RBT Competency Assessment: Behavior Reduction (2026)

Skills Assessed: Behavior Reduction

1. Implementing the Intervention Plan

Your assessor will give you a written Behavior Intervention Plan (BIP) and ask you to implement it with a client (or role-play scenario). You must follow the plan EXACTLY as written — RBTs do not design or modify plans, only implement them.

Example: The BIP says "After 3 prompt levels, if no response, provide error correction and record as incorrect trial." You must follow this sequence exactly. The assessor checks that you did not skip steps, modify the procedure, or add interventions not in the written plan. You are the implementer, not the designer.

2. Collecting Data During Intervention

While implementing the behavior reduction plan, you must collect accurate data on the target behavior and the intervention. This includes frequency of the problem behavior, whether the intervention was delivered correctly, and any notes on client response.

Example: You are implementing a DRO (Differential Reinforcement of Other behavior). You set a 5-minute timer — if the client goes 5 minutes without hitting, they get a token. You record: timer started at 10:00, client hit at 10:03 (timer reset), timer restarted at 10:03, no hitting until 10:08 (token delivered). The assessor checks your data matches what they observed.

3. Staying Calm During Problem Behavior

When a client engages in problem behavior (tantrum, aggression, self-injury), you must remain calm, follow the BIP, and not react emotionally. Your assessor is watching your demeanor as much as your technical skills.

Example: The client begins screaming and throwing materials. You calmly remove materials (extinction), set a timer for DRO, and continue to prompt the next task. You do NOT yell back, show frustration, or abandon the intervention. The assessor checks that you maintained professional calm throughout the episode and followed the BIP step-by-step.

Supervisor Competency Checklist (Behavior Reduction)

#	Task	Completed?	Notes
1	Implements Behavior Intervention Plan (BIP) exactly as written
2	Collects data on problem behavior during intervention
3	Collects data on intervention fidelity (was it delivered correctly?)
4	Stays calm during problem behavior (no emotional reaction)
5	Follows extinction procedure correctly (no accidental reinforcement)
6	Delivers reinforcement at correct interval (e.g., DRO timer)
7	Uses error correction as specified in the plan
8	Documents incident objectively (no opinions) if behavior escalates

Intervention Strategies

Strategy	What's Reinforced	Example
DRO (Differential Reinforcement of Other Behavior)	Any behavior OTHER than the problem behavior	Client goes 5 min without hitting → token. Timer resets if hitting occurs.
DRA (Differential Reinforcement of Alternative Behavior)	A specific appropriate behavior that replaces the problem behavior	Client asks "break please" (instead of screaming) → break granted. Reinforce the alternative.
DRI (Differential Reinforcement of Incompatible Behavior)	A behavior that is PHYSICALLY incompatible with the problem behavior	Client keeps hands in lap (incompatible with hitting) for 3 min → token. Cannot hit while hands are in lap.

Key difference: DRO = NO problem behavior → reinforce. DRA = specific alternative behavior → reinforce. DRI = incompatible behavior → reinforce.

Crisis Prevention: 3 Steps to Follow

Step 1: Ensure Safety — Remove dangerous objects, create space, ensure the client and others are physically safe. If the client is hitting others, guide them to a safer area. If self-injury occurs, block gently and remove harmful objects.

Step 2: Stay Calm — Do NOT yell, argue, or show frustration. Speak in a neutral, calm voice. Follow the BIP exactly. Emotional reactions escalate the crisis. Your calm demeanor models self-regulation for the client.

Step 3: Document the Incident — After the behavior ends, write an objective incident report. Include: date/time, antecedent (what happened before), behavior description (observable, measurable), consequence (what happened after), and witnesses. "Client screamed for 8 minutes after math worksheet presented" NOT "Client was mad about work."
