AAC Outcome Measurement & Progress Tracking 3 — Questions and Answers
Question 1: The Communication Matrix is most appropriate for measuring outcomes in AAC users who:
- Have advanced literacy and use text-based AAC
- Communicate at pre-intentional to early symbolic levels (Correct answer)
- Primarily use low-tech communication boards
- Are adolescents with acquired neurological conditions
Correct answer: Communicate at pre-intentional to early symbolic levels
The Communication Matrix assesses early communicative behaviors from pre-intentional signals through early symbol use, making it ideal for individuals with complex needs at early communication stages.
Question 2: Which outcome framework emphasizes measuring AAC effectiveness across Body Function, Activity, and Participation domains?
- DSM-5 Classification
- International Classification of Functioning, Disability and Health (ICF) (Correct answer)
- Bloom's Taxonomy
- IDEA Eligibility Criteria
Correct answer: International Classification of Functioning, Disability and Health (ICF)
The ICF framework guides holistic AAC outcome measurement by addressing impairment, functional activity, and participation in real-life contexts.
Question 3: A clinician calculates that a student's aided language output has increased from 20 to 35 multi-symbol messages per session. Which outcome dimension does this best reflect?
- Communication competence — social
- Communication rate and complexity (Correct answer)
- Receptive vocabulary breadth
- Device feature matching accuracy
Correct answer: Communication rate and complexity
An increase in multi-symbol messages reflects growth in communication rate and linguistic complexity, both key dimensions of AAC outcome.
Question 4: When establishing a baseline for AAC progress monitoring, data should be collected across a minimum of how many data points before beginning intervention?
- 1
- 2
- 3 (Correct answer)
- 5
Correct answer: 3
A minimum of 3 stable baseline data points is generally required to establish a reliable trend before implementing an AAC intervention.
Question 5: The Participation Model for AAC intervention uses assessment of 'opportunity barriers' to guide outcome targets. An opportunity barrier is best defined as:
- A physical limitation that prevents device use
- An external policy, attitude, or practice that restricts participation (Correct answer)
- Insufficient vocabulary on the AAC device
- Low motivation to communicate with peers
Correct answer: An external policy, attitude, or practice that restricts participation
Opportunity barriers are external factors—such as restrictive policies or attitudes of communication partners—that limit the AAC user's chances to communicate, regardless of their skills.
Question 6: Which of the following is a criterion-referenced approach to AAC outcome measurement?
- Comparing performance to age-matched peer norms
- Measuring skill against a predetermined mastery criterion (Correct answer)
- Ranking the student within the classroom
- Using standard scores from a published test
Correct answer: Measuring skill against a predetermined mastery criterion
Criterion-referenced measurement evaluates performance against a specific mastery standard rather than a norm group, common in AAC goal tracking.
Question 7: A team wants to determine if gains made with AAC in the therapy room transfer to the lunchroom and playground. They are measuring:
- Internal validity
- Generalization of communication skills (Correct answer)
- Social validity of the AAC system
- Maintenance of device programming
Correct answer: Generalization of communication skills
Generalization refers to the transfer of learned AAC skills to untrained settings, partners, or materials—a critical outcome dimension for real-world communication.
