The field of applied behavior analysis (ABA) continues to evolve, and so do the expectations for behavior analysts. To ensure certification exams reflect current best practices, the Behavior Analyst Certification Board (BACB) has released the 6th Edition Test Content Outline (TCO), which will be implemented for exams starting January 1, 2025. This update replaces the 5th edition and introduces several important revisions that future BCBAs should understand.

Retention and Refinement of Content Domains

The new task list retains nine content domains, consistent with the 5th edition. However, four domain titles have been updated for clarity. The content within each domain has been reorganized to improve logical flow, eliminate redundancies, and help candidates study more effectively. To prepare strategically, review our top BCBA exam preparation resources.

Clearer Task Statements with Purposeful Language

Many task statements have been revised to use more intentional and descriptive verbs, helping candidates better understand the skills and actions expected of a certified behavior analyst. This improvement aims to enhance learning outcomes and practical application. For further guidance, explore our BCBA exam format and preparation tips.

Ethics Domain Redefined

One of the most significant updates is the restructuring of the Ethics domain. Formerly a general reference to the BACB’s Ethics Code, this domain is now titled “Ethical and Professional Issues” and includes 12 specific tasks. This targeted approach helps candidates focus on concrete expectations for ethical decision-making and professional conduct. You can learn more about these expectations in our article on BCBA supervision requirements and professional standards.

Inclusion of Diversity, Equity, and Inclusion (DEI)

The 6th edition task list now integrates diversity, equity, and inclusion across six tasks in three domains. This shift highlights the growing importance of cultural competence in ABA and promotes the delivery of services that are respectful and responsive to clients from diverse backgrounds.

Task List Overview: Net Increase and Streamlining

The total number of tasks has increased to 104, reflecting the addition of 13 new tasks. Meanwhile, 9 tasks were removed, and 10 were consolidated into 5, resulting in a more efficient structure with minimal redundancy.

New Tasks Introduced in the 6th Edition

The following tasks have been newly added to address emerging priorities in ABA:

• B.20 Understand the role of multiple control in verbal behavior
• B.22 Use behavioral momentum to analyze response persistence
• B.23 Apply the matching law to interpret behavior
• B.24 Distinguish imitation from observational learning
• C.12 Choose appropriate measurement procedures for procedural integrity
• D.3 Identify threats to internal validity
• D.6 Analyze single-case experimental design data
• E.2 Recognize risks of unethical behavior to self and profession
• E.8 Use interpersonal skills to support professional relationships
• F.2 Consider cultural variables during assessments
• G.18 Evaluate emotional effects of behavior-change procedures
• H.5 Anticipate and address behavior relapse
• I.3 Promote equity in supervision practices

These additions reflect current trends and demands in the profession, better preparing candidates for real-world scenarios. For guidance on how to structure your study sessions effectively, see our step-by-step BCBA exam scheduling guide.
