Behavior Acquisition (Skill Acquisition): RBT Area C Study Guide

Free RBT Practice Test Editorial Team | Updated September 2026

Area C, Behavior Acquisition, accounts for 19 of the 75 scored questions on the RBT exam, or 25% of your score, making it the largest single area. Since January 1, 2026 the exam has followed the RBT Test Content Outline (3rd Edition), which renamed the old Skill Acquisition domain and reorganized it into eleven tasks, C.1 through C.11. This guide explains each task in plain English, gives a session example, and includes two scenario questions per task so you can check yourself before the full practice test.

Teaching new behavior is the heart of what an RBT does every day, whether that is helping a child request items with picture cards or supporting a teen learning vocational skills. Every program you run starts with a written plan from the supervising behavior analyst that spells out the target, the teaching procedure, the reinforcers, the data to collect, and the mastery criteria. Assessment informs those plans, so if you have not yet read the Area B guide (Behavior Assessment), start there.

C.1 Implement positive and negative reinforcement procedures

Reinforcement is any consequence that increases the future likelihood of the behavior it follows. Positive reinforcement adds something after the behavior: praise, a token, a snack, access to a toy. Negative reinforcement removes or reduces something after the behavior: taking away a demand, ending a loud noise, allowing a break. Both increase behavior. The word “negative” describes subtraction, not punishment, and this is one of the most tested distinctions on the exam.

The 3rd edition asks you to deliver reinforcement in a specific way:

• Immediately: the reinforcer should follow the behavior right away, ideally within a second or two. Delay weakens the connection and risks reinforcing whatever happened in between.
• Contingently: the reinforcer is delivered only when the target behavior occurs, and not when it does not. If the client gets the item anyway, the behavior has no reason to change.
• On the planned schedule: a continuous schedule (every correct response is reinforced) is typical when a skill is new. Intermittent schedules (only some responses are reinforced) build persistence and are used once the skill is established. Follow the schedule in the plan; do not thin it on your own.
• Across magnitude, intensity, and variety: bigger or more enthusiastic reinforcers for harder or newly emerging responses, and a rotating menu of reinforcers so no single one loses its value through satiation.

A common mistake is accidentally reinforcing problem behavior, for example giving a break when the client yells during a demand. That is negative reinforcement of yelling. Always pair reinforcement with the target behavior and deliver it immediately.

Session example: The plan uses a continuous schedule for a new tacting program. Each time the client correctly labels a picture, you deliver enthusiastic praise and a small piece of a preferred snack within one second, and you vary the praise statements across trials.

Check yourself

1. A client is working on a puzzle and says “help.” The RBT immediately removes the two hardest pieces from the task. Over the next week, the client says “help” more often during puzzles. Which process is this?

A. Positive reinforcement
B. Negative reinforcement
C. Positive punishment
D. Extinction

Answer: B. Removing part of the demand after the request increased the future frequency of the request, which is negative reinforcement.

2. A plan states that a client’s correct responses should be reinforced on a continuous schedule. The RBT decides the client “has it” and starts reinforcing every third response during the same session. What is the problem?

A. Nothing, because intermittent schedules are always better
B. The RBT changed the schedule without the supervisor’s approval, which is a fidelity error
C. Continuous reinforcement is never used for new skills
D. The client should have been given a break instead

Answer: B. Schedule changes are the analyst’s decision; thinning without approval departs from the written plan and can slow acquisition.

C.2 Establish and use conditioned reinforcers

Unconditioned (primary) reinforcers, such as food, water, and warmth, work without any learning history. Conditioned (secondary) reinforcers, such as praise, tokens, points, and attention, only become reinforcing through pairing with reinforcers that already work. The 3rd edition asks RBTs not only to use conditioned reinforcers but to help establish them.

Establishing a conditioned reinforcer is a pairing procedure. You present the neutral stimulus, for example the word “great,” a high five, or a token, immediately before or at the same time as an established reinforcer, many times. Over repeated pairings, the neutral stimulus starts to function as a reinforcer on its own. The same logic is how an RBT becomes reinforcing to a new client: during the first sessions you pair yourself with preferred items and activities, delivering them freely, before placing demands.

