NBCOT OTR Domain 2, Analysis, Interpretation, and Planning: Standard Scores, Plans and Precautions

Domain 1 gathers the information; Domain 2 decides what it means and what happens next. Expect items that hand you test scores, interview findings, a team meeting or a change in the client's condition, and ask what to conclude, what to plan or what to change.

Domain 2 on the 2022 OTR outline: three tasks, 12 knowledge statements

The 2022 OTR Examination Content Outline, checked on October 27, 2026, describes Domain 2 as: "Formulate conclusions regarding client needs and priorities to develop and monitor an intervention plan throughout the occupational therapy process." It carries 23% of the exam, about 41 of 180 items by Passy's estimate (each form also includes unscored field-test items in a number NBCOT doesn't publish).

Reading standard scores on the NBCOT OTR exam

"Statistical terminology" and "scoring" are named in Task 1, and score interpretation is where a few minutes of arithmetic practice pays off. One formula does most of the work. NIST's statistics handbook puts it this way: to use the standard normal table, "standardize your value by subtracting the mean and dividing the result by the standard deviation."

z = (score − mean) ÷ standard deviation

The test manual tells you the mean and standard deviation of its scale. Some scales use a mean of 100 and a standard deviation of 15: a 2026 study using the Bayley Scales of Infant and Toddler Development, Third Edition, notes that its composite scores are "normalized to a mean of 100 and standard deviation of 15" (Developmental Medicine and Child Neurology). Others use T-scores; the PROMIS measures, developed through an NIH initiative, "use T-scores with a mean (average) of 50 and standard deviation of 10 in the general population" (HealthMeasures). Once you have z, NIST's standard normal table gives the share of a normal distribution that falls at or below it:

That share is what a percentile rank describes: a score with about 16% of the distribution at or below it sits near the 16th percentile. Two cautions keep you out of common traps:

• Check what the scale measures. HealthMeasures explains that a higher PROMIS T-score means more of the concept being measured, so a high score can reflect better or worse health: more physical function, or more fatigue (Interpret Scores). Read what the stem says the test measures before you interpret the number
• Scores have limits. The outline lists "limitations of scores" and "client reactions to testing" as knowledge in their own right. A result from one session with an anxious or tired client is one data point, not the whole picture

Eligibility cutoffs are set locally, not by the exam

Early intervention is a clear example. Under IDEA Part C, each state's system must include its own "rigorous definition of developmental delay" that specifies "the level of developmental delay in functioning or other comparable criteria" (34 CFR 303.111). So a number of standard deviations that qualifies a child in one state may not in another. When an item asks about eligibility, the stem has to give you the criterion. Don't bring one from memory.

Qualitative findings and the client's priorities

Task 1 pairs scores with qualitative findings: the occupational profile, needs assessments, interviews and observation. Its third knowledge statement asks you to integrate both "to guide critical decision-making and prioritize needs." A plan built only on the lowest score misses half of that statement. When the numbers and the client's stated priorities point in different directions, look for the option that uses both, for example a goal that targets the deficit through the activity the client cares about.

IEPs, IFSPs and other plans in Domain 2

The outline names IEP, discharge, transition, and palliative and hospice plans. The two school and early-childhood plans have rules set in federal regulation:

• IFSP, under IDEA Part C. For infants and toddlers under 3 who need early intervention (303.21). The IFSP must state the child's present levels of development and, with the family's agreement, "the family's resources, priorities, and concerns." Services are provided in the natural environment "to the maximum extent appropriate," or the plan must justify why not (303.344)
• IEP, under IDEA Part B. A written statement for each child with a disability, developed, reviewed and revised in a meeting. Beginning no later than the first IEP in effect when the child turns 16, or younger if the IEP team decides, it must include measurable postsecondary goals for training, education, employment and, where appropriate, independent living, plus the transition services to reach them (300.320)

The CDC adds that for children age 3 and older, "local public school systems typically provide developmental services and support." So when an item asks which plan must contain an element, the family's resources, priorities and concerns are a required part of an IFSP, and measurable postsecondary goals by the first IEP in effect at 16 are a required part of an IEP.

