Domain: Assessment & Referral
Q1. The Human Activity Assistive Technology (HAAT) model provides a framework for AT assessment by
examining the interaction among four components. Which of the following correctly identifies these four
components and their relationship?
A. Human, Activity, Assistive Technology, and Context — where the human uses assistive technology to perform
activities within a contextual environment
B. Human, Activity, Assistive Technology, and Outcome — where outcomes are measured by the degree of
functional independence achieved
C. Human, Disability, Assistive Technology, and Environment — where disability is the central construct that
determines technology needs
D. Client, Therapist, Technology, and Funding — where the therapist mediates between client needs and
available technology resources
Correct Answer: A. Human, Activity, Assistive Technology, and Context — where the human uses assistive
technology to perform activities within a contextual environment
Rationale: The HAAT model, developed by Cook and Polgar, identifies four core components: the Human (the person
with a disability), the Activity (the functional task to be performed), the Assistive Technology (the tool or device), and
the Context (the physical, social, cultural, and institutional environment). The model emphasizes that AT assessment
must consider the dynamic interaction among all four components rather than focusing on any single element in
isolation.
Why Wrong: A: This is correct. B: Wrong because Outcome is not one of the four HAAT components; the fourth
component is Context. C: Wrong because Disability is not a component; the HAAT model uses Activity instead of
framing the person through a disability lens. D: Wrong because Therapist and Funding are not components of the
HAAT model; the framework focuses on the human-activity-technology-context interaction.

5th ed., Ch. 1; RESNA Position Paper on Assessment (2026).
Q2. A client-centered assessment approach in assistive technology prioritizes the perspectives and preferences of
the individual with a disability. Which of the following best exemplifies a truly client-centered approach during an
AT assessment?
A. The ATP collaborates with the client to identify meaningful goals, explores the client's values and lifestyle,
and involves the client in all decision-making about technology options
B. The ATP selects the most technologically advanced device available and trains the client on its use, ensuring
optimal functional performance
C. The ATP conducts a standardized evaluation, selects the device with the highest evidence-based rating, and
presents it as the recommended solution
D. The ATP defers entirely to the client's initial request for a specific device and completes the documentation to
support that choice
Correct Answer: A. The ATP collaborates with the client to identify meaningful goals, explores the client's
values and lifestyle, and involves the client in all decision-making about technology options
Rationale: A client-centered approach requires the ATP to actively engage the client in identifying personally
meaningful goals, understanding their values, preferences, and lifestyle, and involving them as a full partner in all
decisions about technology options. This goes beyond simply selecting the most advanced device, relying solely on
standardized scores, or uncritically accepting a client's initial request without professional assessment and
collaborative exploration.
, Why Wrong: A: This is correct. B: Wrong because selecting the most advanced device without client input is a
technology-driven, not client-centered, approach. C: Wrong because while evidence-based ratings are important,
making the decision without client involvement contradicts client-centered principles. D: Wrong because
deferring entirely without professional assessment is abdication of clinical responsibility, not client-centered care;
the ATP must balance client preference with clinical expertise.
Reference: ATP Certification Reference Material, Ch. 2: Assessment Process; Cook & Polgar, Assistive Technologies,
5th ed., Ch. 4; RESNA Position Paper on Client-Centered Assessment (2026).
Q3. During a functional capacity evaluation (FCE) for assistive technology selection, an ATP assesses a client's
ability to perform work-related tasks after a cervical spinal cord injury at C6. Which functional capability is most
critical to evaluate when considering a powered wheelchair with chin-controlled input?
A. Lower extremity strength and ambulation distance on varied surfaces
B. Mouth movement range, head control, and the ability to produce consistent voluntary chin movements for
directional control
C. Grip strength and fine motor dexterity of the dominant hand for joystick manipulation
D. Trunk balance and sitting tolerance duration without posterior support
Correct Answer: B. Mouth movement range, head control, and the ability to produce consistent voluntary
chin movements for directional control
Rationale: For a client with a C6 cervical spinal cord injury considering a chin-controlled powered wheelchair, the
most critical functional capabilities to evaluate are mouth movement range, head control, and the ability to produce
consistent voluntary chin movements. These directly determine whether the client can effectively and reliably operate
the chin control interface. Without adequate head control and purposeful chin movement, alternative control
methods would need to be explored.
Why Wrong: A: Wrong because lower extremity strength and ambulation are not relevant for a client with C6
tetraplegia considering a powered wheelchair. B: This is correct. C: Wrong because clients with C6 SCI typically
lack the hand function required for joystick manipulation; this is why a chin control is being considered. D: Wrong
because while trunk balance is relevant for seating, it is not the most critical factor for operating a chin-controlled
input device.
Reference: ATP Certification Reference Material, Ch. 3: Functional Evaluation; Cook & Polgar, Assistive Technologies,
5th ed., Ch. 10; RESNA Position Paper on Wheeled Mobility Assessment (2026).
Q4. Activity limitation analysis within the ICF framework helps ATPs identify the gap between a client's current
abilities and the demands of desired activities. Which ICF construct specifically describes the gap between capacity
(what a person can do in a standard environment) and performance (what a person actually does in their current
environment)?
A. Body function impairment
B. Activity limitation
C. Participation restriction
D. Environmental barrier
Correct Answer: D. Environmental barrier
Rationale: In the ICF framework, the difference between capacity (the highest probable level of functioning a person
may achieve in a standard or optimal environment) and performance (what a person actually does in their current
environment) reflects the impact of environmental factors. When performance is lower than capacity, environmental
barriers are present. This gap analysis is critical in AT assessment because it identifies where assistive technology or
environmental modifications can close the performance-capacity gap.
Why Wrong: A: Wrong because body function impairment refers to problems in body functions or structures, not
the gap between capacity and performance. B: Wrong because activity limitation refers to difficulties in executing
activities, which may result from the capacity-performance gap but is not the construct that describes the gap
itself. C: Wrong because participation restriction refers to problems in involvement in life situations, which is a
