Continuing the series on the series on Effective ABA Instructional Interventions, the next prompt fading strategy to address is Most-to-Least prompt fading. Like least-to-most fading that I talked about in the last post in the series, this fading procedure involves using the hierarchy of prompt types to fade them out. However, as it is named, you start with the most intrusive prompt and gradually reduce the intrusiveness of the prompts until the student is independent.
