I haven’t heard the term Clerical Motor Speed Weakness before, but I’m assuming it’s slow processing speed. My son also has this as many with ADHD do. In school, extended time on tests and assignments will be key. When he’s old enough to be expected to take notes in class, they should be provided to him. Anything that takes some speed with processing and responding will require some leeway for his success.
In general, allowing him more time to process and answer. When my son was young I’d count to 5 in my head before I expected a response after talking to him. Most of the time he was processing and going to respond but I didn’t give him enough time.
