How is the BCBA Test Content Outline 6th Edition (TCO 6) Different From Task List 5?

The field of Applied Behavior Analysis (ABA) is constantly evolving, and with it, the standards and competencies expected of behavior analysts. In an effort to ensure that professionals in the field remain up-to-date and provide the highest quality services, the Behavior Analyst Certification Board (BACB) periodically reviews and revises the task lists that form the basis of their certification exams. In this article, we will discuss the changes made with the new Test Content Outline (TCO) 6 affecting examinations starting January 1, 2025.

One of the notable changes to the BCBA TCO is the retention of the nine content domains from the previous edition. However, there have been four minor revisions to domain titles to enhance clarity and organization. Additionally, the content within each domain has been reorganized to improve the flow and eliminate redundancies across domains, providing a more coherent structure for candidates preparing for the examination.

To enhance the clarity of the task statements, revisions have been made to the retained task statements. These revisions involve the use of purposeful verbs, ensuring that the expectations and responsibilities of BCBAs are communicated effectively. Clear task statements enable aspiring professionals to understand the specific skills they need to develop and demonstrate in their practice.

An important change in the BCBA TCO is the reconfiguration of the Ethics domain. Previously, the domain covered references to the entire Ethics Code for Behavior Analysts. However, in the revised task list, the Ethics domain has been retitled as "Ethical and Professional Issues" and now includes 12 specific tasks. This change provides candidates with a more focused and targeted approach to ethical decision-making and professional conduct.

In recognition of the importance of diversity, equity, and inclusion within the field of ABA, content related to these topics has been integrated into six tasks across three domains. This reflects the growing understanding that cultural competence and sensitivity are essential for behavior analysts when working with diverse populations. By incorporating these elements into the task list, the BCBA certification process now emphasizes the importance of promoting inclusivity and providing culturally appropriate services.

Overall, the revisions to the BCBA TCO have resulted in a net increase of two tasks, bringing the total to 104. These additions and modifications reflect the evolving needs and demands of the field. As part of this change, nine tasks were removed, and ten tasks were combined into five, streamlining the content and eliminating redundancy.

Furthermore, thirteen new tasks have been introduced in the BCBA TCO, although some elements of these tasks were previously included in other statements. These additions address important aspects of behavior analysis practice:

B.20 Identify the role of multiple control in verbal behavior. 
B.22 Identify ways behavioral momentum can be used to understand response persistence. 
B.23 Identify ways the matching law can be used to interpret response allocation. 
B.24 Identify and distinguish between imitation and observational learning. 
C.12 Select a measurement procedure to obtain representative procedural integrity data that accounts for relevant dimensions (e.g., accuracy, dosage) and environmental constraints. • 
D.3 Identify threats to internal validity (e.g., history, maturation). 
D.6 Critique and interpret data from single-case experimental designs. 
E.2 Identify the risks to oneself, others, and the profession as a result of engaging in unethical behavior. 
E.8 Identify and apply interpersonal and other skills (e.g., accepting feedback, listening actively, seeking input, collaborating) to establish and maintain professional relationships.
F.2 Identify and integrate relevant cultural variables in the assessment process. 
G.18 Evaluate emotional and elicited effects of behavior-change procedures. 
H.5 Plan for and attempt to mitigate possible relapse of the target behavior. 
I.3 Identify and implement methods that promote equity in supervision practices.

By including these new tasks, the BCBA certification process ensures that professionals possess the knowledge and skills required to address the complex demands of their role effectively.

The BCBA Test Content Outline has undergone several important changes based on the results of the recent Job Task Analysis. These modifications, which include revisions to task statements, reorganization of content, and the integration of diversity, equity, and inclusion, reflect the evolving nature of the field and the increasing expectations placed on behavior analysts. Aspiring BCaBAs should familiarize themselves with these changes and ensure that their knowledge and skills align with the updated task list to successfully meet the demands of the certification examination and provide high-quality services in the field of ABA.
