Version 8 of the CBA Learning Modules Series is based on the BACB's 4th Edition Task List and it has over 3,200 learning module questions, plus Pre- and Post-Tests. 

We conducted a survey of individuals who purchased a 6-month CBA LMS v8 license in September and October of 2017.  The pass rate was 91.0% for first time BCBA exam takers, all confirmed by a review of the BACB’s Certificant Registry (

The criterion for inclusion was completion of all learning modules to 100% correct; 107 individuals met this criterion.  Using a combination of Survey Monkey emails, phone calls, and mailed letters, 97 (90.6%) responded. Of these participants, 74 reported taking the BCBA exam one time and passing, 7 reported taking the exam once and failing, 4 reported being retakers and 12 reported not ever taking the exam.  3 of the 74 who reported passing could not be verified on the BACB registry and are not included in the pass rate.  Of the 4 retakers, 3 reported passing (2 of whom could be verified).  

First time BCBA exam taker survey participants took the exam in November 2017 or February 2018. The BACB reports a pass rate of 64.7% and 62.7%, respectively (see:  Note: the BACB pass rate data also includes the CBA Learning Module Series users.  If there were a way to remove the CBA user data from the BACB’s data, the BACB pass rates would be even lower.

Moreover, we offer a money-back guarantee on the CBA Learning Module Series. That's right; if you complete all learning modules to 100% within 6 months from the actual exam date* and fail the exam, you'll get your money back (Pre- and Post-Tests are excluded from the 100% program completion).  Note that some universities may pre-purchase CBA licenses for students and may have instituted a no return policy.  In these cases, Behavior Development Solutions also adopts a no refund policy.

If you complete 70% or more of the modules to criterion (100% correct) within 6 months from the actual exam date* and fail the exam, we'll give you a free extension through the next exam testing month. Weekly and exam session extensions are also available for purchase in our store.

*For customers with licenses over 6 months long, please note that the policy is not from the beginning of the license and that qualifying is measured by completion data recorded within 6 months from the actual exam date. Data from the course completion report is used to determine completion and the begin date can be modified to reflect an exact 6 month date range. 

Please see the Pass Guarantee page for details on our Money-Back & Free Extension Policies. 

We know from research that active responding makes for efficient learning.  This is why the CBA Learning Module Series is mostly question-based.  Most of the 3,200 questions includes: 

  • four multiple choice options
  • corrective feedback for each incorrect option
  • a hint
  • a text book reference for more information on that topic

A learning module set consists of an acquisition module and a duplicate fluency module.  The only difference between the two is that in the acquisition module the timer is set for 60 minutes (designed to be practiced at a leisurely pace) and in the fluency module the timer is set to between 2 to 8 minutes, depending on the number of questions in the module.  The learner practices the acquisition module until 100% correct is achieved, then practices the fluency module to 100% correct.  Upon completion of a fluency module, the learner is responding at a rate of about 4-5 correct questions/minute--fluent responding that fosters maintenance and application. 

We recommend that learners begin preparing with the CBA Learning Module Series at least 6 months before the exam; although, we know that some people can complete the Series in much less time and even if they don't complete it, they are likely to get some benefit with minimal use.

**There are 193 module sets.  A set consists of two types of modules--acquisition and fluency.  Within a set, the content is the same in both types. The number indicated above is the number of guaranteed runs for each module set after criterion is achieved.  A generous number of runs is programmed for attaining criterion as well. Quitting a module prematurely forfeits that run.

Although we will continually improve the CBA Learning Module Series based on new data, for the most part, this version of the program was authored over a period of three years by several experienced behavior analysts--Stephen Eversole, Ed.D., BCBA-D, Dusty Jones, M.S., BCBA, Guy Bruce, Ph.D., BCBA-D, Tom Dozier, M.S., BCBA, Charles Merbitz, Ph.D., BCBA-D, Michael Weinberg, Ph.D., BCBA-D.  Any shortcomings are the responsibility of Steve Eversole.  Click here to view brief biographies of these authors.
