Free RBT Behavior Assessment Quiz 2026 | 25 Questions (Task List 3.0)
In Applied Behavior Analysis (ABA), we cannot effectively teach new skills or reduce problem behaviors unless we understand the client first. This is where Domain B: Assessment comes in.
If you are preparing for the RBT exam (3rd Edition), you must understand how to identify what a client likes (Preference Assessments) and why a behavior is happening (Functional Assessment).
This guide breaks down the critical concepts of assessment and provides a free interactive practice quiz to test your readiness.
RBT Domain B: Assessment
Assessment Objective:
- 25 Questions on Assessment Procedures
- Focus on Preference Assessments & ABC Data
- Passing requirement: 80%
Assessment Summary
The Role of the RBT in Assessment
It is important to remember your scope of practice. As an RBT, you do not design assessments or diagnose clients. Your role is to assist.
- BCBA’s Role: Selects the assessment and analyzes the data.
- RBT’s Role: Conducts observations, runs trial-based assessments, and collects accurate data.
1. Preference Assessments
Before we can teach a skill, we need to know what motivates the learner. A “Preference Assessment” identifies potential reinforcers.
Types of Preference Assessments:
- Free Operant: The client is allowed to freely explore the room. You simply observe and time how long they engage with each item. (Best for clients who engage in problem behavior when items are removed).
- Single Stimulus: Presenting one item at a time. (Good for clients who have trouble choosing between two things).
- Paired Stimulus (Forced Choice): Presenting two items and asking the client to “pick one.” This creates a hierarchy of most-to-least preferred items.
- Multiple Stimulus Without Replacement (MSWO): You present an array (e.g., 5 toys). When the client picks one, they get to play with it, and then it is removed from the next trial. This is a fast way to rank preferences.
- Multiple Stimulus With Replacement (MSW): Similar to MSWO, but the chosen item is put back into the array.
2. Functional Assessment Procedures
Why is the client screaming? Is it for attention? Escape? To answer this, we use Functional Assessments.
ABC Data (Antecedent-Behavior-Consequence)
This is the most common tool an RBT uses.
- Antecedent: What happened immediately before the behavior? (e.g., “The teacher said ‘cleanup'”).
- Behavior: What exactly did the client do? (Must be observable and measurable).
- Consequence: What happened immediately after? (e.g., “The teacher removed the demand”).
By collecting ABC data over time, the supervisor can hypothesize the Function of the behavior (Escape, Attention, Tangible, or Automatic).
Functional Analysis (FA)
This is an experimental procedure where the supervisor manipulates the environment to test why a behavior happens. RBTs assist by ensuring safety and collecting data, but the supervisor leads this process.
