Finished your 40-hour course and wondering what stands between you and the RBT exam? For most new behavior technicians in Iowa, the answer is the Initial Competency Assessment. It is the hands-on step where a qualified assessor watches you carry out the core tasks of the job and signs off that you can do them safely and correctly. Many people find free RBT training online, complete the coursework, and then stall because they do not know who can assess them, when the assessment has to happen, or how the 180-day training rule works. This guide walks through each of those questions using the current Behavior Analyst Certification Board (BACB) requirements. It explains the timeline from the first training hour to the application, the 19 tasks assessors check, and the practical steps that make the assessment go smoothly. If you are training in Muscatine or anywhere else in Iowa, you will also see how an employer such as A New Start ABA fits into the process and why working with an ABA provider usually makes the assessment simpler.
What Is the RBT Initial Competency Assessment?
The Initial Competency Assessment, often shortened to ICA, is a required step for anyone applying for Registered Behavior Technician certification. It confirms that you can perform the tasks described in the RBT Task List in a real or realistic setting, not only answer questions about them.
The 40-hour training teaches the concepts. The assessment checks the skills. The exam then tests your knowledge across the full content outline. All three are part of becoming an RBT, along with a background check and meeting the age and education requirements.
Quick answer: is the competency assessment the same as the RBT exam?
No. The competency assessment is a skills check completed with a qualified assessor before you apply. The RBT exam is a separate, proctored multiple-choice test you schedule after the BACB approves your application.
The 180-Day Rule for the 40-Hour Training
The BACB requires the 40-hour training to be completed in no fewer than 5 days and no more than 180 days. Both the start day and the end day count toward that window.
For example, if you start your training on January 1, 2026, you must finish no earlier than January 5, 2026 and no later than June 29, 2026. If you go past day 180, the hours do not meet the requirement and you would need to complete the training again.
- Minimum length: 5 days, so the course cannot be crammed into a weekend.
- Maximum length: 180 days, counting the first and last day.
- Who provides it: an employer, a university, or an online program. The BACB does not offer the training itself.
- Trainer restrictions: the trainer cannot be related to you, subordinate to you, or employed by you.
Quick answer: do I have to complete RBT training in 180 days?
Yes. The 40-hour training must be finished within 180 days of the day you start, and it must take at least 5 days. Keep your certificate, because it shows the start and completion dates the BACB will review.
When the Competency Assessment Happens
Timing matters as much as the content. The assessment has to follow the training and come close to your application.
- After the training: the assessment is completed after you finish the 40-hour training.
- Within 90 days of applying: the assessment must be completed no more than 90 days before you submit your certification application.
- One or more sessions: it does not have to happen in a single meeting. Many assessors spread it across a few sessions.
- Flexible format: it can take place in person, through live online observation, or by reviewing purpose-made video.
A practical sequence for most Iowa trainees looks like this: finish the 40-hour course, schedule the assessment within a few weeks, complete the background check, then submit the application while the assessment date is still inside the 90-day window.
Who Can Assess You
Not every BCBA can sign your form. The BACB sets clear rules about who can serve as the responsible assessor.
Responsible assessor
- Must be a BCBA or BCaBA who has completed the 8-hour supervision training.
- Must work at, or contract with, the same organization as you and the client involved in the assessment.
- Cannot be related to you, subordinate to you, or employed by you.
Assistant assessors
- Must hold RBT certification or higher.
- Can help with parts of the assessment, while the responsible assessor stays accountable for the result.
The person who delivered your 40-hour training can also be your assessor if they meet these rules. This is one reason many trainees choose to complete their training through the same organization that will employ them.
Quick answer: can I get the competency assessment without a job?
It is harder. The responsible assessor must work at or contract with the same organization as you and the client, so most people complete the assessment through an ABA employer. Applying for an RBT job in Iowa is often the most direct route.
What Assessors Check: The 19 Tasks
The assessment covers 19 tasks grouped into four areas. Your assessor marks each task as completed once you demonstrate it correctly.
Measurement (tasks 1 to 3)
These tasks look at how you collect and record data, such as frequency, duration, and other measures used during sessions. Accurate data is the foundation of every treatment decision a BCBA makes.
