What Domain G covers
Domain G covers selecting and applying behavior-change procedures, including antecedent strategies, consequence procedures, skill acquisition, reduction, generalization, and maintenance.
The BACB 6th Edition Test Content Outline assigns Domain G 25 scored questions, or 14% of the exam. The percentage is an official exam weight; the study sequence below is editorial guidance.
Worked vignette
Reason through an original practice scenario
A learner uses a communication card to request a break during independent work. The team wants to increase appropriate requests and reduce task-avoidance behavior. A strong plan reinforces the functional request, teaches it across relevant contexts, and monitors whether the skill generalizes rather than relying only on a reduction graph.
This is an original study vignette written for this guide. It is not a BACB exam item and is not copied from Cooper, Heron, and Heward.
Five practice prompts
Practice Domain G without memorizing answer choices
Answer each prompt in writing, then explain what evidence would change your decision. These are prompts for study, not full exam items.
- Identify the likely function and the replacement response.
- Which antecedent change could make the replacement response easier to use?
- What consequence would strengthen the replacement response without creating an unsafe dependency?
- How would you program generalization across people and settings?
- What data would show that the procedure should be continued or changed?
This week
A focused Domain G study block
Review one acquisition procedure and one reduction procedure. Write the target response, teaching sequence, consequence, generalization plan, and decision rule. Finish with a mixed set that asks you to identify the mechanism of change.
For textbook concepts used here, consult Cooper, Heron, and Heward (2020) and verify current ethics or exam requirements against the BACB source documents.

How should I practice this domain?
Use the domain-intent practice link on this page, review why each answer is stronger than its distractors, and use a full mock later for pacing across all nine domains.
