What should be prepared before starting the session?

• A. Only the reinforcers.
• B. Materials for protocols, reinforcers, and data collection systems.
• C. Only data collection forms.
• D. Only the client's materials.

Answer: (B)

Preparing for a session means having everything you need to run the plan smoothly: the materials for the protocols you will follow, the reinforcers you will use to reinforce behavior, and the data collection system you’ll rely on to record outcomes. Without ready-to-use protocol materials, you can’t implement the procedures exactly as designed. Without reinforcers, you can’t maintain motivational contingencies. Without a data system, you may miss important data or make inaccurate decisions about progress. Having all three components ensures the session runs efficiently, the client receives consistent reinforcement, and you can track behavior accurately to guide future steps. Focusing on only one component—such as reinforcers, data forms, or client materials—ignores essential pieces needed for faithful implementation and effective decision-making.
