Start Here#
Use this hub for the official facts, then move to the page that matches the question blocking your next study step.
- Start with a full-length rbt mock exam when you need pacing practice across all domains. A mock set is useful after you have reviewed the facts below and want mixed application, not a guaranteed prediction.
- Use the planned how long is the rbt exam page before timing practice. That companion will focus on the appointment clock, tutorial time, and realistic pacing decisions.
- Use the planned what to bring to rbt exam checklist before test day. Identification and check-in rules belong there instead of being repeated in full on this hub.
- Review the results companion when you want the after-test sequence. That planned page covers what the official result means without turning practice percentages into BACB cutoffs.
- For more practice now, try the public free RBT practice test without an account. Sign in through the RBT practice app when you want saved attempts and corrections.

Official Scored-Exam Weights#
The RBT Test Content Outline table below describes scored exam coverage, not a practice-test score target.
| Domain | Official scored questions | Official rounded percent |
|---|---|---|
| A. Data Collection and Graphing | 13 | 17% |
| B. Behavior Assessment | 8 | 11% |
| C. Behavior Acquisition | 19 | 25% |

For a narrow count question, the how many questions are on the rbt exam page breaks down scored and unscored items in more detail. For difficulty planning, is the rbt exam hard compares format, pacing, and pass-rate context without promising an outcome.
How To Study From This Hub#
Use official counts for planning, then use missed practice items to decide what to review. A simple study loop is: read the official format, take a small mixed set, sort misses by TCO task, study the weakest task family, then return to timed practice.
The BACB does not endorse a private passing cutoff, so a practice score should stay a study signal. When you need outcome context later, the planned rbt exam pass rate page will summarize official historical pass-rate data separately from your own practice results.
The planned rbt exam accommodations page will cover request timing and documentation rules from the handbook. The planned rbt exam test anxiety page will focus on pacing and test-day routine, not health claims or score guarantees.
Practice Allocation On This Page#
These four original items practice RBT-relevant tasks while staying inside this page's exam-prep context. The allocation below is this page's practice mix, not the BACB scored-exam weighting.
| Domain | Items on this page | Task tags used |
|---|---|---|
| A. Data Collection and Graphing | 2 | A.6, A.7 |
| E. Documentation and Reporting | 1 | E.4 |
| F. Ethics | 1 | F.6 |
Practice Questions#
Answer these original items before reading the rationales. They are study questions written from the TCO and BACB source rules, not recalled exam content.
1. During review, Nina answers 16 of 20 original practice items correctly before opening the rationales. Which percentage summarizes that set?
A Sixteen divided by 20 is greater than 70%, so this understates the review result.
B Seventy-five percent would be 15 of 20, not 16 of 20.
C Correct. A.6 includes calculating and summarizing data; 16 divided by 20 equals 80%.
D Eighty-five percent would require 17 of 20, so this overstates the result.
2. A practice log shows Data Collection scores of 42, 51, 59, and 64 across four review days. Which description is most objective?
A Correct. A.7 requires identifying trends in graphed data, and the values rise across the review days.
B Inconsistent would fit points that move up and down without a clear direction.
C Unchanged would fit values that stay at about the same level.
D Decreasing would fit values that become lower across review days.
3. During a session, Omar writes a note after a teaching program. Which entry is most objective for a session record?
A Difficult is a judgment and does not describe the observable response.
B Wanted attention is a hypothesis about function rather than a session fact.
C Upset all session is broad and does not state a measurable response.
D Correct. E.4 requires objective communication about what occurred, and this entry states an observable action with a count.
4. An RBT posts, "Our practice scores guarantee passing the BACB exam," on a clinic social account. Which edit best fits Code 2.0?
A RBT Ethics Code 2.0 standards 1.01 and 1.05 do not allow false, misleading, or exaggerated public claims.
B Correct. RBT Ethics Code 2.0 standards 1.01 and 1.05 support truthful, non-misleading public statements.
C RBT Ethics Code 2.0 standards 1.01 and 1.05 do not support presenting a private practice score as a replacement for official BACB requirements.
D RBT Ethics Code 2.0 standard 1.05 and the BACB trademark notice do not support calling a private score BACB approved.
