1. A BCBA records that a client emitted 15 responses in a 30-minute session. What is the response rate per minute? → 0.5 responses per minute
2. What is the purpose of supervision in ABA? → To guide and support the practitioner in delivering ethical interventions
3. A 'tact' in Skinner's verbal behavior framework is a verbal operant that: → Is evoked by a nonverbal discriminative stimulus and generalized conditioned reinforcement
4. In the Enhanced Milieu Teaching (EMT) model, a 'time delay' procedure is used to: → Create an expectant pause that prompts the child to initiate communication
5. A child only responds correctly when the therapist leans forward before presenting the SD. This is an example of: → Stimulus overselectivity or inadvertent prompting
6. Which of the following represents an appropriate boundary when collaborating with caregivers? → Maintaining a professional relationship while being warm, respectful, and empathetic
7. A learner is reinforced for the first correct response after a variable period of time (averaging 2 minutes). Which schedule is this? → Variable interval 2-minute
8. A stimulus class is defined as a group of stimuli that: → All produce the same reinforced response or participate in the same derived relations
9. Which term describes a stimulus that precedes behavior and signals that reinforcement is available? → Discriminative stimulus (SD)
10. A BCBA discovers that a colleague is misrepresenting data in progress reports. Under BACB ethics, what is the BCBA's primary obligation? → Report the concern through appropriate channels, such as the BACB or a supervisor
11. A student with autism responds correctly to the teacher's question only when the teacher is wearing a red shirt, not any other shirt. This is an example of: → Overselective stimulus control
12. In a tandem schedule, reinforcement is produced when the requirements of two schedules are met in sequence. What distinguishes tandem from chained schedules? → Tandem has no discriminative stimuli correlated with each component; chain does
13. Self-monitoring is encouraged in ABA supervision primarily because it: → Builds the supervisee's capacity for independent professional reflection and improvement
14. A BCBA changes from CRF to a VR-5 schedule after a skill is acquired. If the learner shows a dramatic drop in responding, the most likely issue is: → The schedule was thinned too rapidly
15. During discrete trial training (DTT), what is the purpose of the inter-trial interval (ITI)? → To provide a brief pause that separates one trial from the next and reduces error
16. What is the primary purpose of training caregivers to collect data on target behaviors? → To extend data collection to natural environments and support decision-making
17. Errorless learning differs from trial-and-error learning primarily because it: → Arranges antecedent conditions to prevent errors during acquisition
18. A ABA professional encounters an unfamiliar situation while performing parent & caregiver collaboration duties. What is the most appropriate first action? → Consult relevant standards, guidelines, or a qualified supervisor before proceeding
19. Which level of measurement produces data that can be ordered and has equal intervals but no true zero point? → Interval
20. Social stories are MOST consistent with which behavioral principle? → Antecedent-based intervention (ABI)
21. A child learns to request 'juice' only when juice is visible and not when other drinks are present. This outcome best demonstrates which behavioral process? → Stimulus discrimination
22. Momentary time sampling is best suited for measuring behaviors that are: → Continuous and occur at very high rates
23. A BCBA wants to measure the duration of a client's tantrum behavior. Which data collection method is most appropriate? → Duration recording
24. A behavior that is reinforced by removing an aversive stimulus is maintained by: → Negative reinforcement
25. Which of the following is a fundamental principle of aba principles & terminology as it applies to Applied Behavior Analyst Certification? → Systematic evaluation and adherence to established industry standards
26. Parent training goals should primarily be driven by: → The family's values, priorities, and the child's individualized needs
27. A behavior analyst is monitoring a decreasing behavior and the data path shows a decelerating trend. How should this be interpreted? → The behavior is decreasing at a consistent rate, suggesting the intervention is working
28. What is the primary ethical obligation of a ABA professional when a conflict of interest arises during clinical supervision models activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
29. When evaluating a completed ABC narrative recording, a BCBA groups similar antecedent-behavior-consequence sequences to identify: → Possible behavioral functions
30. Which of the following represents the highest level of caregiver involvement in ABA services? → Caregiver receives training and implements strategies independently in daily routines
