The RBT exam passing score is not published as a fixed percentage, raw score, or scaled cutoff. Per the RBT Handbook, the BACB uses the modified Angoff method to set the passing score, and the result is based on overall performance across the scored exam.
What the BACB publishes#
The facts table separates official scoring information from study-site shortcuts.
| Question | Current BACB answer | Source |
|---|---|---|
| Is there a public passing percentage? | No. The RBT Handbook publishes the scoring method, not a fixed percentage cutoff. | RBT Handbook, Scoring Methodology |
| How is the passing score set? | The BACB uses the modified Angoff method to establish the RBT examination's passing score. | RBT Handbook, Scoring Methodology |
| How many exam questions are scored? | 75 scored questions, with 10 unscored questions included on the exam but not scored | RBT Handbook, Examination |
| Are content areas scored separately? | No. The RBT Handbook says the result is based on overall performance, not performance in each content area. | RBT Handbook, Examination |
| How many answer options are on each item? | 4 possible answers and only 1 correct answer | RBT Handbook, Examination |
| Where is the exam delivered? | in person at authorized Pearson VUE testing sites and US military bases | RBT Handbook, Scheduling |
Facts on this page were checked against the RBT Handbook updated 06/2026, the BACB Examination Information page retrieved 2026-10-01, and the RBT Test Content Outline (3rd ed.) updated 09/2024.
The broader rbt exam hub connects scoring with item count, scheduling, delivery, retakes, and test-day rules. Use that page when a scoring question depends on another exam rule.
How the modified Angoff method works#
The modified Angoff method is criterion referenced. Per the RBT Handbook, BACB-certified subject matter experts determine the passing score for the exam form, and the BACB Board of Directors approves it.
That method means candidates should not reverse-engineer a cutoff from practice tests. A practice set can reveal weak areas, pacing problems, and missed definitions, but a practice percentage is not the BACB's passing standard.
The RBT Handbook also says each scored question is equally weighted. A candidate's result comes from overall performance, so a low practice score in one content area should guide review rather than imply a separate domain failure.
Official pass-rate tables#
The BACB examination information page reports historical RBT examination outcomes. The first-time table is useful context, but it is not a personal probability.
| Year | Value (percent) |
|---|---|
| 2021 | 83 |
| 2022 | 77 |
| 2023 | 74 |
| 2024 | 73 |
| 2025 | 75 |
The retake table shows different outcomes for candidates who test again after an unsuccessful attempt.
| Year | Value (percent) |
|---|---|
| 2021 | 53 |
| 2022 | 44 |
| 2023 | 41 |
| 2024 | 36 |
| 2025 | 38 |
Candidate volume also changed across the published years, which matters when comparing pass-rate movement.
| Year | Value |
|---|---|
| 2021 | 43452 |
| 2022 | 58322 |
| 2023 | 73690 |
| 2024 | 90741 |
| 2025 | 109341 |
For a page focused only on year-by-year outcomes, the rbt exam pass rate guide is the better companion. The passing-score question is narrower: what score is needed, and why the exact cutoff is not public.
Official content weights are not a score cutoff#
The RBT Test Content Outline (3rd ed.) gives the official scored-domain allocation. The table below describes exam coverage, not a passing rule.
| Domain | Official scored count | Official rounded percent |
|---|---|---|
| A. Data Collection and Graphing | 13 scored questions | 17% |
| B. Behavior Assessment | 8 scored questions | 11% |
| C. Behavior Acquisition | 19 scored questions | 25% |
| D. Behavior Reduction | 14 scored questions | 19% |
| E. Documentation and Reporting | 10 scored questions | 13% |
| F. Ethics | 11 scored questions | 15% |
Timing can still affect score performance because the RBT Handbook gives one appointment clock for screens and questions. The how long is the rbt exam page explains the time limit and how to practice pacing without treating a stopwatch as a score predictor.