Conditioned reinforcers are practical because they can be delivered instantly, they rarely satiate, and they bridge the gap between a behavior and a delayed reinforcer. A token delivered the moment a response occurs keeps the connection tight even if the backup reinforcer comes minutes later. Generalized conditioned reinforcers, such as tokens or money, are paired with many different backup reinforcers, so they keep working regardless of what the client wants at the moment.

Conditioned reinforcers can also lose their value. If tokens are handed out without ever being exchanged, or praise is never paired with anything the client cares about, the pairing breaks down. Keep the backup exchange reliable and re-pair when needed.

Session example: With a new client, you spend the first two sessions handing over preferred toys and snacks while saying “nice work” each time, so that the phrase begins to function as a reinforcer before you introduce teaching trials.

Check yourself

1. An RBT wants a thumbs-up gesture to work as a reinforcer for a client who currently only responds to snacks. What should the RBT do?

A. Use the thumbs-up alone and wait for it to become reinforcing
B. Deliver the thumbs-up immediately followed by a snack across many trials
C. Withhold snacks until the client accepts the thumbs-up
D. Replace snacks with tokens right away

Answer: B. Repeatedly pairing the neutral gesture with an established reinforcer is how a conditioned reinforcer is created.

2. Why are tokens described as generalized conditioned reinforcers?

A. They are reinforcing at birth
B. They can be exchanged for many different backup reinforcers, so they do not depend on one specific deprivation
C. They only work in classrooms
D. They must be delivered on a continuous schedule

Answer: B. Pairing with a wide range of backups is what makes a conditioned reinforcer generalized and resistant to satiation.

C.3 Implement discrete-trial teaching procedures

Discrete-trial teaching (DTT) is a highly structured format that breaks learning into small, repeated units. Each trial has a clear beginning and end and consists of an instruction or discriminative stimulus (SD) such as “Touch your nose,” a response from the client, and a consequence. Correct responses earn reinforcement. Incorrect responses or no response lead to an error correction procedure written in the plan, often a prompt followed by another opportunity. A brief intertrial interval separates one trial from the next.

A DTT session for color identification might involve ten trials of “What color is this?” using red, blue, and green cards. The RBT provides a prompt if the client does not respond or responds incorrectly, delivers reinforcement for a correct or prompted response as the plan specifies, and records the result of every trial. Across sessions prompts are faded and independent responding increases.

Tips for effective DTT:

• Use clear, concise instructions and give the SD only once.
• Secure the client’s attention before presenting the SD.
• Deliver reinforcement immediately and enthusiastically.
• Record data in real time, trial by trial.
• Follow the error correction procedure exactly and keep your reaction to errors neutral.

The most common errors are repeating the SD several times, which teaches the client to wait for the third instruction, and delivering inconsistent prompts or reinforcement, which muddies the learning. DTT builds foundational skills quickly, and the exam expects you to know its parts, its strengths, and how it differs from naturalistic teaching in C.4.

Session example: You say “touch red” once, wait three seconds, and when the client touches the red card you say “yes, red!” and hand over a token, mark a plus on the data sheet, and pause briefly before the next trial.

Check yourself

1. Which sequence correctly describes one discrete trial?

A. Reinforcement, response, instruction
B. Instruction, response, consequence, intertrial interval
C. Prompt, reinforcement, data collection
D. Response, instruction, consequence

Answer: B. A discrete trial begins with the SD, is followed by the response and the consequence, and ends with a short pause before the next trial.

2. During DTT, the client does not respond to “touch blue.” The RBT repeats “touch blue” three more times, louder each time. What is the concern?

A. None; repetition helps the client hear
B. Repeating the SD teaches the client to wait for multiple instructions and departs from the error correction procedure
C. The RBT should have delivered reinforcement anyway
D. The trial should count as correct

Answer: B. The SD should be given once, and no response should trigger the plan’s error correction procedure rather than repeated instructions.

C.4 Implement naturalistic teaching procedures

Naturalistic teaching, which includes incidental teaching and natural environment training (NET), embeds learning opportunities into everyday activities and client-led interactions. Instead of the RBT choosing the materials and the timing, the client’s own interest sets the occasion. The reinforcer is the thing the client already wanted, which makes the teaching moment meaningful and helps the skill transfer to real life.

