Thanks AEH, so in this case the child scored 4th percentile for handwritten essay and 99th percentile for a second typed essay. Clearly many things went well with the essay. The suggestion that something about the essay implied ASD is fuzzy, clearly far fuzzier than what can be captured by the standardized scoring system of an academic test. Is perhaps related to drawing the reader in (or not), ie forging social connections... Perhaps that is captured by "personal narrative qualities of the prompt".

This is an observation I have not ever heard before with relation to this sort of testing so I am quite intrigued.
