[U4Q] Dаwn, а behаviоr analyst, is recоrding a behaviоr technician's implementation of a client's behavior program. The behavior technician has implemented it with an average of 60% accuracy in three observations. Dawn discusses this performance with the behavior technician and sets a new goal for the behavior technician of increasing accuracy of implementation to a goal of 80% at first, and then eventually to a goal of 100%. Given this scenario, which criteria for setting goals with her behavior technician is Dawn following?