For example, if a child reaches for a toy truck, the RBT might hold it and prompt “truck” or “I want truck” before handing it over. The request produces the truck, so the natural consequence does the reinforcing. In incidental teaching specifically, the RBT arranges the environment so that interesting items are visible but slightly out of reach, waits for the client to initiate, prompts an elaborated response, and then delivers the item.

RBTs using naturalistic teaching must:

• Watch for what the client is interested in right now.
• Wait for, or gently arrange, naturally occurring teaching moments.
• Prompt only as much as needed and fade quickly.
• Reinforce with the natural consequence, immediately.
• Still collect data, even though the setting is informal.

Mistakes to avoid include over-prompting until the interaction turns into a DTT drill, missing teachable moments because you are focused on materials or data sheets, and using reinforcers that do not fit the activity. Naturalistic teaching is especially useful for early language, play, and social skills, and for promoting generalization, because the skills are learned where they will actually be used.

Session example: During block play you keep the blocks in a clear bin with the lid on. When the client looks at the bin, you model “open” and, as soon as the client says “open,” you open the lid and hand over a block.

Check yourself

1. Which scenario is the clearest example of incidental teaching?

A. The RBT presents ten flashcards at the table and reinforces each correct label with a token
B. The client reaches toward bubbles on a shelf; the RBT waits, prompts “bubbles,” and blows bubbles when the client says it
C. The RBT delivers a token for sitting quietly during a video
D. The RBT runs a preference assessment before the session

Answer: B. The client initiated, the RBT prompted an elaboration, and the natural consequence (bubbles) reinforced the response.

2. What is the main difference between DTT and naturalistic teaching?

A. Naturalistic teaching does not use reinforcement
B. DTT is client-led and naturalistic teaching is RBT-led
C. DTT is structured and RBT-initiated; naturalistic teaching follows the client’s interest and uses natural consequences
D. Data are only collected in DTT

Answer: C. Both use reinforcement and data collection; they differ in who initiates and how structured the trials are.

C.5 Implement task-analyzed chaining procedures

Many important skills, such as hand washing, dressing, or making a sandwich, are chains of smaller behaviors performed in order. A task analysis breaks the chain into teachable steps, and chaining is the set of procedures for teaching those steps until the client can do the whole sequence independently. The 3rd edition names three methods:

• Forward chaining: teach the first step first. The client performs step one and the RBT completes the rest. Once step one is mastered, the client performs steps one and two, and so on. Reinforcement follows the client’s completed step.
• Backward chaining: the RBT completes or guides all steps except the last, and the client performs the final step, which is reinforced by finishing the task. Once the last step is mastered, the client also performs the second-to-last step, working backward. Because the client always experiences the natural end of the task, backward chaining is often chosen when finishing the task is itself rewarding.
• Total task chaining: the client attempts every step in every session, with prompts on whichever steps need them. It suits clients who can already do many of the steps.

Example with tooth brushing: forward chaining teaches “pick up toothbrush” first; backward chaining has the RBT guide everything up to “rinse and spit,” which the client does independently; total task has the client work through all steps with help where needed.

Always follow the written task analysis, use the prompting and fading procedures the plan specifies, and record data step by step so the analyst can see exactly which steps are independent. Common mistakes are deviating from the step order and helping too much, which leads to prompt dependence.

Session example: Using backward chaining for hand washing, you guide the client through turning on the water, wetting hands, applying soap, scrubbing, and rinsing, then remove your hands so the client independently turns off the faucet and dries, and you deliver praise as the towel goes back on the hook.

Check yourself

1. An RBT physically guides a client through every step of putting on a coat except the final step of pulling up the zipper, which the client does alone and is praised for. Which chaining method is this?

A. Forward chaining
B. Backward chaining
C. Total task chaining
D. Shaping

Answer: B. The client independently performs the last step while the RBT completes the earlier ones, which is backward chaining.

2. A client can already do most of the steps in a lunch-packing routine but needs help with two of them. Which method is most likely to be chosen?

A. Total task chaining
B. Backward chaining only
C. Forward chaining only
D. Free operant assessment

Answer: A. Total task chaining has the client attempt all steps each time, with prompts only on the steps that need them.

