**Short answer:** The BCBA exam has 185 multiple-choice questions (175 scored) based on the BCBA Test Content Outline, 6th edition, across nine domains. Most people pass with a structured plan: study each domain against the outline, practice applying concepts to scenarios, take timed full-length mock exams, and review every wrong answer until you can explain why.

**Key takeaways**
- The exam has **185 questions**, **175 scored**, across **nine domains**.
- Study **against the 6th edition outline**, domain by domain.
- Practice **applying** concepts to scenarios, not just memorizing terms.
- Take **timed mock exams** and **review every miss**.

## What's on the BCBA exam?

The 6th edition Test Content Outline covers nine domains:[1]

| Domain | Topic |
| --- | --- |
| A | Behaviorism and philosophical foundations |
| B | Concepts and principles |
| C | Measurement, data display and interpretation |
| D | Experimental design |
| E | Ethical and professional issues |
| F | Behavior assessment |
| G | Behavior-change procedures |
| H | Selecting and implementing interventions |
| I | Personnel supervision and management |

Check the outline for the number of questions per domain, and weight your study time to match.[1]

## What's a good 12-week study plan?

1. **Weeks 1 to 2:** read the outline, take a diagnostic mock exam, list your weakest domains.
2. **Weeks 3 to 8:** one or two domains a week. Make your own examples for every term.
3. **Weeks 9 to 10:** mixed practice questions and one timed full-length mock per week.
4. **Weeks 11 to 12:** review missed questions, ethics scenarios and measurement calculations. Rest before test day.

**Explain it out loud.** If you can explain a concept to a study partner with a real example from your fieldwork, you'll recognize it in a
  scenario question.

## What study habits help most?

**Try:**
- Short daily sessions over long weekend cramming
- Writing your own client examples for each concept
- Timed mock exams to build stamina
- A study group that quizzes each other on scenarios

**Skip:**
- Memorizing definitions without applying them
- Only doing questions you already get right
- Skipping ethics because it seems obvious

## What should I do on test day?

- Arrive early at the Pearson VUE center with the right ID.
- Pace yourself; flag hard questions and come back.
- Read every option. Many questions hinge on one word.
- Eat and hydrate beforehand. It's a long exam.

**Check the handbook.** Registration, retake rules and accommodations are in the BCBA Handbook. Requirements can change, so read the current
  version.