Myths on other sites#
The myths table shows common scoring claims that conflict with BACB sources. Study materials should match the Handbook, not repeat a popular shortcut.
| Wrong claim | Correct fact | Source |
|---|---|---|
| The RBT exam has a public scaled cutoff. | The RBT Handbook reports a pass/fail result and says the passing score is established by the modified Angoff method. | RBT Handbook, Scoring Methodology |
| A fixed percentage tells every candidate how many questions can be missed. | The BACB does not publish a fixed passing percentage; practice percentages are private study benchmarks. | RBT Handbook, Scoring Methodology |
| The scored item count alone reveals the passing mark. | The exam includes scored and unscored questions, and the passing score is set for exam forms through the BACB process. | RBT Handbook, Examination and Scoring Methodology |
| A practice-site score band predicts the official result. | Practice bands can guide review, but the BACB result is based on the official examination and its scoring method. | RBT Handbook, Scoring Methodology |
Test-day logistics can create avoidable mistakes before content knowledge is tested. The what to bring to rbt exam checklist covers identification and appointment rules so scoring myths do not distract from the required exam-day details.
What score should you aim for in practice?#
A good practice target is high enough that misses leave a clear review trail, not a promise that the BACB will call the result passing. Treat every missed item as belonging to one of four buckets: content definition, scenario wording, calculation, or pacing.
A full-length rbt mock exam is useful because mixed items force switching across domains. After the attempt, read every rationale and sort missed items by TCO task before taking another timed set.
The official score report should be read separately from practice results. The planned rbt exam results guide explains what happens after the test and how to interpret the official notification without turning practice percentages into unsupported cutoffs.
Practice items#
The practice table below describes this page's original questions. The allocation is not the official exam weighting.
| Page item domain | Items on this page | Task tags used | Official scored-exam reference |
|---|---|---|---|
| A. Data Collection and Graphing | Questions 1-2 | A.6, A.7 | 13 scored questions, 17% |
| F. Ethics | Question 3 | F.6 | 11 scored questions, 15% |
These original items test score interpretation, trend reading, and ethical score claims. They are not a passing-score calculator.
1. Mateo completes 14 of 18 original practice questions correctly during a mixed review set. Which percentage best summarizes the result?
A Dividing 14 by 18 gives more than 68%, so the percentage is too low.
B Seventy-two percent is still below 14 divided by 18.
C Correct. A.6 includes calculating and summarizing data; 14 divided by 18 is about 78%.
D Eighty-four percent is higher than the quotient from 14 divided by 18.
2. Priya graphs practice scores for data-collection items across four review days: 40, 48, 55, and 61. Which summary best fits the graph?
A A flat pattern would stay near the same level across review days.
B Correct. A.7 requires identifying trends in graphed data, and the points rise across days.
C The points do not bounce sharply up and down, so variability is not the main pattern.
D A downward pattern would show lower scores over time.
3. A study-group post says a private practice score guarantees the same official exam result. Which revision best fits ethical public communication?
A Correct. F.6 covers public statements, and RBT Ethics Code 2.0 standards 1.01 and 1.05 require honest, non-misleading statements.
B A private practice score does not guarantee an official BACB result.
C Calling a private cutoff BACB approved would misrepresent the source of the claim.
D Missing context can leave readers with a misleading statement about exam outcomes.
FAQ
What score do you need to pass the RBT exam?
The BACB does not publish the exact RBT exam passing score. The RBT Handbook says the BACB uses the modified Angoff method to establish the passing score, so a fixed public percentage is not the official rule.
How many questions can you miss on the RBT exam?
The BACB does not publish a number of questions candidates can miss and still pass. The exam has 75 scored questions and 10 unscored questions, but the passing score is not released as a missed-question count.
Is there an RBT exam pass score?
Yes, there is a passing score for each exam form, but the BACB does not publish it as a public cutoff. The RBT Handbook explains the scoring method instead of giving a universal percentage.
Does a mock exam percentage predict the BACB result?
A mock exam percentage can guide study, but it cannot predict the official result. Use missed questions to choose review tasks, then retest with mixed items and rationales.
Is the RBT exam scored by domain?
No. The RBT Handbook says the result is based on overall performance, not performance in each content area. Domain weights describe the scored exam blueprint, not separate pass marks.