C.6 Implement discrimination training

Discrimination training teaches a client to respond to one stimulus and not to others. It is how learners come to recognize letters, follow specific instructions, tell a cat from a dog, or greet a familiar person but not a stranger. The mechanism is differential reinforcement: responses in the presence of the discriminative stimulus (SD) are reinforced, and responses in the presence of other stimuli (S-delta) are not.

A basic setup looks like this: the SD “Touch red” is given, a red card and a blue card are on the table, and only touching the red card produces reinforcement. Touching blue produces no reinforcement and triggers the error correction procedure. Over many trials, the red card comes to control the response.

RBTs implement discrimination training using:

• Errorless teaching in the early stages, prompting the correct choice so the client rarely practices errors.
• Prompt fading as accuracy improves (see C.7).
• Random rotation of targets and positions so the client is not simply picking the left card or the newest card.
• Mixing mastered targets with new ones to keep the client engaged and to check that earlier discriminations still hold.

Mistakes to avoid are giving unclear or inconsistent SDs, accidentally reinforcing an incorrect response, and always presenting the target in the same position. Discrimination training is foundational for academic, communication, and safety skills, and the exam often tests whether you can identify the SD and the S-delta in a scenario.

Session example: Teaching the label “dog,” you present a dog picture and a cat picture, say “touch dog,” reinforce touching the dog, and on the next trial move the dog picture to the other side so position does not give the answer away.

Check yourself

1. In a program where “Touch cup” is followed by reinforcement only when the client touches the cup and not the spoon, what is the spoon?

A. The discriminative stimulus
B. The S-delta
C. The reinforcer
D. The prompt

Answer: B. The stimulus in whose presence a response is not reinforced is the S-delta.

2. A client correctly selects the target card only when it is on the left side of the table. What should the RBT check first?

A. Whether the reinforcer is still preferred
B. Whether target positions have been rotated across trials
C. Whether the client needs a longer intertrial interval
D. Whether the session is too short

Answer: B. Consistent placement lets position, not the SD, control the response, so rotation is the first thing to fix.

C.7 Implement stimulus and response prompts with fading

A prompt is extra help that makes a correct response more likely while a skill is being learned. The 3rd edition splits prompts into two kinds. Response prompts act on the learner’s behavior: physical guidance, modeling, gestures, and verbal prompts. Stimulus prompts act on the materials: making the correct card larger, placing it closer, or highlighting it so it stands out. Either way, the goal is to transfer control from the prompt to the natural SD so the client responds independently.

Fading is the systematic removal of prompts. The 3rd edition names four approaches:

• Errorless learning: begin with a prompt strong enough to guarantee a correct response, then fade it gradually. The client rarely practices errors, which is useful for new or frustrating skills.
• Least-to-most prompting: give the SD and wait. If the client does not respond, add the least intrusive prompt, then a stronger one, until the response occurs. This gives the client a chance to respond independently on every trial.
• Stimulus fading: gradually change the materials, for example shrinking an enlarged target card back to normal size, until the natural stimulus alone controls the response.
• Time delay: insert a pause between the SD and the prompt. Start with zero delay (prompt immediately), then wait progressively longer, so the client learns to respond before the prompt arrives.

Most-to-least prompting, which starts with full guidance and steps down, is also common. Fade too quickly and errors and frustration climb; fade too slowly and the client becomes prompt dependent. Use exactly the prompt level and fading step written in the plan, keep prompts consistent across staff, and reinforce independent responses more richly than prompted ones so independence pays off. Replacement behaviors in Area D (Behavior Reduction) are taught with the same prompting and fading tools.

Session example: Teaching a child to answer “What’s your name?”, you begin by whispering the name at the same time as the question, then wait two seconds before whispering, then four seconds, until the child answers before any prompt is given.

Check yourself

1. An RBT places the correct answer card closer to the client than the distractor cards and gradually moves it back into line over sessions. Which procedure is this?

A. Time delay
B. Stimulus fading
C. Least-to-most response prompting
D. Backward chaining

Answer: B. Altering the materials themselves and then gradually restoring them to normal is stimulus fading.

