Caregivers report that aggression mostly follows the TV being turned off, a variable the standard conditions do not test. The analysis can be adapted by:

Adding an individualized condition

Running only the alone condition twice

In a multielement design, the effect of one treatment may carry over into the other condition. This is called:

Multiple-treatment interference

Stimulus generalization effects

When may a behavior analyst recommend a punishment-based procedure?

After less intrusive means fail

Before any reinforcement is tried

It has 185 multiple-choice questions in 4 hours, 175 scored and 10 unscored, each with 4 options and 1 correct answer, taken in English on a computer at Pearson VUE testing centers. It follows the BCBA Test Content Outline (6th ed.): 104 tasks in 9 domains, from concepts and principles and behavior-change procedures (14% each) to behaviorism and philosophical foundations (5%). The result is pass or fail against a passing score set by the modified Angoff method, not published as a percentage. Candidates may test up to 8 times in the 2-year authorization period, 30 days apart.

Updated November 2026 by the Tigertest team. Practice questions follow The BACB BCBA Test Content Outline (6th ed.) and the BCBA Handbook (updated November 2026), checked November 2026. Exam rules change, so confirm current details with BACB: BCBA certification.

How It Works

Train by Domain

Five training sets follow the outline in order: philosophy and principles; measurement and experimental design; ethics and behavior assessment; behavior-change procedures and interventions; and supervision and management. Questions you miss come back until you have mastered them.

Weighted Practice Tests

Four practice tests of 50 questions, each weighted like the 175 scored questions on the real exam. Aim for 70% or better. No question appears in more than one test, and every one comes with an explanation.

Built on the BCBA Test Content Outline (6th ed.)

The BACB publishes how many of the 175 scored questions come from each of the nine domains, and every practice test here keeps that balance, scaled to 50 questions. Ethics questions follow the Ethics Code for Behavior Analysts. ABA program faculty can set Tigertest as BCBA review at tigertest.io/teach and see which topics the class misses most.

How to Pass the BCBA Exam

1. Master the principles

Concepts and principles and behavior-change procedures are the two largest domains. Be able to tell reinforcement from punishment in any scenario, name schedules from their patterns, separate motivating operations from discriminative stimuli, and classify the verbal operants.

2. Read graphs and designs fluently

Practice judging level, trend and variability, calculating rate and IOA, and picking the single-case design that fits a question. Know what each threat to internal validity looks like.

3. Know the Ethics Code by situation

Ethics questions describe a case and ask what to do. Learn the Code's standards on competence, confidentiality, multiple relationships, testimonials, social media, consent, discontinuing services and supervision well enough to apply them.

4. Fix your misses, then retest

Tigertest tracks your accuracy by domain. Aim for 70% or better on every practice test before your exam date. After each test, drill the questions you missed and retrain the weakest domain.

BCBA Exam Frequently Asked Questions

What is the BCBA exam?

It is the certification exam for the Board Certified Behavior Analyst credential from the Behavior Analyst Certification Board (BACB). Candidates take it after meeting the degree, behavior-analytic coursework and supervised fieldwork requirements and having their application approved. Passing it earns BCBA certification, the graduate-level credential in behavior analysis.

How many questions are on the BCBA exam?

The BACB's BCBA Handbook says the exam is 4 hours and has 185 multiple-choice questions: 175 scored and 10 unscored. Each question has 4 possible answers with only 1 correct, and all scored questions are weighted equally. It is offered only in English, on a computer at Pearson VUE testing centers.

What score do you need to pass the BCBA exam?

The BCBA exam is pass/fail. The BACB sets the passing score with the modified Angoff method, a criterion-referenced process run by a panel of BCBA subject matter experts, and does not publish it as a percentage. The 70 percent line on these practice tests is a readiness target, not the official standard. Candidates may take the exam up to 8 times within the 2-year authorization period, waiting 30 days between attempts.

What is on the BCBA exam?

The BCBA Test Content Outline (6th ed.) has 104 tasks in 9 domains: Behaviorism and Philosophical Foundations (8 questions), Concepts and Principles (24), Measurement, Data Display, and Interpretation (21), Experimental Design (13), Ethical and Professional Issues (22), Behavior Assessment (23), Behavior-Change Procedures (25), Selecting and Implementing Interventions (20), and Personnel Supervision and Management (19). Each practice test here keeps that balance, scaled to 50 questions.

Are these the real BCBA exam questions?

No. Every question is original, written by Tigertest from the BACB's published test content outline and Ethics Code, so it covers the same knowledge without copying the exam. Graphs are described in words. Tigertest is not affiliated with the Behavior Analyst Certification Board.

I teach an ABA graduate program or verified course sequence. Can my students use Tigertest?

Yes, for free. Make a class at tigertest.io/teach, post one link, and students join with just their name. You see who practiced, their test scores and the topics your class misses most.

BCBA sample questions and answers

6 of the 200 practice questions, one from each topic, with the answer explained.

1. Caregivers report that aggression mostly follows the TV being turned off, a variable the standard conditions do not test. The analysis can be adapted by:
- A.Skipping the control condition
- B.Adding an individualized condition
- C.Removing the play condition
- D.Running only the alone condition twice
Answer: B. Functional analyses can add test conditions for idiosyncratic variables identified in indirect and descriptive assessment, while keeping a control condition for comparison.
2. An instructor teaches a learner to pick a picture when given a spoken word, and to pick a printed word when given the same spoken word. Which untaught relation should be tested for equivalence?
- A.Spoken word to picture
- B.Spoken word to printed word
- C.Picture to the same picture
- D.Picture to printed word
Answer: D. After training spoken to picture and spoken to printed, selecting the printed word given the picture is an emergent relation not taught directly.
3. A child watches a sibling get scolded for climbing the bookshelf and then does not climb it. This is best described as:
- A.Observational learning
- B.Imitation
- C.Echoic behavior
- D.Rule-governed behavior
Answer: A. Observational learning is behavior changing after seeing another person's behavior and its consequences. Imitation requires copying the form of a model's behavior right after it.
4. In a multielement design, the effect of one treatment may carry over into the other condition. This is called:
- A.Observer reactivity
- B.A ceiling effect
- C.Multiple-treatment interference
- D.Stimulus generalization effects
Answer: C. Multiple-treatment interference occurs when behavior in one condition is affected by exposure to another condition, which clouds the comparison.
5. When may a behavior analyst recommend a punishment-based procedure?
- A.When it works fastest
- B.Before any reinforcement is tried
- C.After less intrusive means fail
- D.Whenever a parent asks
Answer: C. Code 2.15: restrictive or punishment-based procedures come only after less intrusive means have not worked, or when risk of harm outweighs the risk of the procedure.
6. After treatment, asking the teacher whether the change made a real difference in class measures:
- A.Social validity of outcomes
- B.Treatment integrity
- C.Interobserver agreement
- D.External validity
Answer: A. Social validity of outcomes asks whether the results are important and satisfying to the client and stakeholders.
