How Many Times Can You Take the BCBA Exam? Attempts, Retakes, and the 2-Year Window
If you are asking how many times you can take the BCBA exam, the current BACB Handbook gives a specific answer: you may take the examination up to eight times within the two-year period following your initial application approval. You must wait at least 30 days between examination appointments.
That answer is not the same as “you get eight unlimited retakes.” The count operates inside an authorization window, and each failed attempt has a follow-up process in the BACB portal. The official handbook also separates the retake policy from eligibility requirements and from any future transition requirements. Use the rule as a planning framework, then confirm the deadline and current instructions in your own portal.
Quick answer
| Policy question | Current handbook answer |
|---|---|
| Maximum examinations | Up to 8 attempts |
| Counting period | Within the 2-year period following initial application approval |
| Minimum interval | Wait 30 days after the previous attempt before retaking |
| Retake application | Available in the BACB portal within 48 hours of a failed attempt, according to the current handbook |
| Current listed retake fees | $140 retake application fee plus $125 examination appointment fee for each retake |
The candidate’s BACB portal includes the specific testing deadline. If your account displays a different date because of your application history or a transition rule, use that account information and contact the BACB when you need clarification. A general article cannot calculate an individual authorization date.
What “eight attempts” means
The current wording is “up to 8 times” within the authorization period. It is more precise to say eight total examination attempts than eight retakes, because your initial examination appointment is part of the total count. If you pass before using all eight attempts, you do not continue taking the certification examination under that authorization.
Attempts are not a yearly allowance that automatically renews. The handbook ties the count to the two-year period that follows initial application approval. The date of approval, the date of each appointment, and the deadline shown in your portal are therefore more important than a generic statement such as “you can test eight times every two years.”
The rule also does not mean that every candidate should plan to use all eight attempts. Each additional attempt costs time and fees, and repeated testing without changing the underlying study approach may provide less useful information. A failed score should lead to a repair plan rather than an automatic decision to schedule the next available date.
The 30-day wait and the 2-year window
After an examination attempt, you must wait 30 days before taking the BCBA examination again. The wait applies between appointments; it is not a suggestion to squeeze two full examinations into the same week. The interval gives you time to obtain the score report, identify content and reasoning problems, study deliberately, and submit the retake application.
The two-year period is the other half of the rule. You may have up to eight attempts available, but all of them must fit inside the authorization period that begins with your initial application approval. If an appointment date, portal authorization, or transition condition is unclear, do not rely on a forum post or an old study page. Check your BACB account and the current BCBA Handbook.
What happens after a failed attempt?
The current handbook says an Examination Retake Application becomes available in your BACB portal within 48 hours of each failed examination attempt. After you submit that application, the handbook says you will receive an examination authorization email within 48 hours with instructions for scheduling a new appointment. The timing of an individual account can vary, so use the portal and current BACB messages as the operational source.
The handbook currently lists a $140 retake application fee and a $125 examination appointment fee for each retake. Fees can change, and the BACB notes that fees are nonrefundable and nontransferable in the handbook. Before paying, review the amount shown in the current account workflow and the appointment terms.
Use the waiting period as a decision cycle:
- Read the result: save the official score report and note the content areas or patterns that need review.
- Diagnose the error: separate missing knowledge, misreading, weak discrimination, data interpretation, and test-taking behavior.
- Repair deliberately: use the current BCBA Test Content Outline to select concepts, scenarios, and practice questions.
- Recheck readiness: use delayed mixed practice, not only a repeat of the same items.
- Schedule responsibly: confirm the 30-day requirement, the portal deadline, and your study capacity before choosing another date.
What happens after eight unsuccessful attempts?
The current BCBA Handbook addresses the situation directly: if you do not pass after eight attempts and still have time remaining in the two-year authorization period, you must wait until that authorization period is over to reapply for BCBA certification. This is why an attempt count cannot be separated from the authorization window.
Reapplication is not the same as simply booking a ninth examination appointment. A new application may require you to review the requirements that apply at that time, submit the appropriate materials, and receive a new approval before testing. Do not assume that an expired authorization preserves every earlier eligibility condition indefinitely.
If you are close to the end of your period, check the date shown in your BACB portal early. Application processing, retake authorization, appointment availability, and transition rules can affect planning. The official handbook and the BACB account are more reliable than an old “how many attempts” answer posted before the current handbook update.
How to handle the 2027 transition question
The BACB has separate pages for 2027 BCBA requirements and transition guidance. That information answers eligibility and application questions; it does not erase the current retake rule described above. A candidate should not assume that the 2027 transition automatically adds attempts, removes the 30-day wait, or extends a personal authorization period.
Instead, keep two checklists:
- Retake checklist: attempt count, last appointment date, 30-day interval, retake application, current fees, and the two-year portal deadline.
- Eligibility/transition checklist: the requirements and transition guidance that apply if you need to reapply or your authorization ends.
For the second checklist, read the current BACB BCBA requirements and transition resources and confirm how they apply to your account. Do not use this article to decide whether your coursework or fieldwork qualifies under a future pathway.
How to use the rule in a study plan
The eight-attempt limit is not a reason to rush into the next appointment. It is a reason to make each attempt informative. Before you schedule a retake, write down what changed since the last attempt: which domains you reviewed, which error types decreased, and whether you can explain decisions in new scenarios rather than recognize answers you have already seen.
Use the BCBA preparation route for a structured study plan, the BCBA practice question route for new scenarios, and the app review loop for delayed retrieval. These are study resources, not official score predictors. Keep the official BACB handbook open when you are making an application or scheduling decision.
FAQ
How many times can you take the BCBA exam?
The current BCBA Handbook allows up to eight total examination attempts within the two-year period following initial application approval.
How long do you have to wait between BCBA exam attempts?
You must wait at least 30 days after an attempt before taking the examination again.
Is it eight retakes or eight total attempts?
The handbook’s wording is up to eight times during the authorization period. Describe it as up to eight total examination attempts rather than promising eight additional retakes after the first attempt.
How soon can you apply for a BCBA retake?
The current handbook says the retake application becomes available in the BACB portal within 48 hours of a failed attempt. You still must follow the authorization and 30-day scheduling rules.
What if I fail eight times?
If you have used eight attempts and still have time left in the two-year period, the current handbook says you must wait until that period ends to reapply for BCBA certification.
Will the 2027 BCBA changes give me more attempts?
Do not assume that. The 2027 requirements and transition guidance address eligibility and application conditions. Check the current guidance and your BACB portal for your situation; this article does not establish an automatic attempt extension.
