Overview of the 2022 OTR Examination Content Outline
Every question on the OTR certification exam is written to a specific line item inside the 2022 OTR Examination Content Outline, revised in January 2025 by the National Board for Certification in Occupational Therapy (NBCOT). If you're building a study plan without opening that outline first, you're studying blind. The outline organizes the entire scope of entry-level occupational therapy practice into four domains, each weighted differently on the exam, and each domain maps to a distinct phase of the occupational therapy process - from gathering data to closing out a case.
Understanding domain weighting matters because it tells you where your study hours produce the biggest score gains. A domain worth 38% of the exam deserves proportionally more of your review calendar than one worth 16%. This guide breaks down all four domains in the detail you need to plan a realistic prep schedule, and pairs well with our OTR Study Guide 2026 if you're ready to build a full first-attempt strategy.
Domain 1: Evaluation and Assessment (23%)
Domain 1 covers everything that happens before a plan of care exists. This is the referral, screening, chart review, occupational profile, and formal assessment stage. Items in this domain test whether you know how to select an appropriate assessment tool, gather occupational history, and identify a client's performance patterns, contexts, and environments.
Evaluation and Assessment
Candidates must demonstrate the ability to collect and interpret data that establishes a baseline for intervention planning.
- Selecting standardized and non-standardized assessment tools appropriate to setting, diagnosis, and age
- Conducting occupational profiles and synthesizing client-reported priorities
- Screening for safety risks, precautions, and contraindications before hands-on evaluation
- Interpreting evaluation data within the context of performance skills, patterns, and client factors
Because this is the first domain in the process, it's tempting to treat it as "easy foundational content" and rush past it. Don't. Many candidates lose points here not because they don't know an assessment exists, but because they misjudge which tool fits a specific scenario's constraints - time available, setting, payer requirements, or client cognitive status.
Domain 2: Analysis, Interpretation, and Planning (23%)
Domain 2 picks up immediately after evaluation ends. Once data is collected, you must analyze it, identify occupational performance problems, and translate findings into a coherent plan of care with goals, frames of reference, and a proposed intervention approach.
Analysis, Interpretation, and Planning
This domain tests clinical reasoning - the bridge between raw data and action.
- Synthesizing evaluation results into a prioritized problem list
- Writing measurable, occupation-based goals tied to client priorities
- Selecting theoretical frames of reference and practice models appropriate to the case
- Determining discharge criteria and anticipated outcomes early in the planning process
Domains 1 and 2 together make up 46% of the exam, meaning nearly half your scored items live in the "before intervention begins" phase of practice. If you understand how these two domains connect - evaluation feeds directly into planning - you'll answer scenario questions faster because you'll recognize which stage of the process the item is actually testing.
Key Takeaway
Read scenario stems carefully to identify whether the question is asking about Domain 1 (what data to gather) or Domain 2 (what to do with data already given). Confusing the two is a common source of missed points.
Domain 3: Select and Manage Interventions (38%)
This is the domain that decides whether you pass or retake. At 38%, Select and Manage Interventions is larger than Domains 1 and 2 combined would need to be to catch up, and it is the single most heavily tested content area on the OTR exam.
Select and Manage Interventions
Candidates must show they can implement, grade, and adjust interventions across the full range of practice settings and populations.
- Selecting intervention approaches (remediation, compensation, education, prevention) matched to client goals
- Grading activity demand up or down based on client response and progress
- Managing therapeutic use of self, group dynamics, and caregiver/family training
- Monitoring intervention effectiveness and modifying the plan when outcomes stall
- Applying safety precautions, universal precautions, and infection control during intervention
- Recommending assistive technology, adaptive equipment, and environmental modifications
Because this domain spans so much ground - physical rehab, mental health, pediatrics, geriatrics, community-based practice - it's also where generic review falls apart fastest. A candidate who studied intervention selection for orthopedic hand therapy but skipped psychosocial group intervention strategies will feel confident until the exam pulls a scenario from an unfamiliar setting.

Domain 4: Competency and Practice Management (16%)
Domain 4 is the smallest domain, but it's not optional review. This domain covers the professional, ethical, and administrative responsibilities that surround direct client care - documentation, supervision, reimbursement, and professional development.
Competency and Practice Management
This domain evaluates whether a candidate understands the professional infrastructure that supports safe, compliant practice.
