What Domain E covers
Domain E covers ethical and professional decision-making, including competence, informed consent, confidentiality, documentation, supervision, conflicts, and responsibility to clients and stakeholders.
The BACB 6th Edition Test Content Outline assigns Domain E 22 scored questions, or 13% 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 supervisor is asked to approve a plan in an unfamiliar specialty before reviewing the assessment or receiving training. The defensible next step is to acknowledge the competence boundary, obtain consultation or training, document the decision process, and protect the client's continuity of care.
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.