Preference assessment and ABC data (tasks 4 to 5)
You will show that you can run a preference assessment to find what motivates a client and record antecedent, behavior, and consequence information when behavior occurs.
Skill acquisition and behavior reduction (tasks 6 to 14)
This is the largest group. It covers teaching procedures, prompting, reinforcement, and following behavior reduction plans written by the supervising BCBA. At least 3 of tasks 6 to 14 must be demonstrated with a client, not only through role-play.
Professionalism (tasks 15 to 19)
These tasks cover communication with supervisors, responding to feedback, maintaining client dignity, and following professional and ethical boundaries.
How Each Task Is Assessed
Assessors can use three methods, depending on the task:
- With a client: you perform the task during a real session while the assessor observes.
- Role-play: the assessor or a colleague acts as the client.
- Interview: you explain how and why you would carry out the task.
Corrective feedback is allowed between attempts, so you can practice and try again. Feedback is not allowed during the final attempt that counts toward the sign-off. The responsible assessor keeps the completed records for 7 years, and only the official BACB form is accepted.
How to Prepare for the Assessment
Preparation turns the assessment from a stressful test into a routine check. These steps help most trainees:
- Review your training notes by task: match each module to the 19 tasks so you know where each skill was taught. Our RBT exam study guide lays out the content areas in order.
- Practice data collection out loud: run short practice trials with a peer and compare your data.
- Ask for a mock run: many supervisors will walk through role-play tasks before the formal assessment.
- Know the vocabulary: be ready to explain prompting, reinforcement, and extinction in plain language.
- Bring questions about ethics: the professionalism tasks often come up in interview format.
Where to Find Free RBT Training Online and Assessment Support in Iowa
Several online providers offer the 40-hour course at low or no cost, and some Iowa employers cover training for new hires. We list options in our guide to free RBT training near you. When you compare programs, check three things:
- The course meets the current 40-hour requirements and shows start and completion dates.
- The trainer meets BACB rules and is not related to or employed by you.
- You have a plan for the competency assessment, which online courses usually do not provide on their own.
That last point is where an employer matters. At A New Start ABA in Muscatine, new technicians can complete training and the competency assessment with a qualified BCBA on the same team that supports the families they work with. If you want a broader look at how long the whole process takes, read how long it takes to get RBT certification.
Common Mistakes That Delay Certification
- Letting the 90-day window lapse: if you wait too long to apply after the assessment, you may need to repeat it.
- Finishing the training too fast or too slow: fewer than 5 days or more than 180 days will not count.
- Using an ineligible assessor: a BCBA outside your organization, or one without the 8-hour supervision training, cannot sign the form.
- Using an outdated form: download the current form from the BACB RBT page before your first session.
Frequently Asked Questions
How long does the RBT competency assessment take?
There is no fixed length. Some trainees finish in one long session, while others complete it over several shorter sessions. The time depends on how quickly you demonstrate each of the 19 tasks and on client availability for the tasks that must be done with a client.
Can the competency assessment be done online?
Yes. The BACB allows live online observation and purpose-made video in addition to in-person assessment. At least 3 of tasks 6 to 14 still need to be demonstrated with a client.
What happens if I fail a task?
You can receive corrective feedback and try again. The task is marked complete only when you perform it correctly on an attempt without feedback.
Is free RBT training online accepted by the BACB?
It can be, as long as the course meets the 40-hour requirements, the trainer is eligible, and the training is completed within the 5 to 180 day window. Cost does not affect acceptance.
Does my 40-hour trainer have to be my assessor?
No, but they can be if they meet the assessor requirements. Many trainees use the same person because it keeps the process inside one organization.
How long is the competency assessment valid?
For the initial application, it must be completed no more than 90 days before you apply. After certification, RBTs complete a separate renewal competency assessment as part of recertification.
Do I need the assessment before I can work as a behavior technician in Iowa?
Many Iowa employers hire behavior technicians while they complete training and the assessment, then support them through certification. Insurance-funded ABA in Iowa generally expects services to be delivered by qualified, supervised staff, so certification is usually part of the job plan.
