An RBT is helping a BCBA run a curriculum-based skills assessment with a 5-year-old client. The written protocol says to present each item once and record whether the client responds correctly and independently. On a labeling item, the client looks at a picture of a dog but says nothing for several seconds. What should the RBT do?

Preference assessments, skill assessments and your part in functional assessment.
What the RBT exam tests in Behavior Assessment
- Run preference assessments: multiple stimulus (with/without replacement), paired stimulus, free operant
- Take part in assessing skill strengths and deficits: curriculum-based, developmental, social-skills assessments
- Take part in parts of functional assessment: indirect and descriptive (ABC) assessment, functional analysis
High-yield behavior assessment facts
- Preference is not proof of reinforcement. A reinforcer assessment tests whether contingent delivery actually increases behavior.
- Preferences shift with motivating operations (deprivation, satiation). Run brief preference checks often, for example before sessions.
- Skill assessments (curriculum-based, developmental, adaptive, social-skills): the RBT helps collect data. The supervisor selects the tool, interprets results and writes goals.
- Indirect assessment = asking people: interviews and rating scales with caregivers and teachers.
- Descriptive assessment = watching: direct observation in the natural setting, usually ABC recording written objectively.
- Functional analysis (FA) = deliberately arranging conditions to test what maintains behavior. Typical conditions are attention, demand/escape, alone/ignore, tangible, and play (control).
| Type | Procedure | Key point |
|---|---|---|
| Free operant | Free access to many items; record time with each | Nothing is removed, so least likely to trigger problem behavior |
| Single stimulus | One item at a time; record approach or engagement | For learners who can't choose between items |
| Paired stimulus (forced choice) | Two items at a time; every item paired with every other | Produces a ranking but takes longer |
| MSW (with replacement) | Array; chosen item goes back into the array | The same favorite may be picked repeatedly |
| MSWO (without replacement) | Array; chosen item is removed; repeat with the rest | Quick preference hierarchy |

Common behavior assessment traps
- MSW returns the chosen item; MSWO removes it.
- Indirect = ask, descriptive = watch, FA = manipulate conditions.
- A highly preferred item may still fail to function as a reinforcer.
- The RBT does not decide the function or write goals; that is the supervisor's job.
- ABC notes with opinions ('was jealous') are not objective descriptive data.
Free RBT behavior assessment practice questions
Question 1
During ABC data collection at a school, a client throws a block after his teacher speaks to him. Which antecedent entry is written most appropriately?
- ATeacher seemed annoyed and made the client feel frustrated
- BClient wanted to keep playing because he was in a bad mood
- CTeacher said "Clean up the blocks" and held out the bin
- DClient became aggressive as usual during cleanup time
Show answer and explanation
Answer: C. This is an objective, observable description of exactly what occurred right before the behavior.
Why not A: This describes inferred emotions rather than observable events, so another observer could not verify it.
Why not B: This guesses at the client's motives and mood instead of describing what actually happened in the environment.
Why not D: This uses a vague label and a judgment ("as usual") rather than describing the specific event that came before the behavior.
Remember: ABC entries must describe observable, measurable events, not feelings, motives, or labels.
Question 2
A BCBA asks an RBT to help with an assessment. The RBT checks whether a 3-year-old can stack blocks, use two-word phrases, and jump with both feet. Each skill is compared with the age at which typically developing children usually show it. Which type of assessment is this?
- ASocial-skills assessment
- BIndirect functional assessment
- CDevelopmental assessment
- DFree operant preference assessment
Show answer and explanation
Answer: C. Developmental assessments compare a learner's skills with milestones typically reached at certain ages across areas such as motor, language, and self-help.
Why not A: A social-skills assessment focuses on interactions with others. These items cover motor and language milestones.
Why not B: Indirect functional assessments use interviews or rating scales about problem behavior. They do not compare skills to age milestones.
Why not D: Preference assessments identify potential reinforcers. They do not measure skill milestones.
Remember: Developmental assessments compare a learner's skills to the typical ages at which milestones emerge.
Question 3
A client reliably screams and hits whenever a preferred item is taken away. The BCBA asks the RBT to run the preference assessment format least likely to trigger this behavior. Which format best fits?
- AMultiple-stimulus-without-replacement assessment
- BPaired-stimulus assessment
- CMultiple-stimulus-with-replacement assessment
- DFree-operant assessment
Show answer and explanation
Answer: D. In a free-operant assessment all items stay available and the RBT records engagement time, so no items are withdrawn.
Why not A: MSWO requires taking back each selected item after brief access, so it repeatedly involves item removal.
Why not B: Paired-stimulus trials repeatedly present items and then remove them, which would often produce the removal-related problem behavior.
Why not C: MSW still takes the chosen item back after brief access before the next trial, so it does not avoid item removal.
Remember: Free-operant preference assessments avoid withdrawing items, making them useful for clients whose problem behavior is evoked by item removal.
Question 4
An RBT is helping with a curriculum-based skills assessment. She places three pictures on the table and says, "Touch dog." The client looks away and does not respond. According to standard assessment procedures, what should the RBT do?
- AScore the item as mastered because the parent says the client knows dogs
- BRepeat the instruction and offer candy until the client touches the dog
- CRecord that the skill was not shown and continue with the next item
- DPhysically guide the client's hand to the dog and score the item correct
Show answer and explanation
Answer: C. Assessment probes measure what the client can do independently, so the RBT records the response as the protocol directs without teaching or prompting.
Why not A: The RBT should record directly observed performance during the assessment, not a secondhand report.
Why not B: Repeated instructions and added reinforcement turn the probe into teaching and distort the assessment results.
Why not D: A prompted response does not show an independent skill, so scoring it correct would overestimate the client's abilities.
Remember: Skill assessment probes measure independent performance, so do not prompt or teach during them unless the protocol says to.
Question 5
A learner sees 7 items in a row and picks a toy car. After brief access, the RBT returns the car to the row, rearranges the items, and presents the full array again. The car stays available on every trial. Which assessment is this?
- AMultiple stimulus with replacement
- BMultiple stimulus without replacement
- CPaired stimulus
- DFree operant
Show answer and explanation
Answer: A. The chosen item is put back into the array, so it can be chosen again on later trials.
Why not B: In MSWO the chosen car would be left out of later trials, so the array would shrink each time.
Why not C: Paired stimulus shows only two items per trial, not an array of 7.
Why not D: Free operant gives open access with no selection trials. Here the learner makes discrete choices from an array.
Remember: With replacement means the selected item goes back into the array; without replacement means it is removed from later trials.
