Start here: figure out why it didn't pass
The exam is pass/fail. Your result is based on your overall score, not on each section. So you don't need to master everything. You need to stop losing points in the areas where you keep losing them.
The usual reasons people fail more than once
- You know the definitions but can't apply them. Almost every question is a short story about a client and an RBT. If you studied flashcards only, the stories feel unfamiliar.
- You mix up look-alike terms. These are negative reinforcement vs. punishment, DRA vs. DRI vs. DRO, partial vs. whole interval, and generalization vs. maintenance. The wrong answers are written to catch exactly these. See the Mix-ups tab.
- You answer like a supervisor. RBTs follow the plan, collect data and report. They don't design, change or diagnose. When you're unsure, the answer that keeps the RBT inside their role and brings in the supervisor is usually right.
- You run out of time or second-guess yourself. 90 minutes for 85 questions is about a minute each. Changing answers without a clear reason usually costs points.
- You studied old material. Since January 1, 2026 the exam follows the RBT Test Content Outline (3rd ed.), not the old 2nd-edition Task List. If your prep book or app is from before 2025, parts of it are out of date.

A three-week plan
You can retake after 7 days, but booking 2–3 weeks out gives you time to fix the patterns. 30–45 minutes a day beats a long weekend cram.
| Week | Focus | Daily routine |
|---|---|---|
| 1 | Your 2 weakest domains (from the score report and the practice test) | Read that domain's tasks on the 43 tasks tab. Do 15 practice questions in that domain. For every miss, write why the right answer is right in one sentence. |
| 2 | Mix-ups and data math | 10 minutes on Flashcards, 10 on Data math, then a mixed practice set. Re-do your missed questions with the "Missed only" button. |
| 3 | Full timed practice and confidence | Two timed full practice runs this week. Review only your misses. Stop studying new material 2 days before the test. |
What the exam actually is (2026)
Questions by domain (scored items)
Retake rules
- Up to 8 total attempts within 12 months of your first application approval.
- A retake application shows up in your BACB portal within 48 hours of a failed attempt. There's currently no BACB fee for it.
- You must wait 7 days between attempts.
- Pearson VUE charges $45 per appointment. Cancelling or rescheduling within 30 days of the appointment costs a fee.
- If you use all 8 attempts and still have time left in the 12 months, you have to wait for the 12 months to run out before reapplying.
- Arriving more than 30 minutes late means you can't test, and you lose the $45.
Accommodations
If you have a current disability under the ADA (which can include documented anxiety, ADHD or a learning disability), you can request accommodations, such as extra time. You need the BACB Examination Accommodation Request Form plus documentation from a qualified professional (a doctor, psychologist or school official). Approval takes time, so ask before you book.

The mix-ups that cost the most points
Wrong answers are usually the neighbor of the right answer. Learn these pairs and you'll get more questions right across every domain.
1. Did the behavior go up in the future (reinforcement) or down (punishment)?
2. Was something added (positive, +) or taken away (negative, −)?
"Negative" never means "bad." It only means "removed." Escaping homework by screaming is negative reinforcement, because the demand is removed and screaming increases.
Data math drills
Data Collection and Graphing has 13 questions, and some of them are quick math. These are easy points once the formulas stick.
| Measure | Formula |
|---|---|
| Rate | count ÷ time (convert the time to the unit asked, e.g. per hour) |
| Percentage | correct ÷ total trials × 100 |
| Mean duration | total time of all episodes ÷ number of episodes |
| Total duration | add up the time of all episodes |
| Latency | time from the instruction/cue to the start of the response |
| IRT | time from the end of one response to the start of the next |
| % of intervals | intervals scored ÷ total intervals × 100 |
Practice test
These are original scenario questions written in the style of the real exam and spread across the 6 domains in about the same proportions. They are not real exam questions. After each answer you'll see why it's right or wrong. That explanation is where most of the learning happens.

Tap the card to flip it. Say the answer out loud before you flip. Then mark it so the cards you miss come back more often.

How to answer each question
- Read the last sentence first. "Which procedure is this?" and "What should the RBT do next?" call for different thinking.
- Name the domain in your head. Is it data, reinforcement, ethics or reporting? That narrows down what the answer can be.
- Cross out the two worst options. Usually two answers are clearly off, and the real choice is between the other two neighbors.
- Run the RBT check. Does this answer keep the RBT following the plan, documenting objectively and telling the supervisor? Answers where the RBT changes the plan, diagnoses, promises outcomes or handles a clinical problem alone are usually wrong.
- Watch for "BEST," "FIRST," and "MOST." More than one answer might be okay. Pick the one that is safest, most objective, and inside the RBT's role.
- Don't get stuck. If a question is past 90 seconds, pick your best guess, flag it and move on. Every question counts the same, and there's no penalty for guessing, so never leave one blank.
- Only change an answer for a reason. If you misread the question, change it. If it's just a feeling, leave it.
