BCaBA Exam Prep

What a BCaBA is

The Board Certified Assistant Behavior Analyst (BCaBA) is the BACB's undergraduate-level certification in behavior analysis. It sits between the RBT, a paraprofessional credential, and the BCBA, which requires a graduate degree.

A BCaBA can take on work an RBT cannot, such as supervising RBTs, delivering the RBT 40-hour training and completing RBT competency assessments. A BCaBA must always practice under the supervision of a qualified BCBA: a BCaBA with no supervisor on record with the BACB is considered inactive and may not practice.

Eligibility

Every route needs a bachelor's degree and supervised fieldwork. There are two pathways:

• Pathway 1 — a bachelor's degree or higher from an ABAI-accredited behavior analysis program, earned in 2015 or later while the program was accredited, plus supervised fieldwork.
• Pathway 2 — a bachelor's degree or higher in any field from a qualifying institution, plus undergraduate-level (or higher) behavior-analytic coursework, plus supervised fieldwork.

Supervised fieldwork

• Between 20 and 130 fieldwork hours per calendar month.
• All fieldwork completed within five continuous years.
• At least 40% of hours in unrestricted activities — the work a BCaBA actually does, such as assessment, training staff and caregivers, and data analysis (for example, 520 of 1,300 hours).
• Supervisors must be active BCBAs with no current disciplinary sanctions who meet the BACB's supervisor requirements.

The BCaBA exam

Since 2025 the exam follows the BCaBA Test Content Outline (6th ed.): 90 tasks in nine domains. The scored questions are distributed like this:

The four largest domains — Behavior-Change Procedures, Measurement, Intervention Development and Monitoring, and Concepts and Principles or Ethics — make up more than half of the scored questions, so they deserve most of your practice time.

Keeping the certification

• 20 continuing education units (CEUs) in every 2-year recertification cycle, including 4 in ethics and, if you supervise, 3 in supervision.
• Ongoing supervision by a qualified BCBA: at least 5% of your behavior-analytic service hours, at least once a month.
• Following the BACB's ethics and self-reporting requirements.

How to study for it

• Start from the outline above. Weight your time by the question counts, not by which topics feel comfortable.
• Take a full-length timed mock early to find your weakest domains, then drill those before taking the next one.
• Practice at exam length. Four hours and 175 questions is a stamina test as much as a knowledge test.
• Review every question you got wrong and write down why the right answer is right.

ABA Sprout's BCaBA prep, part of Career Pro, includes four full-length mock exams of 140 questions each with explanations, plus domain-level results so you can see where your points are going.