Teach-back and show-me for caregiver training

Task 2's fifth knowledge statement covers health literacy, with caregiver training and "methods for making health information accessible" as examples. AHRQ's Teach-Back Method tool gives a precise rule: teach-back means "asking patients to state in their own words what they need to know or do," and the related show-me method confirms that someone can follow specific instructions. AHRQ is explicit that "Do you understand?" and "Does that make sense?" are not teach-back questions, because people tend to answer yes either way. If the teach-back shows a misunderstanding, explain it differently and ask again.

For an item that asks how to confirm a caregiver can carry out a home program, the strongest option has the caregiver explain it in their own words or demonstrate it, not the therapist asking whether they have questions.

Monitoring the plan: precautions the outline names

Task 3's fourth knowledge statement is "Precautions or contraindications associated with a client's condition or stage of recovery," with postsurgical precautions, vital signs, laboratory values and suicidal ideation as examples. Its third statement adds physiological changes, behavioral reactions, emotion regulation and developmental needs as reasons to adapt the plan. In practice, these are the details in a stem that should change what happens in the session.

Two notes on specific examples:

• Postsurgical precautions are specific to the client's surgery and orders. NBCOT says scenario sets contain all the information you need, so look for the precautions in the scene rather than assuming them. The scenario-set guide works through a hip replacement example option by option
• Suicidal ideation sits in the same list as the physical precautions. NIMH directs anyone who is struggling or having thoughts of suicide to the 988 Suicide & Crisis Lifeline (call or text 988), and to 911 in life-threatening situations (NIMH)

Emergencies during a session, such as seizures and low blood sugar, belong to Domain 4. The Domain 4 guide covers the CDC rules for both.

A Passy practice item for Domain 2

Written by Passy to show the reasoning; it is not an NBCOT item.

A 6-year-old earns a standard score of 70 on a norm-referenced motor test whose manual reports a mean of 100 and a standard deviation of 15. How should the occupational therapist describe this result to the team?

• A. Two standard deviations below the mean, near the 2nd percentile
• B. One standard deviation below the mean, near the 16th percentile
• C. Thirty points below the mean, near the 30th percentile
• D. Within one standard deviation of the mean, near the 50th percentile

Keyed answer: A. (70 − 100) ÷ 15 = −2.00, and NIST's table puts about 2% of a normal distribution at or below z = −2. B is the result for a score of 85. C confuses raw points with percentiles. D would need a score between 85 and 115.

Score items are fast once the formula is automatic, so it's worth drilling them until they take under a minute. You can work standard-score conversions step by step in the planned OTR question bank.

How to study Domain 2 for the OTR

1. Give it about a quarter of your hours: roughly 21 of a 90-hour plan at 23%. The OTR study plan guide places it in the schedule.
2. Drill the formula with made-up scores on both scales until you can convert without writing.
3. Make an IEP and IFSP table from the regulations above and add discharge, transition and hospice plans from your coursework.
4. Practice teach-back wording. Write the exact question you'd ask a caregiver, and check it isn't a yes-or-no question.
5. List the outline's precautions next to the conditions where you met them in fieldwork, then study the ones you never saw.
6. Study it with Domain 1. The Domain 1 guide covers the assessment choices whose results you interpret here.

Interpretation terms such as norm group, percentile rank and standard deviation are worth reviewing in short daily bursts. You can drill Domain 2 terms with the 108 flashcards planned for it once full prep launches.

Today, the 20 free OTR practice questions give a mixed first sample across the four domains. Note which Domain 2 items slowed you down: score conversions, plan types or precautions.

When full prep opens, you can see the 299 Analysis, Interpretation, and Planning questions planned at launch.
