Which type of prompt hierarchy begins with the most intrusive prompt required to gain correct responding and fades as success is observed?

• A. Most-to-Least Prompting (MtL)
• B. Least-to-Most Prompting (LtM)
• C. Prompt Hierarchy
• D. Antecedents

Answer: (A)

This describes Most-to-Least Prompting. Start with the strongest prompt that guarantees a correct response, then progressively fade to less intrusive prompts as the learner shows more consistent correct responding. This approach helps establish the correct stimulus–response connection with minimal errors, because the learner receives enough support at first and gradually becomes more independent as accuracy improves. It differs from Least-to-Most Prompting, which starts with the least prompting and adds prompts only if the learner doesn't respond correctly. A Prompt Hierarchy is the set of prompting levels, but it doesn’t specify the direction of fading. Antecedents refer to cues before a behavior and aren’t a prompting strategy.
