The BCBA exam content outline, explained
The BCBA examination is built on the Test Content Outline (6th ed.), which organizes examinable content into nine domains lettered A through I: behaviorism and philosophical foundations, concepts and principles, measurement and data display, experimental design, ethical and professional issues, behavior assessment, behavior-change procedures, selecting and implementing interventions, and personnel supervision and management. The outline replaced what earlier editions called the BCBA task list.

Is the BCBA task list the same as the Test Content Outline?
Functionally, yes — the Test Content Outline is the current name for what older editions called the task list. It defines the content the BCBA examination can assess. The 6th edition applies to examinations from 2025 onward. Because editions change, always confirm which outline applies to your exam date in the current BCBA Handbook before you build a study plan around it.
The nine domains at a glance
| Domain | What it covers |
|---|---|
| A. Behaviorism and philosophical foundations | The assumptions and philosophy behind behavior analysis as a science. |
| B. Concepts and principles | Reinforcement, punishment, stimulus control, motivating operations, verbal behavior. |
| C. Measurement, data display and interpretation | Choosing measures, IOA, graphing, visual analysis. |
| D. Experimental design | Single-case designs and demonstrating functional relations. |
| E. Ethical and professional issues | Applying the Ethics Code for Behavior Analysts. |
| F. Behavior assessment | Preference, skill and functional assessment; writing measurable goals. |
| G. Behavior-change procedures | Acquisition and reduction procedures, prompting, generalization. |
| H. Selecting and implementing interventions | Choosing procedures, treatment integrity, data-based decisions. |
| I. Personnel supervision and management | Training, supervising and evaluating the people who deliver services. |

How do I know what to study first?
Reading the outline front to back treats every domain as equal, and they are not — not in exam weighting, and not in your own preparation. A faster approach is to rate your confidence on every topic, then spend your next study block on the weakest domain rather than the next page.
- Rate every topic honestly — 'familiar' is not 'can apply'.
- Study the weakest domain first, with active practice (scenario labeling, graphing real data), not re-reading.
- Re-rate weekly; a domain you mastered in January can decay by April.
- If you supervise trainees, rate their demonstrated competence the same way to plan supervision targets.
Our free BCBA task list checklist walks you through all nine domains this way — rate each topic, get a ranked study-priority list, and copy the summary into your study planner. It works without an account; ratings save in your browser until you choose to keep them permanently.
What changed between the 5th edition task list and the 6th edition outline?
The 6th edition reorganized content into the nine-domain structure and updated wording and emphasis across domains — including a dedicated personnel supervision and management domain. Study materials built for the 5th edition task list do not map one-to-one onto the current outline, so check the edition date on any course or textbook before relying on it for a 2025-or-later exam.
For supervisors: using the outline as a fieldwork framework
The same nine domains work as a supervision framework. Rating a trainee's demonstrated competence domain by domain turns 'how is the fieldwork going?' into specific targets — and gives both parties a record of growth across the supervised experience.
Frequently asked questions
- What is on the BCBA exam?
- Content defined by the current Test Content Outline: nine domains covering philosophical foundations, concepts and principles, measurement, experimental design, ethics, behavior assessment, behavior-change procedures, intervention selection and implementation, and personnel supervision.
- Is the BCBA task list the same as the Test Content Outline?
- The Test Content Outline is the current name for what earlier editions called the task list. The 6th edition applies to examinations from 2025 onward.
- How should I study for the BCBA exam content outline?
- Self-assess every topic first, study the weakest domain with active practice, and re-rate regularly. Spaced, retrieval-based study beats re-reading the outline.
- Where do I get the official Test Content Outline?
- From bacb.com — the current edition is published in the BCBA section and referenced in the BCBA Handbook. Third-party summaries, including this guide, are orientation aids only.
How this works in Operation Optimize