2. The plan says to give the SD, wait five seconds, then provide a gestural prompt, and if that fails, a partial physical prompt. Which prompting approach is this?

A. Most-to-least
B. Errorless
C. Least-to-most
D. Total task

Answer: C. Starting with no prompt and adding progressively more intrusive help only as needed is least-to-most prompting.

C.8 Implement generalization procedures

A skill is not really learned until the client can use it outside the teaching session. Generalization means the behavior occurs across settings, with different people, and in response to different but related stimuli, without having been directly taught in every one of those situations. The 3rd edition names three dimensions: across settings (therapy room, classroom, home, community), across people (RBT, parent, teacher, peer), and across stimuli (different cups, different dogs, different ways of asking the same question).

Generalization does not happen on its own. RBTs promote it deliberately by:

• Teaching with multiple examples: several different cups, several people asking, several settings.
• Varying materials, instructions, and reinforcers during teaching so the skill is not tied to one arrangement.
• Practicing in the natural environment, and reinforcing the skill when it appears there.
• Involving caregivers and teachers so the skill is prompted and reinforced by people other than the RBT.
• Running generalization probes, which test the skill with new materials or people without teaching first, and recording the results.

Response generalization is a related idea: the client produces different responses that serve the same purpose, such as waving or saying “hi” to greet. Programs may target it specifically.

The classic mistake is teaching a skill in one context, with one set of materials, and assuming it will transfer. If a client only says “juice” to the RBT in the therapy room, the skill has not generalized, and the analyst needs to know.

Session example: After the client masters requesting “ball” with one red ball in the clinic, you probe the skill on the playground with a blue ball and a peer, and record whether the request occurs without prompting.

Check yourself

1. A client labels a picture of a golden retriever as “dog” but does not label a picture of a small terrier. Which kind of generalization has not yet occurred?

A. Across settings
B. Across people
C. Across stimuli
D. Maintenance

Answer: C. Responding the same way to different examples of the same category is stimulus generalization.

2. Which strategy is most likely to promote generalization of a greeting skill?

A. Teaching it only with the RBT until 100% accuracy is reached
B. Practicing with several different people and in several settings, and reinforcing greetings that occur naturally
C. Using the same script every time
D. Removing all reinforcement once the skill is mastered

Answer: B. Multiple examples across people and settings, with reinforcement in the natural environment, is the core of generalization programming.

C.9 Distinguish maintenance from acquisition procedures

Acquisition is the phase in which a client is learning a new skill. Maintenance is the phase after mastery, when the goal is for the skill to keep occurring over time without ongoing teaching. The 3rd edition asks RBTs to tell the two apart, because they are run differently and the data are interpreted differently.

During acquisition, teaching is intensive. The plan typically specifies a dense reinforcement schedule (often continuous), prompting and fading, frequent trials, error correction, and trial-by-trial data. Mastery criteria, such as 90% correct across three consecutive sessions, mark the end of acquisition.

During maintenance, the skill is no longer being taught. It is checked. Maintenance probes present the mastered target periodically, often with no prompts, on a thinner or natural reinforcement schedule, and the RBT records whether the response still occurs. If a maintenance probe fails, the target may go back into acquisition, but that decision belongs to the analyst.

Why the distinction matters in practice: before each session, review which targets are in acquisition and which are in maintenance. Running a maintenance target with full acquisition procedures wastes teaching time and can make the client prompt dependent again. Running an acquisition target as a maintenance probe, with no prompts and little reinforcement, exposes the client to repeated failure. Data from the two phases should also be kept separate on the graph, because a maintenance score answers a different question than an acquisition score.

Maintenance and generalization are related but different. Generalization asks whether the skill occurs in new situations; maintenance asks whether it lasts over time.

Session example: Your session sheet lists “tacts animals” as a maintenance target. You present five animal cards once each, with no prompts and only occasional praise, record 5 out of 5, and move on to the acquisition targets that get the full teaching procedure.

Check yourself

1. A target was mastered two months ago. The RBT now presents it once a week with no prompts and records whether the client still responds correctly. What is this called?

