Spelling methods are the only methods I’ve seen that effectively address the motor issues, including impulsivity. I typically do not see AAC devices introduced in a way that prevents impulsive selections. This hinders the nonspeaker’s ability to select what they truly want to select. This is why families are seeing success with spelling when they haven’t seen that same progress with years of other methods taught through speech therapy and special education.

You said, "Another method is for the facilitator to hold a letter board and issue any number of prompts while the client points with a finger or pencil."

You did not differentiate between the types of prompts, nor did you mention that as the speller progresses in skill and accuracy, the prompts are faded. This is common in any type of coaching, and even in other autism therapies. A nonspeaker's communication is not considered to be self-authored until he/she can point to letters accurately with no one giving prompts that guide the speller to specific letters. It would have been beneficial if you had talked to practitioners about the difference between the aquisition phase and the autonomous phase.

During aquisition, the practitioner may give directional prompts to guide the speller to specific letters to answer questions with one known answer. This is how the practitioner helps the speller develop the neural pathways to accurately and consistently point to the desired letters. It's no different than a golf coach helping a beginning golfer with club choice, grip, and swing.

After a speller becomes accurate and consistent at pointing to desired letters, the practitioner can ask questions without knowing how the speller will respond. At this stage, the only prompts provided are eye prompts like "look at the board, move your eyes" or continuation prompts like "find your next letter, keep going". And beyond that, a practitioner might offer encouragement, like "you've got this, trust yourself".
