The step that isn’t a test.
The Initial Competency Assessment is where someone qualified watches you do the job and confirms you can do it. No essay, no multiple choice — you demonstrate, they observe. Here’s what’s on it and how to walk in ready.
What you’ll be asked to show
The assessment follows the board’s task list, so nothing on it is a surprise if you’ve done the 40-hour training. It spans roughly these areas:
Measurement
Recording data the way the plan asks for it — counting, timing, and interval recording — and doing it accurately while a session is actually happening.
Assessment support
Running the pieces of an assessment a technician contributes to, including preference assessments that identify what a child will actually work for.
Skill acquisition
Teaching procedures: discrete trials, teaching in the natural environment, prompting and fading, chaining a multi-step routine, and generalizing a skill beyond the room it was taught in.
Behavior reduction
Implementing the behavior plan as written — the antecedent strategies, the replacement behavior, and what you do in the moment — plus describing the function of a behavior in plain terms.
Documentation and reporting
Session notes, objective description, mandatory reporting, and communicating with a supervisor about what changed.
Professional conduct
Scope of practice, responding to feedback, client dignity, and confidentiality. The ethics items are not filler; they are the ones that end careers when they go wrong.
The exact task list and the rules for who may assess you are published by the Behavior Analyst Certification Board at bacb.com, and they get revised. Work from the current handbook, not a blog post — including this one.
How to walk in ready
- 1
Practice out loud, with a person
Reading about prompting is not practicing prompting. Grab a friend, a sibling, anyone, and run the procedures until the words come out without you assembling them first.
- 2
Know your definitions cold, then forget them
You'll be asked to describe what you're doing while you do it. If you have to stop and search for the term, both halves fall apart. Say it enough times that it becomes ordinary speech.
- 3
Ask which tasks are being observed, and in what order
Assessors differ in sequence and in what they'll accept as a demonstration. Two minutes of questions beforehand removes most of the nerves.
- 4
Treat feedback as the point
Being corrected mid-assessment is not failing — it's the assessor doing their job. How you take feedback is itself one of the things being evaluated, and it's the single best predictor of whether you'll be good at this work.
Assessment questions, straight answers
Stuck without an assessor?
That’s the most common reason this process stalls, and it’s the easiest one to fix — it’s part of onboarding here.
