ABA Rocks Registered Behavior Technician (RBT) Practice Exam

MSWO is a preference assessment that orders items by relative preference, providing a ranking among items. In this procedure, you present multiple items at once, the learner selects one, and that item is removed from the array for subsequent trials. By repeating with the remaining items, you build a hierarchy from most to least preferred. This ranking helps identify which items are the most potent reinforcers for the learner. It differs from single-item preference checks, which only tell you if an item is preferred at all, and from procedures that use replacement after each choice, which keep all items in play and don’t yield a stable rank.
