BCaBA · the assistant behavior analyst certification exam
You draft the plan. A BCBA signs beside you.
The assistant exam covers the same concepts as the BCBA at the depth a supervised practitioner needs, and every BCaBA practises under a supervising BCBA. So the exam asks the questions a supervision log is full of: the data, the baseline, the feedback you take.

Today’s entry · a real item from High-yield 1
A BCaBA's supervising BCBA points out that her data-collection errors are affecting a client's program. The most professional response is to:
Accepting corrective feedback means acknowledging it and adjusting behavior to protect the client. (A) Justifying deflects; (C) Demanding writing before acting delays a client-affecting fix; (D) Seeking a new supervisor avoids the feedback.

How you’ll study · the bridge
The same science as the BCBA. Walked once, properly.
The BCaBA task list shares its concepts with the BCBA’s and stops at the depth a supervised practitioner needs. Every item here carries its content area, so your record shows which part of the bridge is still being built.

What’s inside
Five things built for supervised practice.
Every plan opens everything. These are the five that matter most for this exam.
01
Nine full-length forms of 175
Two Diagnostics, two On-level, two Gauntlets and three high-yield drills, each the real 175-item, four-hour shape.
02
Synk Forms in three strengths
Every paper as Standard, Medium and Hard, so a retake is never the same paper: 3,070 of them written fresh.
03
Every wrong answer gets its reason
Each distractor gets its own line, so you learn the idea you confused it with. The plan page above, as a real item:
A supervisor rejects a plan to introduce treatment after only two highly variable baseline points. What is the best rationale for waiting?
Correct (D): Waiting for stability lets you attribute later change to treatment instead of baseline variability. (A) Two variable points do not establish stability. (B) Variability obscures effects, not clarifies them. (C) There is no fixed two-point rule.

Axon Live draws the record
“Name the schedule: reinforcement after a varying number of responses, averaging five. Now — what does the cumulative record look like, and why is there almost no pause after each reinforcer?”

Your topics as a living graph, clustered by content area, so you see the hole rather than a list of percentages.

Questions
Before you start
Are the mocks the real length?
Yes. The real BCaBA exam is 175 questions in four hours, 150 of them scored. Our Diagnostic, On-level and Gauntlet forms are 175 items, weighted across the content areas the way the exam is; the high-yield drills deliberately are not.
Are these real exam questions?
No. Every item is original, written to the public content outline and checked blind by a second AI model that never sees the key. Nothing is copied from a published form, and we are not affiliated with any examining board.
How does the free day work?
Create an account and everything opens for one day — forms, lectures, Axon’s free minutes. No card. Keep it from $49 a month.
I have an access code. What do I do?
Create your account, open the course, and enter the code in Billing & Subscription or on the plan screen. A code opens the product without a subscription.
