For Professors

The TL5 (v9) version of the CBA Learning Modules Series is based on the BACB's 5th Edition Task List and has over 4,000 learning module questions, plus Unit Pre-/Post-Tests and a Mock Exam!


  Our Methodology:

We know from research that active responding makes for efficient learning. This is why the CBA Learning Module Series is primarily question-based, and most of the questions include: 

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

Each 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 each until 100% correct is achieved. 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.

There is a limit to the number of times that modules can be accessed. Although this limit is generous, please do not quit the module and forfeit the run. Each subscription provides 20 attempts to reach criterion (100% correct) and even more additional attempts for post-criterion practice. The number of additional attempts is dependent on the subscription duration purchased.

On average, the CBA Learning Module Series takes 80 hours to complete all of the learning modules to 100% correct, but there is a great deal of variability in these data. We recommend that learners begin preparing with the CBA Learning Module Series 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. Longer subscriptions are available for additional practice and integration with coursework.



The CBA Learning Module Series TL5 (v9) includes both Unit-Tests and Mock Exam assessments. The key differences are that Unit-Tests are designed to provide a comprehensive evaluation of mastery over the Unit, including definitions, concepts, and applications; whereas the Mock Exam attempts to replicate the actual BCBA exam (which is mostly application questions) and to evaluate learner preparedness. The two types of assessments were developed independently and are designed to measure generalization of the skills taught in the learning modules.


Pass Guarantee

We offer a money-back guarantee on the CBA Learning Module Series. That's right; if you complete all 200 learning modules sets to criterion (100% correct) within the 6 months preceding your exam and don't pass, you may request a full refund or free extension. Completion of the Unit-tests and Mock Exam assessments are not required for eligibility. Free extensions are available if at least 70% of the learning modules were completed to criterion within the same time frame. See the Pass Guarantee page for details on our Money-Back & Free Extension Policies.