A. Acquisition trial
B. Maintenance probe
C. Preference assessment
D. Stimulus fading

Answer: B. Periodically checking a mastered skill over time, without teaching, is a maintenance probe.

2. An RBT runs a target that is still in acquisition using no prompts and a thin reinforcement schedule “to see if the client can do it.” What is the concern?

A. None, since this saves time
B. Acquisition targets need the teaching procedure in the plan; treating them as maintenance probes leads to errors and lost learning
C. Maintenance targets should never be probed
D. The RBT should use a punishment procedure instead

Answer: B. Acquisition and maintenance procedures differ on prompting and reinforcement, and the RBT must run each target according to its current phase in the plan.

C.10 Implement shaping procedures

Shaping is used when the target behavior does not yet occur at all, or occurs in a form too rough to reinforce directly. Instead of waiting for the perfect response, you reinforce successive approximations, that is, responses that come progressively closer to the final behavior, while stopping reinforcement for earlier, cruder forms.

Example: a child who is nonverbal may first be reinforced for making any vocalization when reaching for a ball. Once vocalizing is reliable, only sounds that resemble “ba” are reinforced. Later, only “ball” earns the ball. Each shift in the criterion moves the behavior closer to the goal.

Steps in shaping:

• Define the terminal behavior precisely, for example saying “ball.”
• Identify a starting behavior the client already does that resembles it, even loosely.
• Reinforce that approximation until it is consistent.
• Raise the criterion to a closer approximation and reinforce only that, allowing the earlier form to go unreinforced.
• Continue until the terminal behavior occurs.

Shaping requires patience and timing. Reinforcement must follow the approximation immediately, and it must stop for the old form as soon as the criterion moves. Raise the criterion too fast and the behavior may fall apart; leave it too long and progress stalls. The analyst sets the approximations and decides when to move to the next one; the RBT implements each step and reports how the client is responding.

Shaping differs from chaining: chaining teaches a sequence of distinct steps, while shaping refines the form of a single response. It differs from prompting because no extra help is added; the behavior is built entirely through what gets reinforced.

Session example: Working on the client’s grip on a pencil, the current criterion is any three-finger grasp. You reinforce each attempt that meets it and withhold reinforcement for a fist grip, and you note in the data that the client met the criterion on most trials so the supervisor can decide whether to move to the next approximation.

Check yourself

1. An RBT first reinforces a client for looking toward a peer, then only for looking and waving, then only for looking, waving, and saying “hi.” Which procedure is this?

A. Backward chaining
B. Shaping
C. Discrimination training
D. Stimulus fading

Answer: B. Reinforcing progressively closer approximations of the final greeting is shaping.

2. During shaping, the client has met the current approximation reliably for several sessions but the RBT keeps reinforcing it. What is the likely effect?

A. The behavior will move to the next approximation on its own
B. Progress toward the terminal behavior stalls because the criterion has not been raised
C. The client will stop responding entirely
D. The client will generalize the skill

Answer: B. Shaping depends on shifting the criterion; continuing to reinforce a mastered approximation holds the behavior in place.

C.11 Implement token economy procedures

A token economy is a system in which the client earns tokens for specified behaviors and later exchanges them for backup reinforcers such as toys, breaks, or snacks. Tokens are generalized conditioned reinforcers (see C.2), so a working token economy depends on tokens having been paired with things the client values.

Components of a token economy:

• Tokens: stickers, stars, points, chips, or checkmarks that can be delivered instantly.
• Target behaviors: the specific responses that earn tokens, written in observable terms.
• Backup reinforcers: the items or activities tokens can buy, ideally chosen from a recent preference assessment.
• Exchange schedule: how many tokens are needed and when exchange happens.

Example: a client earns one token for each completed worksheet. After five tokens, the client chooses between tablet time, a snack, or extra play.

RBT responsibilities include explaining the system in a way the client understands, delivering tokens immediately and consistently after the target behavior, keeping the exchange reliable so tokens stay valuable, monitoring and documenting progress, and checking that the backup reinforcers still motivate the client.

Mistakes to avoid: giving tokens for behavior that is not on the list, forgetting to follow through with the exchange, and changing the number of tokens required without supervisor approval. Removing tokens as a consequence for problem behavior (response cost) is a punishment procedure and must only be used if the plan specifically includes it.

