CAQ Exam Domains 2026: Complete Guide to All 15 Content Areas

Understanding the CAQ Exam Blueprint

The Certificate of Added Qualification in Adolescent Medicine (CAQ) is administered under the American Board of Family Medicine, with the examination itself developed jointly by ABFM, the American Board of Pediatrics, and the American Board of Internal Medicine. ABP handles administration, and the test is delivered at Prometric testing centers as a proctored, computer-based exam. For family physicians pursuing initial certification, this shared-content structure means the exam pulls from adolescent-specific clinical knowledge that spans multiple organ systems and psychosocial domains rather than a single narrow specialty focus.

ABFM's 2026 Examination Information Booklet lists 15 named content topics that make up the subject matter of the exam. These are presented as a topic list rather than a fully weighted blueprint, meaning the booklet does not publish exact percentage weights for each area. That distinction matters for how you plan your preparation: instead of memorizing a percentage breakdown, you should treat every domain as fair game and calibrate study time based on clinical complexity and how frequently each topic appears in adolescent primary care.

All 15 CAQ Content Domains Explained

Below is the full list of content areas identified in ABFM's 2026 booklet for the Adolescent Medicine CAQ. Each domain reflects a cluster of clinical knowledge a fellowship-trained family physician is expected to apply to adolescent patients specifically - not general internal medicine or general pediatrics.

If you want a deeper dive into how these topics translate into question stems and scenario-based items, our companion piece on how to pass the CAQ on your first attempt walks through practical prep strategies aligned to this exact list.

How the Domains Are Actually Tested

Every domain above is assessed within a single, unified four-hour proctored session - there is no separate module or section per domain. Questions are delivered in a closed-book, computer-based format at Prometric centers, and candidates cannot bring personal calculators or outside study materials into the testing room. Because ABP sets the passing standard before the administration and that standard is shared across the participating boards, there is no incentive to leave questions blank: guessing is not penalized.

This matters for how you approach domain review. Rather than mentally partitioning your prep into 15 discrete silos, expect the exam to interweave domains within case vignettes - a single stem about an athlete with amenorrhea, for example, could touch Endocrine and Metabolism, Nutrition and Eating Disorders, and Musculoskeletal Diseases simultaneously. For a full breakdown of what the scoring threshold looks like in practice, see CAQ Passing Score 2026: Exactly What You Need to Pass.

Which Domains Deserve the Most Study Time

Since ABFM's published list does not assign percentage weights, prioritization should be driven by clinical frequency and complexity rather than a guessed scoring formula. A few domains consistently demand deeper review because they combine broad differential diagnoses with adolescent-specific nuance that differs meaningfully from adult or younger-pediatric practice.

The remaining domains - Musculoskeletal Diseases, Endocrine and Metabolism, Collagen Vascular Diseases, Hematology/Oncology, Cognition, Renal Disease, Infectious Diseases, Gastrointestinal Diseases, Dermatology, Social/Emotional Development and Family/Chronic Illness, and Disease Prevention - still require solid command, since the exam draws case material broadly across all 15 areas. For a candid assessment of how challenging this breadth makes the exam overall, read How Hard Is the CAQ Exam? Complete Difficulty Guide 2026.

Building a Domain-by-Domain Study Timeline

A structured review calendar helps you cycle through all 15 domains without over-indexing on a few favorites. The template below groups domains by clinical theme so related concepts reinforce each other, then reserves dedicated time for mixed-domain practice questions that mimic the exam's blended vignette style.

This is one reasonable sequencing, not a mandated order - spacing repeated exposure to each domain across several weeks (rather than cramming one domain at a time) tends to improve retention for exams built on integrated case vignettes.

Registration, Fees, and Eligibility Basics

Domain preparation only matters if you're actually eligible to sit for the exam. Initial CAQ eligibility requires ABFM certification in good standing, compliant medical licensure and professionalism history, and at least 24 months of ACGME-accredited Adolescent Medicine fellowship training completed after family medicine residency, verified by the program director. A full walkthrough of these prerequisites is available in CAQ Requirements 2026: Eligibility, Prerequisites & How to Qualify.

On the financial side, ABFM's 2026 booklet identifies a full examination fee of USD 1,300, which includes a non-refundable USD 200 application-processing component. After certification, maintaining the CAQ involves an annual continuing-certification process fee of USD 100. For a complete cost breakdown across the certification lifecycle, see CAQ Certification Cost 2026: Complete Pricing Breakdown.

Once certified, physicians maintain their credential through continuous certification with no printed expiration date, contingent on keeping family medicine certification current, paying annual CAQ fees, and completing required longitudinal assessment. Newly certified physicians begin MOCA-Peds in their sixth year of certification, working through five-year maintenance cycles.

How Domain Mastery Translates Into Practice

The 15 domains aren't just exam content - they map directly onto the daily scope of adolescent medicine practice. Physicians who hold this CAQ are typically sought by academic adolescent medicine clinics, school-based health centers, college health services, and pediatric or family medicine practices building out dedicated teen health programs. Strength across domains like Mental Health, Reproduction including Sexuality and STDs, and Substance Abuse is often what distinguishes CAQ-holders in hiring conversations, since these areas require confidence handling sensitive, high-stakes conversations independently.

If you're weighing whether the credential is worth the fellowship time and exam investment, our analysis in Is the CAQ Certification Worth It? Complete ROI Analysis 2026 looks at this question in depth, and CAQ Salary Guide 2026: Complete Earnings Analysis covers how the credential factors into compensation conversations. For candidates actively job-hunting post-certification, CAQ Jobs outlines where employers are actually looking for this specific credential.

Before your test date, running through realistic, domain-mapped practice questions is one of the most reliable ways to confirm you can apply - not just recall - each of the 15 areas. You can start building that familiarity with timed practice sets on the main CAQ practice test platform, which mirrors the blended-vignette style described throughout this guide.