- Documentation standards, timeliness, and reimbursement-driven requirements
- Supervision of OT assistants, aides, and students within scope-of-practice rules
- Adherence to the NBCOT Code of Conduct and applicable regulatory/legal standards
- Interprofessional collaboration and continuing competency responsibilities
Candidates sometimes deprioritize this domain because it feels less "clinical," but 16% of a 180-item exam is still a meaningful chunk of scored questions. Weak performance here is an avoidable, easily fixable gap since much of this content is procedural and rule-based rather than requiring complex clinical judgment.
How Domains Map to Question Format
The OTR exam isn't a flat list of 180 identical questions - it mixes formats, and understanding which format tends to appear where helps you practice more efficiently. The computer-based exam uses three- and four-option single-response multiple-choice items alongside six-option multi-select scenario sets, all administered through Pearson as NBCOT's exclusive test administration partner. You have four hours to complete all 180 items, some of which are unscored field-test questions you won't be able to distinguish from scored ones.
| Domain | Weight | Process Stage |
|---|---|---|
| Evaluation and Assessment | 23% | Before intervention |
| Analysis, Interpretation, and Planning | 23% | Before intervention |
| Select and Manage Interventions | 38% | During intervention |
| Competency and Practice Management | 16% | Surrounding practice |
Multi-select scenario sets tend to cluster around complex, multi-step cases - which frequently touch Domain 3 because intervention scenarios naturally involve several correct actions (grading an activity, addressing safety, and involving a caregiver, for instance, might all be correct within one scenario). Single-response items are more evenly distributed across all four domains. Practicing with realistic question formats matters as much as knowing content - you can start building that familiarity with timed practice sets on our OTR practice test platform.
Allocating Study Time by Domain Weight
A common and avoidable mistake is splitting study time evenly across four domains - 25% each - when the actual exam blueprint is nowhere near that even. If your study calendar doesn't reflect the 23/23/38/16 split, you're misallocating hours relative to how the exam is actually built.
Domain 1 & Domain 2 Foundations
- Review evaluation tools and occupational profile frameworks
- Practice writing goals and selecting frames of reference from case data
Domain 3 Deep Dive
- Work through intervention scenarios across physical, mental health, and pediatric settings
- Drill activity grading, safety precautions, and equipment recommendations
Domain 4 & Integration
- Review documentation, supervision, and Code of Conduct expectations
- Take full-length timed practice sets mixing all four domains
Notice that Domain 3 gets roughly double the calendar time of Domains 1 or 2 individually, reflecting its 38% weight. This isn't generic scheduling advice applied arbitrarily - it's a direct response to how NBCOT weights the outline. For a more detailed week-by-week breakdown tailored to your test date, see the OTR Study Guide 2026.
Common Domain-Level Mistakes
- Treating Domain 1 as trivial: Assessment selection errors are a frequent, preventable point loss.
- Under-preparing Domain 3's breadth: Candidates often master one practice setting's interventions and neglect others within the same 38% domain.
- Skipping Domain 4 entirely: At 16%, this domain is small but still scored - ignoring it leaves points on the table for content that's largely memorization-based.
- Studying without the current outline: The 2022 outline was revised in January 2025; studying an outdated version risks misaligned content weighting.
If you're still deciding whether your prep timeline and difficulty expectations are realistic, our How Hard Is the OTR Exam? guide and OTR Pass Rate data put domain difficulty in context alongside NBCOT's published first-attempt outcomes. And once you're confident in your domain knowledge, timed practice sets on our practice exam platform are the best way to confirm readiness before scheduling with Pearson.
Frequently Asked Questions
Start with Evaluation and Assessment (Domain 1) since it establishes the data-gathering foundation that Domain 2's analysis and planning content builds on, then move into the larger Select and Manage Interventions domain.
At 38%, it's larger than any single other domain, though Domains 1 and 2 together (46%) still represent more combined weight. Balance your schedule so Domain 3 gets the most individual attention while Domains 1 and 2 aren't neglected.
Items are drawn according to the outline's weighting, so across the 180-item exam you should expect proportionally more Select and Manage Interventions questions than Competency and Practice Management questions.
NBCOT publishes the 2022 OTR Examination Content Outline, revised January 2025, which lists every task and knowledge statement within each of the four domains.
Yes - the content outline and its domain weighting apply to every administration of the exam, whether it's your first attempt or a retake after the required waiting period.
