recognition |
| Domain 2: Risk Assessment | 18% | Model selection and syndrome differentiation |
| Domain 3: Genetic Test Interpretation | 32% | Variant classification and lab report literacy |
| Domain 4: Medical Management | 10% | Translating results into surveillance/management plans |
| Domain 5: Patient Communication/Counseling | 25% | Delivering results and supporting patient decisions |
Weighting Strategy: Where to Spend Your Study Hours
With five domains and uneven weighting, a proportional study strategy makes sense: allocate roughly a third of your review time to Domain 3, about a quarter to Domain 5, and split the remaining time across Domains 1, 2, and 4 in rough proportion to their weights. This isn't a rigid formula, but it prevents the common mistake of spending equal time on a 10%-weighted domain and a 32%-weighted domain.
This weighting also has implications for how you interpret your own practice performance. If you're consistently missing Domain 3 questions on practice sets, that's a bigger red flag than the same miss rate on Domain 4, simply because of the scoring math. Our full-length CGRA practice tests break results out by domain so you can see exactly where your weak points sit relative to the 71% passing threshold.
A Domain-Ordered Study Timeline
Generic study techniques like spaced repetition or timed review blocks only help if they're pointed at the right content in the right order. Below is one way to sequence preparation around the CGRA domain weights rather than studying domains in numerical order out of habit.
Domain 3 Foundations
- Review variant classification categories and VUS handling
- Practice reading multigene panel report formats
Domain 5 Communication Scenarios
- Work through result-disclosure vignettes
- Review informed consent and family communication issues
Domain 2 Risk Models
- Practice matching scenarios to appropriate risk tools
- Drill syndrome differentiation questions
Domains 1 and 4
- Tighten pedigree construction and red-flag recall
- Review management options tied to specific result types
Full-Length Practice and Review
- Take timed practice exams under 3-hour conditions
- Re-review any domain scoring below your target

Domain Prep Meets Exam Logistics
Domain mastery only matters if you're actually eligible and registered in time to sit for the exam. Applications must be submitted at least two weeks before your intended testing date, and the official handbook is emailed within seven days of approved registration - so build domain study around that timeline rather than around it. If you're still confirming licensure hours or clinical experience prerequisites, check CGRA Requirements 2026: Eligibility, Prerequisites & How to Qualify before committing to a study schedule. For scheduling specifics, CGRA Exam Dates 2026: Testing Windows, Deadlines & Scheduling covers testing windows in more detail.
It's also worth understanding what a missed pass costs in terms of time and money: retakes require at least six months between attempts, and while the first retake within 12 months carries no additional exam fee, an attempt after a second failure costs $495. Studying domain-by-domain with attention to the 32%/25% weighting is one of the more direct ways to avoid that scenario. Full fee details are broken down in CGRA Certification Cost 2026: Complete Pricing Breakdown.
Frequently Asked Questions
Domain 3, Interpret Relevant Genetic Test Results, carries the largest weight at 32% of scored content, making it the single most important domain to master.
Yes. Genetic test interpretation (32%) and patient communication/counseling (25%) together account for 57% of all scored questions on the CGRA exam.
No. Because domain weights range from 10% to 32%, proportional study time based on each domain's weight is more efficient than an equal split across all five.
No. Every scored question counts equally toward the 71% passing score, so neglecting even a 10%-weighted domain can affect whether you pass.
Domain-tagged practice questions let you target weak areas directly; you can work through full practice exams at the main CGRA practice test platform to see performance broken out by each of the five domains.