Token economies are common in classrooms, groups, and homes because they let one reinforcement system cover many behaviors, bridge delays to the backup reinforcer, and make expectations clear.

Session example: The client’s token board has five spaces. Each time the client completes a step of the morning routine independently, you place a star on the board and say “star for brushing teeth,” and when the fifth star goes on you immediately offer the choice of backup reinforcers.

Check yourself

1. A client earns tokens for completing math problems and exchanges them for a preferred activity, but lately seems uninterested in earning them. What should the RBT check first?

A. Whether the backup reinforcers are still preferred and whether exchanges have been happening reliably
B. Whether the tokens are the right color
C. Whether the client should be punished for not working
D. Whether to double the number of tokens required

Answer: A. Tokens keep their value only through reliable exchange for reinforcers the client currently wants.

2. An RBT takes two tokens away when the client throws materials. The plan does not mention removing tokens. What is the issue?

A. There is no issue, since tokens belong to the RBT
B. Removing tokens is a response cost (punishment) procedure that requires the plan to include it
C. Tokens should be removed only for correct responses
D. The RBT should have removed all the tokens

Answer: B. Response cost is a punishment procedure, and RBTs implement only the procedures written in the plan.

How this area is tested

Area C is the largest area on the exam, and its questions are almost all scenarios: a short description of what an RBT did or is about to do, followed by “which procedure is this?” or “what should the RBT do?” Many questions describe two or three procedures in one scenario, so read for the exact detail that separates them. The 2nd edition tasks on identifying the parts of a written plan and preparing for sessions are no longer listed separately, but they still show up inside scenarios, so know what a plan contains and review it before every session.

Common traps:

• Negative reinforcement versus punishment. Negative reinforcement removes something and increases behavior; punishment decreases behavior.
• Forward versus backward chaining. Look at which step the client performs independently: first or last.
• Shaping versus chaining. Shaping refines one response; chaining builds a sequence.
• Shaping versus prompting. Shaping adds no help; prompting does.
• Stimulus prompt versus response prompt. Does the change apply to the materials or to the learner’s behavior?
• Least-to-most versus most-to-least. Which prompt level comes first?
• DTT versus naturalistic teaching. Who initiates, and is the reinforcer natural or arbitrary?
• Generalization versus maintenance. New situations versus time since mastery.
• Any option in which the RBT changes the schedule, criterion, prompt level, or token ratio without supervisor approval is wrong.

Practice this area

Take the Area C practice test to work through scenario questions on reinforcement, prompting, DTT, chaining, shaping, and token economies. Look up any unfamiliar term in the RBT exam glossary. Because the same reinforcement and prompting skills are used to teach replacement behaviors, continue to the Area D guide (Behavior Reduction) next.

Frequently asked questions

How many exam questions come from Area C?
19 of the 75 scored questions, or 25%. It is the largest area, so it deserves the biggest share of your study time.

What changed from the 2nd edition Skill Acquisition domain?
The name changed to Behavior Acquisition and the list went from twelve tasks to eleven. The separate tasks on plan components and session preparation were dropped, stimulus control transfer and prompt fading were merged into one prompting task, and new tasks were added on positive and negative reinforcement, establishing conditioned reinforcers, and distinguishing maintenance from acquisition.

Is negative reinforcement the same as punishment?
No. Negative reinforcement removes something and makes the behavior more likely in the future. Punishment makes the behavior less likely. The words positive and negative refer only to adding or removing a stimulus.

When should I use errorless teaching versus least-to-most prompting?
Whenever the plan says so. As a general pattern, errorless teaching is common for brand-new or frustrating skills where errors should be minimized, and least-to-most is common when the client already has some of the skill and needs a chance to respond independently.

Can an RBT decide to move a target from acquisition to maintenance?
No. The supervising analyst applies the mastery criteria and changes the target’s status. The RBT runs each target according to its current phase and reports the data.

What is the difference between a token economy and simple reinforcement?
In simple reinforcement, the reinforcer itself follows the behavior. In a token economy, a token follows the behavior immediately and is later exchanged for the reinforcer, which lets the RBT reinforce many behaviors quickly and bridge delays.
