Domain 01: Evaluation and Assessment

23% of the NBCOT exam · blueprint OTR examination content outline, January 2024

Short answer

Domain 01 is 23% of the OTR exam. It covers acquiring information about the factors that influence occupational performance throughout the OT process: building an occupational profile, screening, selecting and administering standardised and non-standardised assessments, analysing performance skills and patterns, identifying client factors, and evaluating the contexts and environments in which occupations happen.

Why it matters on this exam

Nearly a quarter of the OTR exam, and it sets up Domain 02: an item often gives you assessment data and asks what you would gather next or which tool answers the referral question.

Key concepts

Occupational profile: the client's history, patterns of daily living, interests, values and needs — collected before, not after, standardised testing.
Choosing a tool: match the construct, the age range and the setting. A norm-referenced test answers "how does this client compare"; a criterion-referenced test answers "can this client do this".
Standardisation matters: changing instructions, materials or positioning invalidates norms. If you must modify, report the result as descriptive rather than standardised.
Performance analysis: observe the occupation itself, not only component skills — an activity analysis identifies where performance breaks down.
Contexts and environments: physical, social, cultural, personal, temporal and virtual; a home evaluation answers questions a clinic cannot.
Precautions during evaluation: weight bearing, sternal, cardiac, seizure and cognitive precautions shape what you can safely assess.

Common mistakes

Administering a battery before establishing the occupational profile, then having no context for the scores.
Reporting modified administration as a standardised score.

Worked example

A client after right CVA is referred for "self-care difficulty". Before the ADL assessment, the occupational profile establishes which self-care tasks they actually performed before the stroke and which matter to them now — that decides which tasks the assessment should sample.

Original practice questions

Domain 01: Evaluation and AssessmentDifficulty 2/5

Which information should the OTR gather first when beginning an evaluation?

AThe occupational profile describing the client's history, roles and priorities
BA full cognitive screening battery to establish the baseline for planning
CThe physician's orders and the expected length of stay for the admission
DStandardised strength and range-of-motion measurements for the affected limb

Show answer and rationale

Correct: A. The occupational profile establishes what the client did, values and needs, which determines the assessments worth administering and the occupations worth targeting. Component measures without that context cannot be interpreted meaningfully.

D — Component measures come after the profile has identified what matters.
B — A full cognitive battery may not be indicated at all until the profile shows a need.
C — Orders and length of stay are administrative context rather than evaluation data.

Domain 01: Evaluation and AssessmentDifficulty 3/5

An OTR modifies the instructions of a standardised assessment so a client with aphasia can participate. How should the results be reported?

AAs standardised scores, because the client completed every required item
BAs descriptive observations, because modification invalidates the norms
CAs standardised scores with the modification noted in the discharge summary
DAs an incomplete assessment that provides no usable clinical information

Show answer and rationale

Correct: B. Altering instructions, materials or positioning removes the conditions under which the norms were established, so normative comparison is no longer valid. The observations remain clinically useful and should be reported descriptively.

A — Completing the items under altered conditions does not restore the norms.
C — Noting the modification later does not make the standardised score valid.
D — The information is still useful; it is simply not normative.

Domain 01: Evaluation and AssessmentDifficulty 2/5

Which assessment setting best answers whether a client can manage bathing safely at home?

AA standardised ADL scale administered on the inpatient unit
BA clinic simulation using a standard therapy tub and grab bars
CA home evaluation in the client's own bathroom with their equipment
DA self-report questionnaire about bathing independence before discharge

Show answer and rationale

Correct: C. Performance depends on the actual environment: fixture height, tub wall, lighting, space and available equipment differ from any simulation. A home evaluation is the only setting that answers the question directly.

B — Clinic fixtures rarely match the client's own bathroom.
D — Self-report is affected by insight and recall rather than observed performance.
A — A unit-based scale measures capacity, not performance in context.
