ACCA BT Exam 2025 Format, Question Types,
Pass Rate, and Best Study Materials
Question 1: Leonard gives Sheldon a token about every 5th time Sheldon responds correctly.
After Sheldon earns 5 tokens, he can exchange them for 10 minutes of video games time.
Sheldon is earning tokens on what schedule of reinforcement?
A. Variable Ratio
B. Variable Interval
C. Fixed Ratio
D. Fixed Interval
Rationale: The correct answer is A. Variable Ratio. Reinforcement is delivered after an
unpredictable number of responses (<em>about</em> every 5th time). The exchange of 5
tokens for video game time describes a token economy, but the schedule for earning individual
tokens is variable ratio.
Question 2: Food, sex, water, breathable air, and any other stimuli that are necessary for life are
what types of reinforcement?
A. Ontogenic
B. Unconditioned
C. Ethically required
D. Conditioned
Rationale: The correct answer is B. Unconditioned. Unconditioned reinforcers (also known as
primary reinforcers) are stimuli that are inherently reinforcing because they satisfy a biological
need and do not require learning to be effective.
Question 3: How many face-to-face supervision contacts are required every month?
A. 5
B. None
,C. 2
D. 1
Rationale: The correct answer is C. 2. According to the Behavior Analyst Certification Board
(BACB) requirements for RBTs at the time of many common training materials, RBTs must
receive supervision for a minimum of 5% of their behavior-analytic service hours per month,
which must include at least 2 face-to-face (live, synchronous) contacts with their supervisor.
Question 4: Which of the following is an example of a stimulus control transfer procedure?
A. Pairing the instructions, "Make a sandwich" with a video model, then fading the video model
until the patient can make a sandwich when given the instruction only.
B. Offering choices of a sandwich or salad for lunch.
C. Giving praise for making a sandwich within a 5-minute interval
D. Having the patient discriminate between making a sandwich and making popcorn when given
a specific instruction
Rationale: The correct answer is A. Pairing the instructions, "Make a sandwich" with a
video model, then fading the video model until the patient can make a sandwich when given
the instruction only. This describes a process where control over the behavior (making a
sandwich) is transferred from a more intrusive prompt (video model + instruction) to a less
intrusive stimulus (instruction only).
Question 5: Which of the following is likely a conditioned reinforcer?
A. Receiving social praise when you get an answer correct
B. Earning a drink of water for completing a workout
C. Taking a nap when you need a break from working
D. Earning food breaks for the amount of math problems you complete
Rationale: The correct answer is A. Receiving social praise when you get an answer correct.
Social praise is a conditioned reinforcer because its value is learned through association with
other reinforcers (e.g., primary reinforcers or other conditioned reinforcers). Water, rest (nap),
and food are primary or unconditioned reinforcers.
Question 6: April has recently been assigned on Ron's case. She is preparing for her first session
with him by reading through his targets and behavior support plans, and ensuring she is familiar
with them both before she starts. At the beginning of her session, she greets him and brings out a
few toys. After conducting a preference assessment with the toys, she begins running targets.
, Ron engages in maladaptive behaviors and does not comply with demands. What is most likely
the problem?
A. April did not bring enough toys for Ron to play with
B. There is no problem, this is why Ron needs services
C. April might not be running the targets correctly since the consultant is not there to coach her
D. April did not take enough time to build rapport with Ron before placing demands
Rationale: The correct answer is D. April did not take enough time to build rapport with
Ron before placing demands. Building rapport (pairing) is crucial, especially during initial
sessions. Introducing demands too quickly, before a positive relationship is established and the
therapist is associated with reinforcement, can lead to an increase in maladaptive behaviors and
non-compliance.
Question 7: When teaching a patient to brush their teeth, you demonstrate with your own
toothbrush and teeth. What type of prompt is used?
A. Verbal prompt
B. Stimulus Prompt
C. Modeling
D. Physical prompt
Rationale: The correct answer is C. Modeling. Modeling involves demonstrating the desired
behavior for the learner. In this scenario, the therapist is showing the patient how to brush their
teeth by doing it themselves.
Question 8: A therapist provides a 'star' token every 3 times the learner responds correctly. After
5 tokens, the learner can exchange the tokens for a reinforcer from the reinforcer menu. What
type of schedule of reinforcement is this?
A. Fixed ratio
B. Variable ratio
C. Fixed interval
D. Variable interval
Rationale: The correct answer is A. Fixed ratio. Reinforcement (a star token) is delivered after
a specific, unchanging number of correct responses (every 3 times).
