The PTB Crosswalk is intended to help students transition from the BCBA or BCaBA 5th Edition Task List exam to the 6th Edition Test Content Outline exam, effective January 1, 2025. Each crosswalk reflects a side-by-side comparison and contrast of the new 6th Edition TCO Domains (formerly known as Task List Sections under the 5th Edition), with detailed notations reflecting additions, revised terminology, removal of language, whole new Domain items, among other vital distinctions.

Written by PTB founder Dana Meller, MA, BCBA and peer-reviewed by Tyra Sellers, JD, Ph.D., BCBA-D, CEO of Association of Professional Behavior Analysts (APBA).
