RAC Devices Exam Domains Explained: All 4 Domains

Starting with the Spring 2026 testing window, RAPS didn't just add questions and time to the RAC (Devices) exam — it reorganized what the exam tests. The old domain structure was retired in favor of four renamed, rebalanced domains that track the medical device regulatory lifecycle from initial strategy through post-market obligations.

If you're preparing for the current exam, understanding what each domain actually covers — not just its name and percentage — is what turns a study plan from "read everything" into "spend the most time where the exam spends the most questions." Here's a breakdown of all four.

Domain I: Strategic Planning (≈27% of the exam)

Strategic Planning is tied for the heaviest-weighted domain, and it sits earliest in the product lifecycle — before a device design is even finalized.

This domain tests your ability to think like the regulatory lead in the room during early product decisions: assessing the regulatory landscape for a product from concept through eventual retirement, building a commercialization strategy that works across multiple markets, and researching competitor and predicate devices to inform positioning. It also covers distinguishing between different product and device designations, evaluating proposed product claims against the testing evidence that will need to support them, and knowing when and how to engage regulatory agencies proactively rather than reactively. A specific sub-theme worth flagging: special patient populations and unusual use environments (pediatric devices, home-use devices, and similar cases) carry their own regulatory considerations that this domain expects you to recognize.

Study focus: global regulatory strategy frameworks, predicate/equivalence research methodology, product classification logic, and pre-submission agency interaction (e.g., FDA Pre-Submission meetings, similar mechanisms in other jurisdictions).

Domain II: Design and Development (≈27% of the exam)

Design and Development is the other heavily-weighted domain, and it's where regulatory strategy meets engineering and quality execution.

This domain covers reviewing and approving design verification and validation activities and their supporting deliverables, confirming that testing results actually support the claims a company intends to make, and evaluating substantial equivalence or state-of-the-art determinations against predicate device performance. It also tests your judgment on the regulatory impact of design or manufacturing changes made mid-development, your ability to participate meaningfully in design and risk review activities, and your understanding of how quality management system elements need to be in place to support design, development, transfer, and marketing. Contract and documentation oversight — including confidentiality and data protection controls — and communicating with regulatory agencies during development both fall here too.

Study focus: design controls and DHF structure, verification vs. validation, substantial equivalence reasoning, risk management integration (ISO 14971) into design review, and QMS touchpoints during development (ISO 13485, 21 CFR 820).

Domain III: Process for Licensing, Registration, and Renewals (≈23% of the exam)

This is the domain most people associate with "actually doing regulatory affairs" — the submission and registration mechanics.

It covers determining what documentation a given licensing, registration, or renewal actually requires, coordinating internal stakeholders to support a submission, and assembling and submitting filing data in an acceptable format to the relevant authority. It also tests how to respond to deficiency or query letters, when and how to update an existing license or registration after a critical change, and how to track the status of licenses and registrations across markets. Communication and negotiation with regulatory authorities during this process, along with customs and import/export documentation requirements, round out the domain.

Study focus: submission types and formats across major markets (510(k), PMA, De Novo, EU MDR technical documentation, and equivalent pathways in other jurisdictions), deficiency-response strategy, and multi-market registration tracking.

Domain IV: Post-Market Activities (≈23% of the exam)

Post-Market Activities is where the exam shifts from "getting a device to market" to "keeping it there responsibly."

This domain tests your ability to assess and document the regulatory impact of product, process, or quality system changes after launch, and to interpret how external changes (new regulations, updated standards, shifting guidance) affect an already-marketed device. It covers supporting health authority and notified body commitments, assessing risk and reportability determinations for post-market events, and evaluating the regulatory impact of labeling or promotional material changes. Maintaining technical files and dossiers on an ongoing basis, negotiating with regulatory authorities post-launch, and participating in internal product review committees are also part of this domain — alongside handling import/export documentation, legal requests, and reimbursement-related submissions that come up after commercialization.

Study focus: post-market surveillance systems, medical device reporting/vigilance obligations, change-impact assessment (what triggers a new submission vs. a notification vs. no action), and technical file/CER maintenance.

How the Domain Weighting Should Shape Your Study Plan

With Strategic Planning and Design and Development together accounting for roughly 54% of the exam, a study plan that treats all four domains equally is already misallocating over half your prep time. That doesn't mean skimming Licensing/Registration or Post-Market Activities — each is still worth roughly a quarter of the exam — but it does mean the depth of your review should track the weighting, not just the domain count.

It's also worth noting that these four domains don't map cleanly onto older RAC (Devices) study material. Content organized around the pre-2026 structure may cover similar topics but group and weight them differently, which can leave gaps exactly where the current exam concentrates its questions.

Study Material Built Around the Current Domain Structure

The AptSkill RAC Devices Master Handbook, Second Edition was restructured specifically around these four domains and their current weighting — Strategic Planning, Design and Development, Process for Licensing/Registration/Renewals, and Post-Market Activities — rather than adapted after the fact from older material. It pairs each domain with 900+ practice questions and case-based mini-mocks, along with global regulatory coverage across FDA, EU MDR, Health Canada, MHRA, PMDA, NMPA, TGA, CDSCO, and ANVISA.

Frequently Asked Questions

How many domains are on the RAC Devices exam? Four: Strategic Planning (~27%), Design and Development (~27%), Process for Licensing, Registration, and Renewals (~23%), and Post-Market Activities (~23%).

Which RAC Devices domain carries the most weight? Strategic Planning and Design and Development are tied for the heaviest weighting, at roughly 27% each — together, more than half the exam.

Is Professional Ethics a separate scored domain? No. Ethics-related knowledge is tested as part of the required knowledge running through all four domains rather than as its own scored section.

Did the RAC Devices domains change for 2026? Yes. Starting with the Spring 2026 testing window, RAPS renamed and rebalanced the domain structure alongside expanding the exam to 120 questions over 2.5 hours.

Where can I find the official domain task list? RAPS publishes an official RAC-Devices Exam Study Checklist and Candidate Guide with the full task statements for each domain — download the current version from raps.org before finalizing your study plan.

Domain names, weightings, and task statements reflect RAPS's official RAC-Devices Exam Study Checklist. RAPS reviews and can revise the exam outline periodically — always confirm the current version at raps.org before your exam.
